An air conditioner that operates without electricity is eco-technology. Kitchen appliances for a summer cottage without electricity Determining a suitable model of an installation such as a gas boiler without electricity

A gas boiler without electricity is a traditional model of a floor-standing appliance that does not require additional energy sources to operate. It is advisable to install devices of this type if there are regular power outages. For example, this is relevant in rural areas or dacha areas. Manufacturing companies produce modern models of double-circuit boilers.

They have reduced gas consumption, as well as the ability to adjust heating.

Many popular manufacturers produce different models of energy-independent gas boilers, and they are quite efficient and of high quality. Recently, wall-mounted models of such devices have appeared. Design heating system should be such that the coolant circulates according to the principle of convection.

This means that the heated water rises up and enters the system through the pipe. To ensure that the circulation does not stop, the pipes must be placed at an angle, and they must also be large in diameter. And, of course, it is very important that the gas boiler itself is located at the lowest point of the heating system.

To this heating equipment You can separately connect a pump that is powered from the mains. By connecting it to the heating system, it will pump coolant, thereby improving the operation of the boiler. And if you turn off the pump, the coolant will again begin to circulate by gravity.

Boiler design without electricity

The gas boiler, independent of electricity, has:

• 2 gas burners – pilot and main;
• Combustion chamber - in such devices it is open for better traction;
• Automation;
• Boiler safety system - temperature sensor, backdraft valve (it is needed to regulate the operation of the chimney);
• Heat exchanger.

Non-volatile system gas boiler must have open expansion tank, since when the coolant heats up, the liquid expands. And this is what promotes coolant circulation. But during expansion, excess is formed, which enters this tank.

Ignition in such gas boilers occurs using a piezoelectric element, which operates when a button is pressed. With its help, the pilot burner is ignited, and from it the main gas burner is ignited, thanks to which the heat exchanger is heated and the desired temperature of the liquid is maintained.

After some time, the gas does not flow and the burner goes out, after the heat exchanger has cooled down the process repeats.

Advantages and disadvantages of independent boilers

The main advantage of this gas boiler is the lack of connection to the electrical network. Since this is an additional saving and there is no need to connect an outlet.

It should be noted that these devices are easy to use. And also system security. This type of boiler is the simplest. And suitable for heating like small house, and large rooms.

Quiet operation of a dual-circuit device independent of electricity is ensured by the absence of pumps. Such devices are reliable and durable. This can be explained by the fact that such boilers have been produced for a long time and their operation has been tested in practice for more than one year. An independent boiler produces high efficiency. A double-circuit boiler easily provides desired temperature in the house and also hot water.

In such devices, the heat exchanger lasts much longer than in other models of gas boilers.

Let us note the disadvantages of such a boiler:

A gas boiler independent of electricity should only be installed in a house with good chimney draft. This is absolutely necessary for safe and quality work device. If the draft is insufficient, the fire will constantly go out due to the backdraft valve being activated.

If you have an independent gas boiler, the heating system does not always work as desired. For example, if you install pipes of the wrong diameter or do not calculate their desired location. All these factors are very important. It is better to design a heating system for a specific gas boiler, then there is a guarantee that no failures will occur.

Boiler operation

Since there is no access to electricity, double-circuit boiler there is a thermogenerator that stops the gas supply to the burner. This occurs when the heat carrier is exposed to the regulator. The automation resumes the gas supply to the boiler when the coolant cools down to a certain temperature.

Ignition occurs using a piezoelectric element, which ignites the ignition burner (it burns constantly) and, if necessary, the main heat source is ignited from it. It helps heat the fluid in the heating system.

Types of independent gas boilers

The following types of boilers operating without electricity can be distinguished:

• single-circuit– apply only to the heating system;
• double-circuit- these are devices that, in addition to heating, also provide hot water for household needs.

Dual-circuit gas boilers in turn, they provide hot water in 2 ways: flowing and storage.

Selecting an independent boiler model

Gas boilers operating without electricity must fully correspond to the area of ​​the heated room. That is, the power must match the load.

Double-circuit models from foreign manufacturing companies are often more expensive than domestic ones, since they are more advanced and have attractive design. The manufacturer of the gas boiler must be chosen carefully; it is important to ensure that service center This company is in the city or nearby. Since, if necessary, you can find spare parts for repairing the device there.

The most popular manufacturers similar equipment are Alphatherm, Beretta - Italy, Attack - Slovakia, Protherm - Czech Republic, Electrolux - Sweden.

