Bosch geyser is not. Gas instantaneous water heaters (geysers)

Bosch geysers (this is the common name given to instantaneous water heaters) - a device in which cold water, flowing through tubes around a heated heat exchanger, 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 that is still in demand in households where, for a number of reasons, there is no centralized supply 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 uniting 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.

Now it's time for another representative geysers Bosch. Distinctive feature Bosch gas water heater from other water heaters, this is a set simple functions, which the speaker from the manufacturer Bosch has, making it easier for the consumer to use.

It should also be noted that this manufacturer produces only high-quality products and is constantly improving in the consumer market. The manufacturer constantly introduces high-tech innovations into this geyser.

1 Review of Bosch gas equipment

The Bosch geyser works by heating running water. We all know that this manufacturer has in its assortment many models that can serve for different purposes.

They can be used in a private home, production, factories, kindergartens, social homes and other facilities. For example, the Bosch w10 kb geyser has a reliable a heating element, nice appearance and simple controls.

Has high safety and high power. This model also has a high degree of efficiency in heating running water.

Types of Bosch geyser:

Battery-powered geyser design. How does this gas appliance work? The burner is ignited using electric ignition, and a special electrode supplies the spark.
Bosch geyser with piezo ignition. The igniter is lit with the help of the consumer mechanically, that is, turning on the button by a person. The column begins to heat the water after the consumer opens the hot water tap.
A gas water heater that can be paired with a hydrogenerator. This principle works the same as with batteries, but here the spark is generated using a hydrogen generator.

There are also many more ways in which gas equipment of this brand works. Good feedback received a Bosch geyser running on liquefied gas, which can be supplied from a gas pipe. As we know, the gas pressure in the pipeline is sometimes not constant, and the manufacturer when making the columns took this shortcoming into account.

It should be said that each geyser is equipped with a copper heat exchanger, and as we know from the heat exchanger good quality The operation of the column itself depends. The heat exchanger for a Bosch geyser is made of copper, which is why this device is efficient in operation.

2 A little history about the manufacturers Bosch

Robert Bosch GmbH launched production 125 years ago. For this long haul the company has become a brand. This brand produces not only gas equipment, but also small household appliances.

The company is known for producing spare parts for cars, household appliances, and home appliances. This category is also known for the production of garden tools. There are many stores of this brand open all over the world. Any large supermarket has departments household appliances Bosch brand.

It should be noted to those consumers who own geysers that a Bosch geyser service center is located in almost every district and city, which significantly helps consumers of this product.

When purchasing appliances, either Bosch gas water heaters or garden tools, you will always find a service in any city, a store where specialists will help you. They will always advise, tell you the pros and cons and help you make the right choice.

2.1 Common models of Bosch geysers

Let's consider the Bosch wr 10 geyser, which differs from others in that it has a huge selection of different designs and functionality. It is suitable for both a private house and an ordinary apartment.

The Bosch wr 10 geyser is much better and newer than the Bosch wr geyser. Both columns are equipped with a good security system, which no gas appliance can do without now. It also contains increased level quality of combustion products emissions.

As mentioned above, all geysers from this manufacturer have a copper heat exchanger, and the maximum output power exceeds 18.5 kW. Is not bad option for family. The prices for Bosch geysers will please you. The simplest low-power speaker will cost you from 6,500 thousand rubles.

Another option that you can choose is the Bosch wr 13 gas water heater or the Bosch wr 10 gas water heater. Their maximum power reaches 17.5 kW. This design has a type of ignition called piezo ignition.

Switching on occurs by pressing a button by the consumer. By pressing the button, the wick ignites, which ignites the burner. A distinctive feature of this burner is that it can independently regulate the flame level, and this is an important point.

This also affects the water pressure. As a result of all this, the Bosch wr 10 geyser can independently maintain the temperature regime. And as we know, the gas pressure in the pipeline is not always constant. The manufacturer took this into account when producing gas appliances.

Also, the water pressure in the pipes may fluctuate. If this is not controlled, then breakdowns of Bosch geysers may occur. When using for the first time, we recommend using the instructions for the Bosch geyser.

