Gas instantaneous water heater therm 4000 0

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 pressure cold water good, but there was a thin stream from the column, the column barely caught fire. 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 convenient 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)))))

Geyser Bosch Therm 4000 GWH

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.

On the market household appliances It's probably already hard to imagine trademark better known than Bosch. The company quite successfully supplies products under its brand all over the world, ranging from irons, refrigerators and ending with power tools. A separate division is production by a German concern heating equipment: boilers and water heaters from Bosch Thermotechnics.

Solid fuel and already long years heat houses, both in Russia and abroad.
They are especially popular among Russian consumers Bosch geysers, reviews of which can often be seen on specialized websites. Buyers are attracted by quality and reliability at affordable price for instantaneous water heaters from German manufacturer.

Let's figure out together whether a Bosch gas water heater is worth buying today, given this wide choose manufacturers nowadays. To do this it is necessary to consider the lineup, prices and specifications device from a German concern, disadvantages and advantages compared to its direct competitors on the market.

Let's do a short review geysers Bosch based on the operating instructions, as well as reviews from specialists and customers. Let's analyze the main malfunctions of the Bosch column: why the pilot light does not light up or the wick goes out, etc.

Model range and features of Bosch geysers

Bosch geysers, unlike their direct competitor, have a very wide range of models. Many modifications with different types ignition and performance, design and size. Water heaters are available in two colors: white and gray.

Bosch geysers: model range


All gas instantaneous water heaters are assembled in Portugal, the only difference is one, the most budget model of water heaters - “Therm 2000 O”, type W10 KB, which is assembled in China. Now let's look at all the models and series that are supplied to the Russian market.

1. Series Therm 2000 O

This is a budget geyser with a small hot water output of 10 l/min. This unit is equipped with automatic battery ignition, a tubular copper heat exchanger and gas burner made of stainless steel.

As in the columns, it contains an emergency draft and flame control sensor, as well as a water temperature sensor and a gas control system. The Bosch W10 KB speaker is compact in size and can be purchased inexpensively, starting from 8,000 rubles.

2. Series Therm 4000 O

The most popular models are available with both automatic ignition from batteries and piezo ignition by pressing a special button. Three types of different power and productivity from 10 to 15 l/min are available. Bosch geysers in this series have a high-quality copper heat exchanger for heating running water with an increased service life of up to 15 years.

Also, these models are equipped with smooth modulation of the burner flame, with the help of which the device itself maintains the set outlet water temperature. An important advantage of this model is that this column turns on at a water pressure of only 0.1 atmosphere.

Flow-through gas water heaters this series have the following designation:

— Bosch column with automatic ignition (article “B” is present): WR 10-2B, WR 13-2B and WR 15-2B;

— Bosch semi-automatic column with piezo ignition (marked with the symbol “P”): WR 10-2P, WR 13-2P, WR 15-2P.

Bosch column with piezo ignition


3. Series Therm 4000 S

The main feature of this model is the presence of a fan for forced draft. These speakers can operate without a chimney, i.e. no special construction is required. This feature very convenient when it is not possible to install a chimney in an apartment or house.

The release of combustion products and the flow of air into the gas water heater is carried out thanks to a special one, which is installed horizontally through the wall to the street. This kit is an option and is supplied separately from the device itself.

One more important feature Bosch geysers of the AM1E series is the presence of a digital control panel on which the possible mistakes in case of device malfunctions. You can also set the water temperature and, thanks to even smoother and more precise modulation of the burner flame than the previous model, this water heater will maintain the temperature with an error of only 1 °C.

The model is available with three types of power, with a capacity of 12 to 18 l/min. Unlike other models, this series of devices is energy-dependent due to the built-in fan, powered by a 220 V network. They are labeled as WTD 12 AM E23, WTD 15 AM E23 and WTD 18 AM E23, depending on their rated power.

Gas water heater Bosch "automatic" with closed camera combustion


4. Series Therm 6000 O

The Bosch 600 series geyser is equipped with a built-in hydrogenerator. Automatic ignition in this model is carried out thanks to the flow of water through the column. When you open the tap, water flows into the water heater, and HYDRO POWER technology automatically turns on the gas water heater through a special hydrodynamic generator.

To ignite the device, neither a piezoelectric element nor batteries are required. Available in different capacities: 10, 13 and 15 liters per minute. They have the abbreviation WRD 10-2G, WRD 13-2G, WRD 15-2G, the numbers show performance.

The control panel has a small LCD display that only displays the water temperature. This parameter is set using a mechanical regulator on front side speakers and is supported by the device automatically.

5. Series Therm 6000 S And 8000S

These are industrial models of geysers from a German concern. The productivity of water heaters of these series is 24 and 27 l/min, respectively. These speakers are capable of supplying hot water 4-5 water points at the same time. Bosch water heaters are equipped with electric ignition and an informative LCD display on the front side.

The 6000 S series model has two built-in fans to remove combustion products and suck in air. Bosch 8000 S water heater thanks to special technology condensation has increased water heating efficiency. In addition, the water valve of this model is equipped with an electric drive.

The operating principle of a Bosch gas water heater with piezo ignition is quite simple. Set the water temperature regulator to the “On” position, press the button of this regulator, while simultaneously pressing the piezo ignition button from below. Hold down the thermostat button until the speaker turns on. We ask them desired temperature water.

The principle of igniting a gas water heater with automatic ignition is even simpler. We open the hot water tap on the mixer, and the column turns on itself, thanks to the batteries pre-installed in the device. Bosch gas water heaters come complete with a water heater. The pilot light for devices with piezo ignition is constantly on, but for automatic speakers it goes out when the device is turned off.

Technical characteristics of geysers Bosch WR series

Water heaters from a German manufacturer can operate on both natural and liquefied gas. The diameter of the gas supply pipe is 3/4 inch, water – 1/2. The diameter of the chimney pipe varies and, depending on the specific model, ranges from 115 mm to 135 mm. Other parameters can be seen in this table.

Malfunctions and repairs of a Bosch gas water heater

1. The pilot flame goes out or the column does not light up the first time.

The pilot burner needs to be cleaned.

2. The igniter goes out or the wick goes out when opening the tap on the mixer.

Check the pressure if the dispenser runs on liquefied (cylinder) gas.

3. The water coming out is not hot or cool enough.

Check that the temperature regulator on the column is set in the correct position.

4. The pilot light goes out periodically.

The draft or water temperature sensor may be triggered. You need to call a specialist to fix these problems.

5. Poor water pressure through the column.

Either the heat exchanger of the column or water unit, or the mixer is clogged. Identify the source of the blockage and clean it.

6. The automatic dispenser does not turn on (does not light up).

Check the condition of the batteries. Replace them with new ones.