Domestic models of independent boilers are cheaper than foreign ones, but are considered less reliable. But we should pay tribute that such devices are already adapted to our weather conditions and the parameters under which they must operate.

A gas boiler without electricity can be chosen with a steel or cast iron heat exchanger. The most popular are cast iron devices. This is explained by the service life: cast iron will last 30 years, and steel 15-20 years.

Cast iron is not only stronger, but the design also means that the walls of such a heat exchanger are thicker. This prevents the walls of the heat exchanger from burning through. This device has been tested in practice.

The heat exchanger may also be subject to corrosion. A cast iron appliance is much less susceptible to such damage than steel. Corrosion on the heat exchanger appears if the temperature drops to the point that condensation appears. And this very moisture leads to corrosion processes.

Also cast iron heat exchanger Its design consists of sections. If necessary, you can change a section, not the entire device. Nowadays, impurities are added to the cast iron alloy, which make it even stronger. This means that it will not crack if transported incorrectly.

Rules for installing a gas boiler

It is better to install a gas boiler independent of electricity in separate rooms with a good ventilation system, and also ensure air flow there. Because due to open chamber Combustion air is constantly “eaten” by the boiler. Combustion products are discharged through the chimney.

When installing a wall-mounted independent gas boiler, a coaxial chimney is installed, the design of which is called “pipe in pipe”. Coaxial chimney Not suitable for all devices and requires specialist advice.

If necessary, you can install circulation pump. Mount it via bypass. It is recommended to install taps near it: 1 at the entrance and 1 at the exit. A tap is placed separately on the main line, which must be closed when the pump is running. If such taps are available, if necessary, you can repair the pump without draining the water from the system. It is recommended to install a filter in front of the pump.

There are certain conditions that must be maintained:

• the boiler room must have a positive temperature;
• fire safety. The walls in the boiler room must be equipped with non-flammable material. As a rule, asbestos or metal sheets.
• The first start-up of the boiler after installation should be carried out under the supervision of a specialist.

A specialist should also check that the chimney is installed correctly. It is necessary that it corresponds to the power of a gas boiler without electricity and to the standards established by competent organizations. It's better for everyone heating device there was a separate pipe. According to the standard, the chimney should be straight; if it is impossible to make it this way, then there should be no more than 3 turns.

The length of the chimney should be about 5 meters. The heating unit must be selected and installed in accordance with the pressure in the gas pipeline, usually it is 1.270 MPa. The documentation that comes with the device (passport) always indicates the acceptable limits of this indicator. Sometimes gas pressure readings decrease in winter. Knowing this feature of the region, you need to select a device without access to electricity accordingly.

Terracotta clay has been around for a long time. Despite the fact that we use its Italian name (terra - earth, clay and cotta - baked), this type of clay has been used since very ancient times. It has been used by many cultures to make a variety of pottery and low-tech cooling devices for thousands of years. And all thanks to the porous structure of this material.

Wanting to create a natural air conditioner from terracotta, the company Ant Studio from New Delhi has designed a sculptural installation that can cool the air by passing small streams of water through it.

The exhibit was designed by Ant Studio founder Monish Siripurapu as a beautification project for an electronics factory. The design includes many terracotta tubes placed together in a metal frame in the form of a ring with a diameter of about 2 meters.

Siripurapu claims that traditional materials and design methods were used in the construction of the air conditioner:

“I'm an architect and I've always wanted to find a way to use ancient craftsmanship to create something that's environmentally friendly and aesthetically beautiful.”

The installation brings to life the idea that created an alternative to modern electric air conditioners. The factory management wanted to ensure their employees were healthy and comfortable conditions labor, but they could not afford a large cooling system. Therefore, the “terracotta” solution to the problem came in handy.

This exhibit works due to the fact that water flows over it (in this case, it is supplied there by a pump). Porous clay absorbs liquid, and as it slowly evaporates, the temperature of the air passing through these tubes decreases by 6-10 degrees. The use of cylindrical cones provides a large evaporation surface area to maximize the cooling effect.

Traditional materials and techniques hold a wealth of knowledge and opportunity, so modern designers look to the past as a reference point to solve the problems of the present and future.

Terracotta is another example of the hidden potential of these techniques. And, of course, its beneficial properties require further study. Clay is a rich material that has many advantages over artificial substances.

Moniz assures that the design of such bright terracotta air conditioners will only improve over time:

“I believe that this experiment has fully justified itself. The results that emerged from our first attempt revealed much greater potential. We now know how to work with technology that could change the way we look at air conditioning forever. After all, this is a truly important component of any building. Moreover, each such system can act as a work of art.”

