Bosch geysers. Bosch instantaneous water heater. Bosch geyser: review of models and prices Gas instantaneous water heater therm 4000 0

After German company Bosch began to produce geysers under its own brand, and the products firmly began to occupy a leading position. A special feature of the company’s geysers is their completely “white” assembly. And, as you know, European quality valued all over the world for its reliability and durability. All this imposes an obligation on the company to provide customers with a long warranty period (2-3 years) for its equipment.

I would especially like to pay attention to the line of geysers WR-13, which was created specifically for two gas supply systems - stationary and bottled, operating on liquefied gas. In our conditions, none of the above methods of gas supply can be neglected. Thanks to this gas supply range, the system has high protection from changes in gas pressure and overheating.

In this line there is a type of speakers WR 13-2, which has proven itself to be multifunctional, lightweight, small in size and undemanding to installation conditions.

In particular, this type of column is divided into three subtypes depending on the starting system: P - piezo ignition, B - auto ignition and G - hydrogenerator.

The advantages of geysers WR 13-2 are the presence in them:

• components from Europe, including assembly;

• main elements made of stainless steel, including burner nozzles;

• flame and air draft control;

• water flow regulator;

• safety overheating;

• ionization control of the fuse.

Bosch WR 13-2 is designed to simultaneously heat water for washing dishes and taking a shower. The device allows you to pass water through itself with a productivity of 13 l/min, heating it with a power of 22.60 kW.

Possessing high performance, WR 13-2 has very small dimensions of 66x35x22 cm (HxWxD) and an acceptable weight of 13 kg.

The device allows you to increase the temperature by 25 degrees from initial temperature water with a productivity of 13 l/min. or 50 degrees - with a capacity of 7 l/min. Price model range WR 13-2 ranges from 9,000 to 13,000 rubles.

In order for the device to be installed at home, it must have a chimney with a diameter of 13 cm.

Due to the fact that the geyser can not only operate from a stationary gas supply, but also from a bottled one, it can be used both in urban conditions and in country apartments.

By installing WR 13-2 in your room, you will forget about the time when you felt discomfort from the absence hot water, and you will no longer have to pay monthly utility bills for expensive hot water.

Compactness, safety, quality and durability of the WR 13-2 will allow you to enjoy the comfort of using this device.

And finally, starting to produce geysers, Bosch company made sure that every regional city had its service center for servicing geysers, so by purchasing the WR 13-2 model, you not only insure yourself against malfunctions, but also provide the necessary preventative maintenance to the device.

So, by purchasing WR 13-2, you embody the motto in your life: “Let the water desired temperature It’s pouring, but the device doesn’t fight!”

The Therm 4000 GWH 10/13 model (water heater) is offered in three modifications, differing in their performance characteristics.

It is 27% more compact than its predecessor and is the most compact in its power category.

The main advantage is increased safety: if a fault occurs, for example in case of insufficient air supply, our gas water heater automatically switches off the device and, thereby, provides protection.

The minimum water pressure to turn on a water heater with piezo ignition and battery ignition is 0.1–0.2 atm. At the same time, the device operates stably and produces hot water at a constant temperature.

All modifications are equipped with a flame modulation system, i.e. automatic change power depending on water consumption. For the user, this means a constant water temperature regardless of its consumption.

A characteristic feature of this gas water heater is the developed technology that ensures safety.

Even with insufficient draft, flue gases will no longer flow back into the living space. The latest Anti Overflow System reliably ensures the removal of combustion products through the chimney.

Also, all models of the Bosch 4000 geyser are equipped with: flame control, which turns off the gas supply if for some reason the flame goes out; overheat control, which turns off the device if the heat exchanger overheats.

Ignition of the igniter by simply pressing buttons. To ignite the igniter, you need to press the ignition gas valve opening button with one hand, and the piezo ignition button with the other.

An electric spark created by the piezoelectric element ignites the pilot burner. After the flame appears, 10–15 seconds. you must hold down the gas valve opening button.

During this time, the thermocouple, which controls the presence of the flame, heats up and, using an electromagnet, keeps the gas valve open.

The water heater is ready for use. The power of the water heater is changed by the position of the slider, and the water temperature is changed by the position of the rotating knob. If the filter is clogged tap water it can be easily removed and washed.

Minimum possible pilot gas consumption - Gas consumption by a constantly burning pilot flame in water heaters is reduced to the minimum possible.

The pilot burner nozzle is precisely designed to ensure that the flame burns steadily and can ignite the main burner.

Before installation, obtain permission from the gas supply company and from the department for cleaning and checking the condition of chimneys.

Place the gas shut-off valve as close to the appliance as possible.

After connecting to the gas supply network, it is necessary to check the connection for leaks. To avoid damage to the gas fittings due to increased pressure, pressure control should be carried out with the gas valve closed. After checking for leaks, release the pressure.

Check whether the type of gas indicated on the type plate matches the type of gas supplied.

Make sure that the flow and pressure at the gas pressure regulator correspond to the values ​​​​specified for the consumption of the device.

Installation room requirements:

The device cannot be installed in rooms with a volume of free space less than 8 m3, excluding the volume of furniture, if this volume does not exceed 2 m3.

Observe local regulations.

The installation room must have good ventilation and frost protection, as well as the possibility of connecting to a chimney.

Do not install the device above heat sources.

To avoid corrosion, the combustion air must not contain aggressive substances.

