Do you want your house to always have hot water and heating? Installing a gas water heater will ensure this for you. Independence from utilities, independent adjustment of the heating power - this is possible if the gas water heater for the apartment is correctly selected. What to look for when choosing? Is it true that the speaker is an explosive device? What criteria are important to consider? These and many other questions worry the buyer. Get ready to receive answers to each of them.
Features of choice
How to choose a water heater? The final decision is influenced by many factors. Start by parsing the column device. You need to know what the main components look like, from what materials they are made. Read more about this in the publication "How to choose a gas column."
Remember that the main part is the heat exchanger. It is better if it is made of copper. Then the efficiency of the device increases and the service life increases. When you open the faucet to produce hot water, with automatic ignition, heating starts immediately. If a model with piezo ignition is selected, you will have to light the device manually while holding the piezoelectric button.
pay attention to type of ignition. Automation is more expensive, but much more convenient in daily use.
When water is supplied, the system rises pressure, which opens the gas valve. Gas is supplied to the burner, a spark appears, a flame breaks out. The burner evenly heats the heat exchanger, through the tubes of which water moves.
Burner type. For uniform heating, select a burner with multiple grooves and flame modulation. The latter function will help save on fuel consumption.
Combustion products are discharged through a chimney or coaxial channel. It is important to understand in advance which type is suitable for your apartment: turbocharged or chimney.
Find out if the building has a common chimney shaft. In this case, it is allowed to install equipment with an open combustion chamber, when the smoke is removed naturally through the mine to the street.
In other cases, opt for closed-type speakers: there is a fan inside that forcibly removes smoke through a coaxial pipe.
To understand how much hot water the heater will provide, the power of the device will help. Its performance directly depends on this figure. A rating of 10–19 kW will provide one intake point. An average output of 20-24 kW is enough for a shower and faucet to work in the kitchen. The high power of the device 27–31 kW is suitable for three points and guarantees a stable water supply, without temperature differences.
Power is an important criterion. For an accurate determination, find out what is the pressure in the water system, gas line. If you install a productive technique at low pressure, it will not work properly.
To choose a safe technique will help the protection elements. Modern water heaters are equipped with sensors that detect violations in the operation of the device and block it until the problem is fixed.
- The flow sensor monitors the strength of the water flow that opens the fuel valve.
- The combustion (ionization) sensor detects the presence of a flame in the burner. In its absence, the heater turns off.
- A draft sensor in the chimney prevents carbon monoxide from entering the room.
- The heating sensor disables operation when the nominal temperature is exceeded.
- The safety valve releases excess water at elevated pressure.
How to choose the best equipment for quality and reliability? Comparison of the characteristics of different models in our review will help you.
Rating of geysers
Even good appliances have their pros and cons. Above, we examined the types of equipment, the principles of its operation. Now we turn to the detailed characteristics of geysers. In the top list, consider 5 models.
Neva 4510-M
The heater of the famous Neva brand has a low cost. Its functionality contains everything you need for convenient use. With a power of 17.9 kW, the model has a capacity of 10 l / min. Neva 4510-M is suitable for rooms where there are problems with pressure stability, the equipment can operate at 0.10 bar.
The combustion chamber is open, thanks to electric ignition, you do not need to connect the device to the network. Overheating protection, gas control are provided. Mechanical control with the help of regulators.
Cost - from 6000 rubles.
Bosch W 10 KB
Another budget model. Convenient control: opened the mixer - received a hot stream. This is possible thanks to battery electric ignition. A 17.4 kW device will heat 10 liters of water per minute. The copper heat exchanger is highly efficient.
The device also runs on liquefied gas in a cylinder. It has 12 nozzles for uniform heating of the radiator. It is connected to a chimney, combustion air is taken from the room. The following protective mechanisms are built into the heater of this model:
- traction control automatically turns off the product in case of problems;
- flame ionization;
- thermal sensor from overheating;
- safety valve.
It works well at low pressures of 0.15-12 bar.
Price - from 7000 rubles.
Ariston NEXT EVO SFT 11 NG EXP
The Italian gas water heater has a stylish design. The laconic control panel does not contain unnecessary elements. The operation of the device becomes convenient thanks to touch control. You get 11 liters of water per minute, with an average power consumption of 19.58 kW.
Closed combustion chamber with integrated fan. Carbon monoxide is forced off. Electric ignition from batteries saves on electricity consumption. There is a possibility of fixing the water level: the system will signal a cessation of heating.
Security Features:
- frost protection;
- self-diagnosis system;
- overheating prevention.
Connection to a gas cylinder is possible. Additionally, a chimney can be included in the package.
The cost is from 16,000 rubles.
Vailant MAG 14-0 / 0 RXZ H
Products of the Wilant brand will fit into your interior with dignity and will provide several water points. This powerful heater delivers 14 l / min, consuming 24.4 kW. The device is a closed type, so the products of combustion are discharged through a pipe. High-quality smoke can be removed by the built-in fan.
It is possible to adjust the temperature and 10 power levels. The burner made of chromium-nickel steel is equipped with a smooth modulation system from 40 to 100%. The copper radiator is coated with SUPRAL protection. The ignition is semi-automatic, holding the piezoelectric button is required.
The security system includes a draft sensor, the presence of a flame, gas control. Case size 350x680x259 mm.
Price - from 21 000 rubles.
Bosch WTD 27 AME
This unit combines ultimate power (47 kW), fast heating (27 l / min) and savings thanks to condensation technology. The latter provides for the collection of condensate in a separate container for future use.
The heat exchanger is made of copper, without additional impurities. The steel burner works great when using liquefied fuel. Included flame modulation function, turbocharged gas exhaust system.
For safe operation, the following are provided:
- flame control;
- temperature sensors;
- limitation of the heating temperature.