If you want to disconnect from the centralized energy supply system or simply know that you are facing a power outage in the near future, you will be interested in learning how to live without electricity. Although to modern man It is difficult to imagine life without all the electrical appliances that play an important role in our everyday life; at the dawn of humanity, people were deprived of electricity. With determination, a positive attitude and a bit of ingenuity, you too can live without electricity for just one day or for the rest of your life.

Steps

life away from civilization

Part one: lighting and heating

Invest in alternative energy sources. If you plan to live without electricity, you will need to find other ways to power your home without the help of power companies. Renewable energy sources are in a great way do it. Install solar panels To harness the sun's energy, build wind turbines, power your home with a hydroelectric system, or install a generator.

Plan your lighting system. There are several options for how to best illuminate your home. One of them is a kerosene lantern. You can also use kerosene lamps, candles and led lights on batteries. You should also have a flashlight handy if you need to get up in the middle of the night and have no other light source.ref>

Prepare your home for winter. This means installing extra wall insulation, especially in the attic and around doorways. The heat goes under doorways, around windows and through the tops of the house. Create insulation systems that will allow you to lose as little heat as possible. Install flat threshold slats on bottom part doors. [ ]

Consider central heating. If you don't have a fireplace or wood stove, you should seriously consider building one. central heating, especially if you live in a cold climate. To heat the rest of the house, create outlets in the fireplace that lead to other rooms.

Part two: cooking

1. Think about how you will prepare the food. One of the best ways to cook without using electricity is with a wood stove. When the weather gets too hot to cook with a wood stove, you can replace it with a gas camp stove, which works in the same way as any other gas stove.

   Create a garden. Instead of buying fruits and vegetables from the store, why not grow them yourself? With just a few seeds you can turn your vegetable garden into a cornucopia. Plus, by growing your own food, you can be sure that your food is not exposed to any kind of contaminants.

   Raise livestock. if you have free space, try animal husbandry. Cows, goats and sheep provide excellent sources of milk, chickens provide eggs and meat, and raising pigs provides not only food but also compost for your garden. You can sell or store the food your livestock produces.

   Think about how you will store your food. An important part of life without electricity is Alternative option food storage, especially if you don't have a refrigerator. Almost all foods can be canned - from fruits and vegetables to meat and eggs. If you plan to make a lot of canned goods, consider purchasing home autoclave. Using an autoclave makes the canning process much more efficient.

Part Three: Other Basics of Living Away from Civilization

Make a compost pile. A compost heap is incredibly convenient, especially if you don't want to pay for city garbage collection. A compost heap can easily help you prepare it yourself. nutrients for fertilizing the soil.

Make your own fertilizer. This is especially easy to do if you raise livestock. Your garden will thank you if you feed it with your own organic fertilizer.

Focus on items that you could produce for sale or trade. Consider your skills: are you good at sewing, cooking, carving or construction? Determine what skill might be needed to produce goods in large quantities. Also consider what things you can make with what you already have. Are you involved in sheep farming? Learn to knit or make sheep's milk cheese.

Wash your clothes by hand. Although this may seem like a difficult task, in practice it turns out to be much easier. Dry your clothes on the washboard, rinse them, and then hang them to dry.

power outage

Part One: Preparing for a Power Outage

Prepare an emergency kit. In addition to water and food long-term storage, there are other basic items that should be in every family's emergency kit: a flashlight, spare batteries, universal tool(such as a Swiss Army knife), a hand-held can opener, a seven-day supply of essential medications and personal care items, extra cash, a portable radio, and an emergency blanket.

• Make copies of your personal documents. This includes important medical information, passport, proof of address and birth certificate. You should also have a map of the area and a list of emergency contacts.

1. Pack a first aid kit. You don't know in advance what might happen during a power outage or who might need health care. Therefore, it is highly recommended to have a first aid kit in your home. You can buy already equipped first aid kits or assemble your own kit. Think over a list of medications that will need to be added to your first aid kit.

   Store water in the house. The Red Cross recommends preparing at least 4 liters of water per person per day. If possible, stock up on enough water to last at least a week (so if you have a family of three, buy 21 liters of water).

   Stock up on non-perishable foods. These foods should be easy to prepare, or even better, if you don't have to cook them at all. If you don't have available source heat - such as grilling or camp cooking, which are described in part two - prepare mainly shelf-stable foods that do not require cooking.