Corrosion is promoted by hydrogen halides containing chlorine and fluorine compounds. They may be contained, for example, in solvents, paints, adhesives, aerosol sprays and household cleaners.

The minimum distances shown in Figure 3 must be observed.

Chimney

All gas instantaneous water heaters must have a sealed connection with flue gas exhaust pipes of the appropriate diameter.

The chimney must:

– pass vertically (with little or no horizontal sections);

– be thermally insulated;

– have an outlet above the highest point of the roof.

To connect to the chimney, you can use a flexible or rigid pipe. The flue gas exhaust accessory must be inserted into the flue gas protection manifold.

Outside diameter The flue gas exhaust accessories must be slightly smaller than the size of the flue gas protection manifold.

A canopy must be installed at the chimney outlet to protect from wind/rain.

Installation work for a Bosch 10/13 geyser:

Operating principle

The instantaneous water heater (gas water heater) is equipped with a piezo ignition device. This makes operation more convenient.

Power regulator from the Off position. move to ignition position.

Press and hold down the power control button. Press the piezo ignition button.

If the pilot flame lights up: after a few seconds, release the power control button.

If the pilot flame goes out: repeat the process.

In this case: Keep the power control button pressed until the gas supply pipe is completely free of air.

If ignition occurs: move the power regulator to the right to set the required power.

Using the power regulator you can set the required power. As the regulator moves to the right, power and gas consumption increase. Maximum power is achieved when the regulator is set to the extreme right position.

To save energy: set the power regulator to a position that fully corresponds to the required power.

Once these steps are completed, the main burner lights up automatically as soon as the hot water tap is opened, as the pilot flame burns continuously.

To turn off the device: move the power control to the left until it stops. After a few seconds the pilot flame will go out.

I have lived my entire life in an apartment with a water heater and I know all their pros and cons. Only the speakers were the simplest (Soviet cast iron and Astra). And finally, I have a new BOSCH speaker!!!

Price 9900 rub. as of January 12, 2015, but I know that it is constantly growing.

VISUAL INDICATORS:

1. It is smaller than Astra, and its exhaust pipe diameter is smaller. Dimensions (HxWxD), mm 580x310x220, weight 11 kg.
2. The wick is VERY small, almost does not heat the water, the gas control sensor is needed.

   During the day you can’t even see how it’s burning.

   Why “everything that was previously impossible is possible.”

   1. The small wick does not heat the water (immediately after turning on there is no boiling water, no need to drain, the water does not boil away and scale does not form that clogs the column).
   2. You don’t have to turn on the water fully and not be afraid that the water heater will go out (this way you can regulate the pressure and temperature of the water).
   3. You can turn on both water taps (hot and cold) at the same time; the column does not start to hiss and go out.
   4. Excellent pressure allows you to turn on the water both in the kitchen and in the bathroom (previously the pressure was only enough for one thing).

   Why "no savings".

   The problem we had was that the cold water pressure was good, but there was only a thin stream from the water heater, and the water heater barely lit up. And now I turn the water on only halfway and that’s enough for me. So now my water meter is shaking like crazy((((

   Another plus I would like to note is the presence of gas control, a water filter, and an overheating sensor.

   
   Very comfortable andneat appearance of adjusting water pressure and temperature.

   
   

   For those who understand this

   

   

   

   

   The installer of the speaker (called from the store where it was purchased) after careful questioning admitted that there could only be one problem with it. Once every two years it is advisable to clean it from dust (the column is designed in such a way that a draft is formed in it from bottom to top and therefore dust, fluff in the summer, etc. is retained inside). But this is only if it starts to ignite poorly. In all other respects, he said that this particular model is the most perfect option, nothing extra and not expensive!!!

   I'm really happy! Well, unless of course you count the increase in water consumption)))))

Bosch geysers (this is the common name given to instantaneous water heater) - a device in which cold water, flowing through the tubes around the heated heat exchanger, it is heated and supplied to the consumer at a given comfortable temperature. Bosch geysers heat water using energy obtained during gas combustion.

At the end of the 19th century, the designers of the Bosch concern first designed a gas water heater. The device has undergone numerous modernizations over time and in our time represents a fully automated product, which is still in demand in households where, for a number of reasons, there is no centralized supply of hot water.

Today, instantaneous water heaters are produced by companies all over the world; Bosch is rightfully considered the leader in the production of these products. The Bosch concern offers the consumer a wide range of devices with different power characteristics that can satisfy all the homeowner’s needs in heating the required volume of liquid.

Modern Bosch geysers are capable of heating water online. The owner does not need to waste time waiting for the required volume of water to warm up. The instantaneous water heater is stuffed with all kinds of sensors and valves that allow you to receive comfortable temperature at the water point. Bosch geysers, regardless of model, are equipped with power modulation.

Thus, as water consumption increases, the heating intensity automatically increases. If the consumer reduces the pressure by closing the tap, the burner automatically reduces the flame, reducing the intensity of work. The main advantage that unites Bosch geysers is energy efficiency and cost-effectiveness, which result in significant financial savings in the form of gas bills.

Before we begin our review of the Bosch instantaneous water heater, we suggest you decide on the necessary parameters of the device that are suitable for you. There is no need to buy a Bosch geyser with a “reserve” of power; this will only lead to high initial costs and subsequent excess consumption of gas and, as a consequence, financial resources.

On the other hand, the choice should cover all needs for hot domestic water consumption. We told you how to choose a Bosch gas water heater twice, this and the second time, in them you will find seven answers to basic questions.