Another representative that is in demand on the Russian market is the Bosch 10 gas water heater. Such water heaters work with a hydrogenerator, they have many functions and automation. But here it should be noted that the cost of such speakers is an order of magnitude higher than their analogues. For example, Bosch flow-through gas water heaters of this series will cost you from 23,000 rubles and more. This series includes expensive devices with a closed combustion chamber. The operating principle here is completely different.

Such a geyser requires a pipe that sucks in air from the outside. Also, with the help of an air duct that comes out of the gas equipment, combustion products exit into the street. Advice, use and apply such equipment where gas pressure exceeds 0.3 or 0.5 Bar. The price of such a unit will cost from 40,000 rubles.

2.2 Advantages and disadvantages of Bosch geysers

Like every unit that runs on gas, it has its own disadvantages and advantages. Basically, these geysers are distinguished by high quality assembly and, most importantly, a good security system.

Here are some benefits:

Many options and types of Bosch units, which allows you to choose the right model for your home, office or production premises where people work.
The highest safety system, as well as strict control over the removal of combustion products from the outside.

Bosch gas instantaneous water heaters are used to prepare hot water in gasified facilities - these include private households, apartments in apartment buildings, commercial premises. Speakers from Bosch are characterized by:

Long service life;
Corrosion resistant;
High performance;
Fully automatic operation;
High efficiency indicator.

Bosch geysers are durable, because they are built on the basis of reliable heat exchangers and steel burners. The manufacturer paid attention to every detail, guaranteeing high quality equipment. The equipment of the dispensers resists corrosion and scale formation, ensuring high performance in any conditions - the most powerful models prepare up to 15 liters of hot water per minute.

Speakers from Bosch are fully automatic. They independently maintain the temperature of hot water, focusing on the strength of the flow - a system of electronic flame modulation works here. They differ from their analogues in their high temperature stability, which ensures user comfort. The speakers remain operational at low water pressure in the water supply and gas in the main line. Sensors for the presence of flame and the presence of draft are responsible for safety.

Bosch geysers are available in models with open and closed combustion chambers. The latter are characterized by the forced removal of combustion products. They also differ in the type of ignition - models with gas igniters, electric ignition and a hydrogenerator are on sale. Columns with gas igniters are equipped with piezo ignition; they are characterized by increased gas consumption. Electric ignition is powered by mains or batteries. As for models with hydrogenerators, they operate without third-party sources of electricity - microgenerators driven by water flow are used here.

By choosing Bosch geysers, consumers have at their disposal reliable and efficient instantaneous water heaters with a high efficiency rate. They consume gas fuel economically, are easy to operate, and do not create problems in operation. The user just has to set the required temperature - the column will do the rest itself.

You can buy Bosch geysers in the Teplodvor online store. Consumers have a choice of several model lines with a capacity of up to 15 l/min. Models with electronic flame modulation are distinguished by the greatest convenience and comfort. Equipment delivery is carried out throughout Moscow and throughout Russia - all speakers are accompanied by an official factory warranty from the manufacturer.

Thanks to a wide range of functions and high quality The Bosch geyser is very popular all over the world. Using this unit, you can create an autonomous hot water supply in an apartment, private cottage or country house. There is a large abundance of models of this brand on the market, among which a simple buyer may get confused and buy a Bosch gas water heater that is not suitable for certain conditions. To avoid such a situation, you should study in detail the operating principle of water heaters, characteristics and types.

Rating of the best models of Bosch geysers

The company's official website provides a wide range of Bosch gas water heaters, so every consumer can choose an option for themselves in terms of cost and technical specifications. Each classification differs in the type of ignition, power and performance, but they are all made in two main shades:

white;
grey.

Modifications are made at the Portuguese plant, but you can purchase Bosch devices in Moscow, St. Petersburg and in any other city through official representatives. There is a separate series of geysers, which are assembled in China, in fact, it is the most budget option. Let's take a closer look at which versions of devices are supplied to the domestic market.

Bosch 2000-O THERM

This line is considered the cheapest because it has a relatively low productivity of up to 10 l/min. and involves operation in combination with one water intake point.

Water heaters have a battery-powered ignition system, a tubular-type heat exchanger made of copper material and a steel burner. The units contain a controller for the degree of draft and flame level. The devices were also equipped with a liquid temperature and gas flow sensor. This version includes a Bosch W 10 KB device with compact size parameters and an estimated cost of 8,000 rubles.