   Keep an eye on your family members. If you find yourself in an emergency during a power outage, call your family members before your phone dies because you won't be able to charge it once the battery runs out.

   Keep some entertainment on hand. You will not be able to turn on the TV, computer or any other electronic device, so prepare your entertainment in advance. But keep in mind that it is better not to waste the flashlight’s battery power by shining a light on a book at night. If you have lanterns or candles, place one on a table so everyone in the family can read, play games, or chat.

Part two: lighting and heating

Invest in several alternative light sources. These include flashlights, LED lights and candles. Store flashlights in places where they can be found quickly in the dark. Candles are a great option because they burn for a long time without using up batteries. Flashlights are especially useful when traveling at night. You can also use a lantern to illuminate the kitchen while cooking.

Think about how you will heat the house. If you have a fireplace, stock up on wood. Close off rooms you don't use because what little heat you have will spread throughout the house. Also, consider purchasing a kerosene heater. Please note: Heaters must be placed close to a vent when operating, otherwise they may cause an increase in carbon monoxide levels.

Charge if necessary electronic devices using a car. If you can get out and go to your car, you can charge the electronics you need (such as cell phones for communication between family members and flashlights with a built-in battery). You can charge your electronics through a cigarette lighter that is connected to your car's battery.

Part Three: Cooking

1. Store perishable foods in the refrigerator. The best way The way to do this is to purchase a block of dry ice, wrap it in newspaper and place it in the refrigerator. Find out where you can buy dry ice in advance so you know where to go in the event of an emergency.

   • Open the refrigerator and freezer only when it is really necessary. You can also cover your refrigerator and freezer with thick blankets to keep the temperature inside them cool. Make sure blankets do not cover the vents of your refrigerator.

So, let's look at how a specialized powerful (designed for a load of 5 kW) uninterruptible power supply with 4 rechargeable batteries is constructed, which is more than enough to supply backup electricity to almost any country house.

And as a main test, we will boil water in an electric kettle using a UPS. Go!

A UPS is a device that allows you to convert D.C. from batteries to AC, which is necessary to power most household appliances and electronics. The peculiarity of such inverters is that, when powered by batteries, they provide alternating current with “pure sine”, which is very critical for consumers such as electric motors. In addition, an inverter of this class performs the functions of automatically switching to reserve when the mains power is cut off, and also functions as a mains voltage stabilizer if it goes beyond acceptable limits.

The UPS is very easy to connect to the network. I drew this diagram to make it clear how it works. In this scheme, a backup generator is not necessary and you can use the inverter without it. But the opposite, unfortunately, is impossible. That is, to automatically switch to backup power from a generator, you simply cannot do without an inverter in the system. The thing is that the backup generator cannot instantly supply current as soon as there is an interruption in the energy supply system from the external network. The generator needs time to start and warm up. And only after reaching operating mode can a load be connected to it.

The inverter in such a scheme is an intermediate link and allows, firstly, the generator to safely return to operating mode (by stabilizing the voltage), and secondly, ensures the continuous operation of all electrical appliances in the house when the power is switched from the mains to the reserve. Directly for the input switching itself, devices such as automatic transfer input (abbreviated as ATS) are used.

An inverter of this class is a fairly massive and heavy device. He weighs more than 50 kilograms. Such an inverter costs about 130 thousand rubles.

The inverter has 4 operating modes: normal (full backup and voltage stabilization), pass-through power with voltage stabilization function, just pass-through power and power off. If there is voltage at the input in any of the modes, the batteries are charged.

The inverter is very easy to connect. On the left we have terminals for connecting an assembly of rechargeable batteries with a separate switch, in the center there is a connection to the network, on the right there is a terminal for the load. At the top of the case there are two standard Schuko-type sockets for direct connection household electrical appliances. The entire terminal group is closed metal lid. In fact, the inverter must be connected to the gap electrical network after the introductory machine and electric meter.

50 kilograms is a serious weight, if not for the wheels, it would not be so easy to move the inverter by hand.

In uninterruptible power supply systems, it is necessary to use special sealed batteries made using AGM technology (Absorbent Glass Mat - electrolyte absorbed in glass fibers). Cheaper car starters lead acid batteries firstly, they cannot be used in residential areas (due to the release of harmful gases during charging), and secondly, they are not designed for a large number of deep discharge cycles.

To reduce losses in electrical circuit with such a high inverter power, the operating voltage of the battery assembly is 48 volts. Therefore, in our case, we make an assembly of four 12-volt batteries connected in series. The capacity of each battery is 100 Ah; such a battery costs approximately 12 thousand rubles.

