An ordinary apartment, a country house or a small dacha - the choice of a gas water heater can be relevant for any residential property. This type of water heater is economical and convenient because it can quickly heat the required amount of water. Its dimensions are minimal, and in terms of energy consumption, speakers are usually more profitable when paying for utilities. It should also be noted that the best instantaneous gas water heaters are capable of providing high purity of hot water, which conventional pipelines cannot always boast of. You can connect one device to several points at once: bath and shower, kitchen sink.
Which brand of geyser is better?
- Bosch . A German giant that is familiar even to people who are poorly versed in consumer technology. The Bosch brand is represented in more than 150 countries around the world. The corporation from Germany owns hundreds of branches in different countries, as well as its own factories, including Russian factories.
- Neva . As you can guess from the name, this is a St. Petersburg enterprise. The manufacturer implements the latest technologies in its products, which allows it to keep up with foreign competitors. The design of their gas instantaneous water heaters is predominantly classic, but the range also includes stylish columns with designs.
- Electrolux . A famous Swedish brand that provides up to 3 years of warranty on gas water heaters of its own production. In addition to the highest quality, Electrolux equipment boasts variety and stylish design.
- Ariston . The company comes from Italy, which began operating in the 30s of the last century. This brand is a leader in the market of heating and water heating equipment. Like Bosch products, Ariston equipment is available to customers in over 150 countries. The range of the Italian company is extensive and constantly updated.

Heat exchanger
Water is heated while it flows through the heat exchanger. It is a metal pipe installed above the burner. The shape of the heat exchanger in a gas water heater is special - a pipe with fins is laid in a snake at the bottom, then a sheet of metal is installed around it, on top of which the pipe is wound in a spiral. Water flowing through this long path is heated by the heated metal.
This is what a heat exchanger for a gas water heater looks like
Heat exchangers are made from galvanized steel (the most budget option), stainless steel and copper. The best in terms of efficient heat transfer are copper. They are the most economical, but also expensive. The most durable ones are stainless steel, but they are much worse at heat transfer. Which gas water heater is better in this case is up to you to decide. Choose the quality that is more important to you.
If you decide to buy a gas water heater with a copper heat exchanger, do not try to find a cheap model. In order to reduce the price, manufacturers use low-quality copper, and the tubes are also made with thin walls. Such a heat exchanger will serve the warranty period, and then problems will begin - a leak will appear.
If you remove the casing, you will see fistulas in the tubes through which water drips. They are located mostly on the outside of the pipe, exactly in the place where condensation forms. If the pipe is of normal thickness, this is not a problem, but it quickly corrodes thin walls. Such a heat exchanger with a leak does not need to be replaced (it costs about 1/3 of the total price), it can be soldered. You will need refractory solder with a melting point of about 200°C, a powerful soldering iron and soldering flux. The technology of work is usual - clean the damaged area to bare metal, degrease, tin, and solder.
Criteria for choosing a geyser
- Productivity . If there are 1-2 people living in a house, then there is hardly any point in choosing a water heater with a rating higher than 8 l/min. For 2-3 people you will already need about 10 liters. A large family of 4-5 people, in turn, will benefit from models capable of providing a capacity of 13 l/min or higher. Also note that the water supply network must provide adequate pressure. If it can only produce 10 liters per minute, then there is no point in choosing a more efficient instantaneous water heater.
- Power . A value directly related to productivity. The minimum recommended by experts for apartment owners is 16-17 kW. But this is enough to simultaneously service only one water intake point. If one family member needs to take a shower and the other needs to wash the dishes, then it will be difficult to do this. For these tasks, a power of 20 kW is sufficient. For private homes and large families, over 26 kilowatts will be required.
- The combustion chamber . In inexpensive gas water heaters, opening the chamber is common. To operate, they draw air from the room in which they are installed. Air enters the column with a closed chamber from the street. They have improved safety, but increased noise levels (due to the presence of a fan).
- Removal of combustion products . The classic version uses a chimney. Such instantaneous water heaters are ideal for homes where it is already provided (or can be equipped additionally). Turbocharged models exhaust combustion products through a pipe in the wall. For this purpose, a fan is required in the design of the device.
- Heat exchanger material . Steel solutions are inexpensive, quite reliable, but not the most effective. If the heat exchanger is made of highly purified copper, then its heat transfer is higher, which provides a noticeable increase in efficiency.
- Safety system . Modern instantaneous water heaters use various protective mechanisms. For example, an overheat sensor turns off the column if its temperature has reached a peak value. An emergency relief valve protects the device from overpressure. Gas control shuts off the fuel supply when the flame goes out. The draft detector will not allow you to turn on the dispenser without draft in the chimney.
Device and principle of operation
An idea of how to choose a gas water heater for a private home can be given by knowledge of the structure, operating principle and its existing varieties. Based on the principle of operation, these devices are divided into two types:
- Flow-through.
- Cumulative.
The mechanism of operation of the first is to simultaneously supply water to the heat exchanger and turn on the burner. Next, the heated water immediately enters the mixer. The temperature is controlled by the flow rate in the water supply. The main feature of the flow-through version is the absence of a container and, as a result, minimal dimensions. Therefore, it is ideal for installation in cramped conditions - in a small kitchen, near equipment, etc.
Storage devices have a special heat-insulated tank. There is a burner underneath it. Switching on, switching off and the period of operation is controlled automatically, based on the indicators of temperature sensors. As soon as the water temperature in the tank drops below the set value, the heating module is activated, and if it is exceeded, it turns off.

Unlike the one discussed above, the devices of this version have a supply of hot water and are large in size. Therefore, they are suitable for spacious rooms. In addition, with their help you can obtain heated water for a long time even when not in use. This is especially true when there are several sources of its consumption in the house - kitchen, bath, sauna, bathrooms.
Helpful information! Flame initiation can be done manually or automatically. The first option involves pressing the piezoelectric element button every time you want to use the device. This is not very convenient for frequent use. Therefore, modern geysers, whose reliability and quality ratings are high, are equipped with automatic ignition systems. They are powered by batteries, mains or hydro generator.

Which gas water heater is better to buy?
For your convenience, we have collected above the basic tips for choosing instantaneous water heaters. Depending on the size of the house and the number of people living in it, buy speakers of appropriate performance. It’s difficult to definitely single out the best geysers, because each brand has its own trump cards. For example, Gorenje offers devices with excellent performance and low cost. Bosch is distinguished by legendary German reliability. Do you want to support a domestic manufacturer? Give preference to BaltGaz products or Neva geysers.