Bosch 4 000-O THERM

The most popular series of Bosch geysers, which is available with automatic ignition or piezo ignition. In the first case, water heaters operate on batteries and require regular replacement of the voltage source; the second option requires constant pressing of a key to start operation. There are 3 varieties available on the market, with different indicators power and productivity level - 10-15 l/min.

BOSCH WR 10-2 P23

The units contain a heat exchanger consisting of copper material, due to which the device’s service life is increased to 15 years. In addition to all modifications, they are equipped with smooth modulation of the burner fire, thanks to which the device is able to independently maintain the specified temperature even during pressure surges.

One of the most important advantages is the ability to operate at a water pressure in the plumbing system of 0.1 atm.

This classification includes the following models:

modifications of the machine with the prefix “B” - WR10 2B, 13 2B, 15 2B;
semi-automatic with the prefix “P”, indicating the presence of piezo ignition - gas water heater Bosch WR 102P, 13 2P, 15 2P.

Each option has an individual column ignition method. In the first case, ignition is carried out without user intervention when opening the water tap; in the second, you need to light the wick in the device by simply pressing the desired key.

Water heaters with piezo ignition are significantly cheaper than devices with electric ignition, but each option has its own disadvantages - the need to replace batteries, the inconvenience of turning on the column at more than an arm's length, etc.

Bosch 4 000-S THERM

The main distinguishing characteristic of devices in this series is the presence in the design of a fan that creates forced draft. The devices can operate without a chimney system, so no special maintenance is required. Such units are especially relevant for apartment owners who do not have the opportunity to install a chimney.

Therm 4000 S WTD 12 AM E23

Exhaust of combustion products and supply fresh air carried out through a coaxial chimney. This element must be installed horizontally through the wall directly to the street. It is sold as an additional option and, as a rule, is supplied separately from the gas water heater.

The units also have a digital display for determining error codes, setting the temperature mode and other programs. This device, thanks to the burner fire modulation device, can maintain the specified mode with an error of up to 1°C.

The line includes the following models:

WTD 12AM E-23;
15AM E-23;
18AM E-23.

From this it becomes clear that modifications are made in three versions in terms of power and heating intensity of 12-18 l/min. They have a drawback - the devices operate on a 220 V power supply, so the models are considered completely energy-dependent.

Bosch 6 000-O THERM

The Bosch 10 2G, WRD 13 2G, 15 2G devices are equipped with a hydrogen generator and automatic ignition of the burner, which is produced by a stream of water. When the tap is opened, the liquid circulates into the column, and the Hydro Power system automatically starts the device with a hydrodynamic generator. In this case, no batteries or piezoelectric element are required.

Therm 6000 O WRD 10 2G

As for the heating efficiency, it is 10-15 l/min, depending on the modification. The control panel is equipped with a liquid crystal screen, which displays all information about the operation of the device.

Geyser Bosch 6 000-S, 8 000-S THERM

These series are considered industrial because they are capable of producing 24 and 27 l/min. and work on 4 mixers. Geysers have electric ignition and a liquid crystal screen on the front of the panel.

THERM 8000 S WTD 27 AME

In the first case, the units are equipped with two fans, in the second - with a special condensation device and an electric drive.

Frequent problems

Every consumer should be aware of the problems that he may encounter when using a Bosch geyser. Regardless of which model it is W10 KB or WRD 13 2G, where it was purchased and at what price, the following situations may arise during use:

The water heater does not light up or the fire goes out a few seconds after starting. The pilot burner needs to be cleaned.
The wick goes out when water collection begins. You need to check the fuel pressure reducer. This must be done if the device operates on bottled fuel.
The liquid does not warm up enough or does not change the initial temperature at all. You need to examine whether the temperature regulator, which is located on the front of the control panel, is set correctly.
The pilot light goes out for no reason. The draft or water temperature controller is probably turned on. This will require the intervention of a Bosch geyser repair technician.
The pressure of water coming out of the column has decreased. The cause of the problem is contamination of the heat exchanger, tap, or water unit. It is necessary to identify the source and clean it.
A water heater with an automatic system does not start. The batteries may be discharged or damaged; they need to be replaced with new ones.