Pay attention to the cable cross-section with which the battery assembly is connected. All inputs on the back of the inverter are closed plastic lids to avoid electric shock.

The UPS shown above is designed for complete uninterrupted power supply to a country house and, as I have already noted, its potential is maximized when used in conjunction with a generator equipped automatic start And automatic switch reserve. But inverters are also simpler, for example, for those situations when you need to automate the operation of the heating system during your absence and prevent the heating system from stopping (which can lead to freezing of the house).

For example, if you use a gas boiler and a liquid heating system (radiators or heated floors). Without electricity, not only the control electronics of the gas boiler will not be able to work, but also the pump that circulates the coolant in the heating system. That is, even if you gas heating- you cannot do without an uninterruptible power supply. For such cases, a simpler inverter is suitable, for example this one - designed for a load of up to 375 W. Usually a battery with a capacity of about 40 Ah is connected to it.

It is structured much simpler. For example, it cannot perform the functions of a voltage stabilizer, and among the settings there is only one switch that allows you to set the voltage range, when exceeded, it will switch to battery power. This choice is necessary if electric motors are connected as a load, and during startup there is a strong voltage drop. You can connect a refrigerator through such an inverter to avoid defrosting during power outages. In any case, such an inverter is usually designed to provide backup power to one or two devices.

And we move on to testing a powerful five-kilowatt inverter. I collected the most powerful ones in the house electrical devices, which will allow the inverter to be loaded to the maximum. Five kilowatts is a very serious load and I was very interested to see if the inverter could handle it.

So, for testing I took: a soldering iron for polypropylene pipes(1.5 kW), electric iron (1 kW), fan heater “Veterok” (2 kW) and electric kettle (2 kW). Fully charging rechargeable batteries And...

Having disconnected the inverter from the network, we begin to turn on the load!

Boil water in a kettle that is connected to an inverter with batteries?

No problem! And just as quickly as it happens when powered from the mains. At the same time, the soldering iron and fan heater were turned on. And the room became noticeably warmer (still, 5 kW of thermal power). At full load, this battery assembly will provide backup power to equipment for 20-30 minutes; less load - longer time autonomous work. If desired, the battery section can be expanded using several more parallel-series assemblies. But, as I noted earlier, first of all, the inverter must provide backup power at the moment while the electric generator is starting and warming up.

More details about how I boiled water in a battery-powered kettle:

You don't have to be Robinson to live in a house with no light. Unfortunately, even in the 21st century there are places where electrification and Ilyich’s light bulb have not yet reached. There may be many reasons for this, and I will not indulge in demagoguery, but I will tell you how you can arrange your life if the only resource you have is gas.

One of the most pressing needs of every person is food, and this is where household gas stoves come to the rescue. Modern technology adapted to all conditions and runs on both natural and liquefied gas. However, when connecting, you will have to do some magic with replacing the nozzles.

Several options are suitable for dacha and field conditions:

• stationary floor slab;
• portable tabletop stove;
• tourist portable stove;
• independent gas oven;
• frying devices - gas grill;
• single burner gas stoves.

Stationary floor slab

On the market you can find stoves with two, three or four burners, a worktop with an oven. Some manufacturers offer another interesting option– three-burner models with an oven and an additional compartment for installing a liquefied gas cylinder. Why vote with rubles?

The choice of the number of burners should be based on the volume of daily cooking, – and start from this. However, if you just need a floor stove, I advise you to go with a regular four-burner device. You will not be limited in the amount of food you prepare, and this is convenient. Any saucepan, cast iron, bowl of jam will fit here without any problems.

All spilled food will be collected on the stove table, which also serves as a tray. Pots will securely hold enameled or cast iron grates, but if you want to save money, you can also use a rod version.

On the issue of functionality

According to GOST, functional slabs are called slabs with increased comfort.

The following works here:

• Ovens have not one, but two burners– lower and upper (gas grill). I think it’s worth paying for it, especially if you are looking for equipment for your permanent home;
• combustion mode is supported automatically– This is a thermo-electromagnetic valve, a thermostat. Both are quite useful and worth the money. The thermostat maintains the temperature in the oven. Valve – controls the presence of flame on the burners;
• temperature control is smooth, not stepped. This always works to its advantage.

I'll tell you straight, Various types gas stoves, both expensive and budget, are characterized by a general technological scheme. More high price you pay for large quantity burners, oven design, power and additional design features. But there’s no need to be too clever. In practice, the capabilities of 4-burner stoves, with traditional cleaning and embossed guides, are quite sufficient. I have listed the options that are worth paying for above.

