A selection of the best geysers - ratings, comparisons, reviews
One of the main benefits in a house or apartment is the availability of hot water. The absence of a central warm water supply system forces the owner of the house or apartment to install a particular water heating system. If there is gas in the housing, then often the best choice for solving the problem of hot water supply is a gas column. In this case, it will be the most economical to use, in comparison with electric water heaters.
Any specialized company will be able to offer you a huge selection of geyser models of different capacities and prices. Not a specialist can easily get lost among them, not knowing all the subtleties and features of such equipment. So that you can unambiguously decide which model will be a successful acquisition for your home, we have compiled a rating of gas water heaters for reliability and quality. The rating is based primarily on the reviews and ratings of users of this equipment, as well as their main technical characteristics.

Which geyser is better flowing or storage
To begin with, we find out what kind of gas water heaters are generally on sale and talk about their main advantages and disadvantages.
First of all, experts divide them into two groups:
- Flowing;
- Cumulative.
The device and principle of operation of flowing gas water heaters (geysers)
The geyser has small dimensions, making it well suited for urban apartments. The gas column is connected directly to the cold water supply system. Such units can work both on natural and on liquefied gas. Passing through the heat exchanger, the water quickly heats up from the high temperature of the combusted gas and the already heated one is immediately fed to the mixer. Geysers are equipped with advanced safety systems ensuring reliable and safe operation.
Flowing gas column device:
1. Traction detector;
2. Overheat detector;
3. Gas-burner;
4. Gas flow regulator;
5. Hot water outlet
6. Exit for a chimney;
7. Manifold for combustion products;
8. Heat exchanger;
9. Gas pipe;
10. Water intake regulator;
11. Outlet for cold water.
The device and principle of operation of the storage gas heater
The main difference in the device and the principle of operation of the storage gas heater is that the heated water in it does not go into the water supply, but is stored in a special container. Water heating does not occur simultaneously, but gradually. The storage tank has good insulation, which contributes to a longer preservation of the temperature of the prepared water. As it runs out or cools, the water in the tank is automatically heated to the set temperature. Among the many models on the market, you can easily choose the one that will provide you with the right amount of water. You can find both a column for the kitchen, the tank of which is about 50 liters, and a bath device with a tank of 100 liters or more.
The device of the storage gas heater:
1. Gas check valve;
2. Gas adjustment knob;
3. Water temperature adjustment;
4. Gas-burner;
5. Ignition gas wick;
6. Thermocouple;
7. Nozzle of the main gas burner;
8. Inner protective coating;
9. Thermal insulation of water tanks;
10. External protective cover;
11. Damper;
12. Anode to prevent scale and corrosion;
13. Drain cock;
14. Cable from the traction detector;
15. Chimney base;
16. Divider;
17. Cold water supply pipe;
18. Water flow swirl to intensify mixing;
19. Emergency Relief Valve Socket;
20. Pipe leaving for hot water;
21. Traction stabilizer.
In which case it is advisable to install a flowing gas column
There is no place to install surround equipment. In contrast to the storage column, which includes a tank with a volume of tens, or even hundreds of liters, the flowing one is small in size, which allows you to install it with minimal space requirements.
Limited budget. Flowing gas water heaters are much cheaper than storage. The difference in cost can reach up to 3-6 times. It is this factor that contributes to the greater spread of flowing gas columns.
Reliability and durability. If we compare two heaters, then flowing will be more reliable, due to the fact that it uses fewer diverse systems and mechanisms.
In which case is it advisable to use a gas storage heater
The presence of a large number of water consumption points with a high probability of simultaneous use. If it is assumed that several people will use hot water at the same time, then in the case of using a flowing column, a decrease in water pressure and an increase in its temperature will be observed. Storage heaters are devoid of this drawback. In this case, the storage water heater will be your best choice.
Unstable gas pressure. Heating does not occur immediately, but gradually - depending on the model’s power and tank volume, this takes from several minutes to several hours. Therefore, there is no need to consume a large amount of gas in a short time, which means that there will be no sharp load on the gas pipeline. In the case of a flowing column, all gas pressure surges will affect the water temperature; in the case of a storage heater, this will only affect the rate of heating the water in the tank.
The need to heat water to higher temperatures. The water in the storage water heater is able to heat up to a higher temperature. All models have the function of adjusting the maximum temperature. The user can set the optimum heating level to reduce gas consumption and lower costs when paying for utility bills. High-quality thermal insulation ensures that even a few hours after heating, the water will maintain a high temperature.
Low pressure cold water. If a low water pressure is observed in a cold water supply system, then the operation of a flowing gas column will be difficult or even not possible. In turn, the storage water heater is able to operate at a fairly low pressure.
Weak smoke system. Flowing heaters are more powerful devices and require a larger diameter chimney (110 - 130 mm). Gas boilers are less powerful devices and do not form, at the same time, such an amount of exhaust gas that allows them to be used with a chimney diameter of 90 mm.
Low quality cold water. In hard water regions, scale formation may occur. Over time, the salt layer on the inner walls of the spiral heating element of the flowing gas column will increase, due to which the efficiency of the heater will decrease, as well as its heat transfer. In the case of storage gas heaters, this problem is less acute.