Pay attention to manufacturers such as Hephaestus - Belarusian slabs are very close to our reality, there are good options Gorenje,Bosch,Hansa,Kaiser, Lysvensky plant(famous “Lysva”). The price starts from 8 tr.

Portable tabletop gas stoves

Tabletop stove is best option For country house, especially if you are not inclined to bake pies. The power source is no different from stationary stoves - it is a classic gas cylinder or main gas. I note that the continuous operation time of the device depends on the volume of the cylinder (options are available for 5, 12, 27, 50 l).

In terms of external design, the work table of such plates is identical to stationary ones. The number of burners can be different: one, two, three, four. There are steel grates above the burners - these are typical solution for this class. Most often, an enameled desktop coating is implemented.

I would recommend not to philosophize and take a standard two-burner model. It’s not for nothing that this type of stove is called portable; most weigh no more than 1.5 kg. This greatly simplifies transportation and carrying. Control – mechanical, with rotary controls. Smooth temperature adjustment is welcome. If two burners are too much, the most compact single-burner tabletop stoves will help out.

Features of choice

Let me remind you that all of the equipment listed is compatible with both main and liquefied gas. But, when buying, pay attention to nominal pressure, specified in technical specifications. This, by the way, applies to all gas stoves. Check the kit, even single-burner models can be equipped with connecting fittings: hose, adapter, gasket, clamps, replaceable nozzles. Equivalent power from 1.7 kW is sufficient.

Manufacturers you can trust: Zlatoust Machine-Building Plant(table plates “Dream”), Hephaestus,Gorenje. average cost– from 600 rubles for one burner.

Tourist portable gas stoves

Portable gas stoves are a good alternative to the two previous options. The advantage is that they are taken not only to the hacienda, but also on hikes, fishing, etc. It turns out that you can kill two birds with one stone. The stove can be easily moved from corner to corner and used even on a table, even on a terrace or veranda.

These are compact and lightweight devices equipped with one burner. Most of them are square in shape. Weight does not exceed 500 g, dimensions – 10-25 cm. The body of the portable stoves is metal, which is a good contribution to reliability. Manufacturers make burners based on ceramics or cast iron. Both options are quite stable and will not let you down.

How it works

The stove is powered only from a disposable gas cylinder. The cylinders themselves differ in the type of fastening - valve, pierced, threaded, collet. In mobile devices, the collet type is more often used. In short, a mixture of isobutane-propane-butane is charged here.

The quality of combustion depends on the quality of the mixture, especially if it’s below zero outside and the house is unheated. Therefore, I advise you not to save money. By the way, if you visit your dacha in winter and plan to cook, it is better to have a canister with propane pumped to 50% or higher. Typical capacity is 220 g. This is enough for two hours of continuous operation. If you translate into a day, that’s two days, essentially a weekend. However, I advise you to always keep one or two cylinders in reserve.

The only caveat is that the simplest mechanisms cannot regulate the strength of the flame. In fact, such a primitive device can only be turned on and off, but the type of ignition is the same everywhere and this is piezo ignition.

If you need adjustment, please note models of portable stoves with a special compartment into which a disposable cylinder is inserted. Here the intensity of combustion almost always varies, for which a rotary knob is provided. However, this will immediately affect the price.

Selection factors

To keep the cookware firmly on the stove, you need to choose devices with sliding metal blades. When folded, they do not affect the dimensions of the stove, but when assembled, they increase the working surface. If you plan to use the device on the terrace or, say, on a table near a bed of herbs, take equipment with protection from the wind. It definitely won't hurt. Essentially, it is a metal dome placed around the perimeter of the burner.

I can recommend several manufacturers that provide consistently high quality - these are "Pathfinder"Kovea,Irit. Average price – 670 rub.

Autonomous gas oven

Independent ovens Mostly built-in. This is, of course, not entirely country option, but for a country house it’s just right. main feature What makes such models so popular all over the world is that they can be installed in any convenient place, including at chest level. You can take a separate oven and a compact portable or tabletop stove, creating the most convenient option for yourself.

I won’t go into too much detail; the functionality of the equipment is identical to floor-standing ovens and is produced by almost the same manufacturers. However, you can play some magic with the design and dimensions. Overall, I would recommend taking the brand Hansa. In this segment, it still wins in terms of quality, functionality and price. The average cost starts from 23 tr.

Gas grill

This is a rather expensive thing, mainly, it is positioned as a more convenient alternative to charcoal barbecues. In fact, this is true. The device heats up very quickly and is ready for use within a few minutes after switching on. No skill or coal is required for ignition. But another thing is important - you you can control the temperature very accurately, the burners make it possible to regulate the mode, which is relevant for frying different types products. The only objective disadvantage of gas grills is the price.

Selection factors

Present on the market gas grills of three categories: portable, built-in, tourist. Built-in models are not the best option; this is equipment for grill restaurants and professional kitchens. However, they are sometimes purchased by owners country houses, where there is a centralized gas supply. These are high-performance grills that are worth taking if you have the money and value in this very performance.

So to speak, portable models can be called the golden mean. For convenience, they are placed on trolleys with wheels; there is also space for a gas cylinder and additional accessories. Compact ones are suitable for picnics, weekenders, and small families.

What to consider when choosing:

• The surface of the frying panel can be smooth or corrugated. The first is suitable for fish, vegetables, hamburgers, the second - for all meats. If you need a compromise, take a grill with two types of surfaces. Immediately pay attention to the grates, which have a noticeable impact on the quality of the dishes. The best option– wide frequent rods, material either steel, or stainless steel with porcelain coating, or cast iron;
• number of burners is a performance issue. When there are several of them, you can cook 2-3 dishes at the same time. A one-piece grill is suitable for grilling steaks and sausages a couple of times a season. Take a device with several burners made of cast iron, brass or stainless steel. Lids should be made of thick steel or stainless steel. Porcelain enamel is welcome. I note that reputable manufacturers always provide a guarantee on burners for up to 25 years;
• additional options. The simplest models can only fry. More extensive functionality is a smokehouse and spit. Whether it will be useful on the farm is a personal matter for everyone;
• adjustments. We can say the following: note that the best results are obtained by smooth rather than stepwise temperature control;
• ergonomics. One thing is important - the device must be stable. Good grill will not rattle, wobble, or sway. The lid should open effortlessly and smoothly. If there are wheels, they must be able to be fixed and run smoothly;
• most important point – power. The manufacturers that I will discuss below designate power in thermal units - BTU. This tells you how much gas the grill takes in and how much heat it generates. Typical settings range between 10,000-60,000 BTU/hr. However, this is not the most important thing. The point is that you need to correlate the power with the cooking area. Get a grill that has at least 16 BTUs per cm2.

Manufacturers you can trust: Napoleon,BroilKing,Weber,Landmann, – here you can find European full-size, built-in, portable grills excellent quality. Compact models look at Cobb. This brand produces gas grills that look like saucepans. However, appearances are deceiving - these things can deliciously fry, smoke, bake like an oven, stove and steamer!

If we talk about price, I would not recommend saving. If you need a gas grill, get one that will last for centuries and that your grandchildren will get, you won’t regret it. For a device with good European assembly, you can pay at least about 40-55 thousand rubles. Large specimens cost 100 thousand rubles, with four burners - 160 thousand rubles.

Single burner gas stoves

It was not for nothing that Sharikov was fixated on primus stoves; previously, these simple devices were part of any communal apartment and ran on kerosene. The downside is that the nozzles of such burners quickly become clogged and they smoke shamelessly. However, V modern models gas is used as fuel and such problems were avoided, at least they arise quite rarely.

In principle, these devices are quite convenient and can be used for cooking in the country. The startup procedure takes seconds. The operation of the kerosene stove is practically trouble-free, quiet, and the instructions for use are extremely simple and there is no need to waste your nerves. Another plus is that single-burner models are not prone to flames and explosions, which is so typical for gasoline-powered comrades.

How it works

The burner is mounted on a gas cylinder. The regulator opens the fuel supply, you light the burner and cook food. The downside is that you will partially heat the air. The efficiency of gas stoves does not exceed 60%, but this problem affects everyone to one degree or another household appliances. But all burners with cylinders are distinguished by their mobility, light weight and decent power - there is a choice of both 1200 and 3300 W.

The main trump card is the price. A good burner can be found for 1-2.5 rubles, plus a gas cylinder costs about 250 rubles. In total, you can fry potatoes, cook dumplings in the country and in other field conditions for only 1.5-2.5 tr. Good gas stoves can be found at brands KOVEA, Pathfinder, Belarusians have worthy examples. But, this is a temporary option after all, so to speak, a compromise before purchasing serious equipment.

Selection factors

Choosing a burner pay attention to its diameter, it depends on it thermal power . As practice shows, 16.5 cm is enough. For long-term trips, it is better to take a larger gas cylinder - 5 liters; for a weekend getaway, a mini-can will be enough. They are designed for reusable use and can be refilled again and again.

Storing food in gas refrigerators

Surprisingly, Such refrigerators are considered environmentally friendly. To begin with, I note that they can work both from electricity and from gas. There are units that appearance bear little resemblance to traditional refrigerators. Essentially, these are metal boxes with a lid that contain one or two cameras inside. However, you can search for more traditional form factor - gas mini-refrigerators. Structurally, they consist of several elements: heater, generator, evaporator, absorber, condenser.

How it works

The equipment is connected to the gas cylinder through a fitting. Practice shows that one cylinder is enough for a month of work. Operating principle: the gas burns, the mixture of ammonia and water is heated, and the device cools. It is ammonia that acts as a refrigerant, and water acts as an absorbent material.

So, the gas brings the ammonia-water mixture to a boil, and the boiling point of ammonia is lower than that of water. So the gas gives off concentrated vapors that go to the heat exchanger, evaporator, condenser. When the vapor leaves the evaporator, it comes into contact with the absorbent and is cooled. This entire cycle goes on continuously.

Heat exchange is realized through the rear grille. When the appliance is in operation, condensation forms and is drained. There is a refrigerator inside and freezer compartment. Defrosting is manual and is carried out once every 2-3 weeks. The temperature inside the refrigerator compartment varies within +2-4 degrees, in the freezer it reaches -5-15 degrees.

A few words about functionality

Refrigerators of this type are able to operate uninterruptedly from a standard gas cylinder, the main thing is to fill it on time. After turning off, the machine can maintain the set parameters for some period. There is a temperature control function.

Liquefied gas provides high productivity and energy efficiency. The trick is that There is no compressor in the design, which eliminates noise and vibration. The latter, by the way, greatly affects the wear of the main components of electric counterparts; there are no such problems with gas.

By the way, there is also lighting inside the gas refrigerator. This LED bulbs battery powered lighting. The charge will last for about a year, which is a lot.

Selection factors

If you search, you can find units of almost any size and capacity. In general, the selection principles correspond to electrical analogues. If you need to save a small amount of supplies, you can take a mini-model with a volume of up to 35 liters. For living throughout the summer season, larger models are suitable - 100 liters and above. I note the most compact samples do not have a freezer, this point should be taken into account.

Please note that gas refrigerators also have a climate class. SN-ST is considered universal. When you need maximum capabilities, take equipment with automatic defrosting, super cooling/super freezing, you can look for devices with antibacterial coating, light and sound indication. The control type can be either electronic or mechanical, but I would recommend choosing last option, – it will last for half a century and will not cause unnecessary headaches.

Installation nuances

As I already said, gas refrigerators run on propane and are connected via a hose through a reducer to a fitting. The machine can stand anywhere, the main thing is that it is stable and level. I would like to draw your attention to the fact that back wall The refrigerator produces heat and is capable of heating nearby objects and surfaces. The heat generated is much greater than that of its electric counterparts. Do not place equipment close to a wall or a silk curtain - it will burn.

The installation itself is somewhat reminiscent of connecting a gas stove. To operate, a hose with a reducer is connected from the cylinder to the fitting. If required, you can switch the work to electricity by plugging the plug into the outlet (the heating element will begin to provide the temperature). The cylinder is then disconnected. Caring about safety, it is advisable to take a device equipped with automatic system gas disconnections. If problems are detected with the burner, the system is activated and cuts off the fuel supply.

And lastly, if there is gas, good ventilation is necessary. Too harmful for the device high humidity and dustiness.

Briefly about the manufacturers

I won’t say that gas refrigerators are widely available. You may have to purchase equipment to order. I advise you to pay attention to the devices from Exmork. The brand produces both compact and full-size devices and refrigerated chests. Interesting models with mechanical control can be found from the company Vitrifrigo.

The price of the equipment is quite high (and this is against the backdrop of lower efficiency than that of electric comrades), miniature copies are available for 250 USD. and higher, which is somewhat mitigated by availability gas fuel. But this is a price to pay for comfort given the lack of electricity supply.

What's the result?

If you don't have electricity, but have gas, don't despair. You can cook food, warm tea, and preserve food without this; fortunately, manufacturers are generously filling the gas kitchen appliances segment. The optimal set is a refrigerator and a stove. But what they will be is up to you to decide, taking into account the size of your family, length of stay in rural areas, budget.
