Do you want your home to always have hot water and heating? Installing a gas water heater will provide you with this. Independence from utilities, self-adjustment of heating power – this is possible if the geyser for the apartment is correctly selected. What to look for when choosing? Is it true that the column 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 the right water heater? Many factors influence the final decision. Start by disassembling the speaker device. You need to know what the main components look like, what materials they are made of. Read more about this in the publication “How to choose a geyser”.
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 for hot water, automatic ignition starts heating immediately. If a model with piezo ignition is selected, you will have to ignite the device manually by holding the button of the piezo element.
pay attention to ignition type. Automation is more expensive, but much more convenient in daily use.
When water is supplied to the system, the pressure rises, which opens the gas valve. Gas is supplied to the burner, a spark appears, a flame flares up. The burner evenly heats the heat exchanger, through the tubes of which water moves.
Burner type. For even heating, choose a burner with multiple chutes and flame modulation. The latter feature will help save on fuel consumption.
Combustion products are discharged through a chimney or coaxial duct. It is important to understand in advance which type is suitable for your apartment: turbocharged or chimney.
Find out if the building has a shared chimney. In this case, it is allowed to install equipment with an open combustion chamber, when the smoke is removed naturally – through the shaft 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 performance of 20-24 kW is enough for a shower and a faucet in the kitchen. The high power of the device 27–31 kW is suitable for three points and guarantees a stable supply of water, without temperature changes.
Power is an important criterion. For an accurate determination, find out what is the pressure in the water system, gas line. If you install low pressure production equipment, it will not work properly.
Protective elements will help you choose a safe technique. 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 controls the amount of 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 is turned 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 in terms of quality and reliability? You will be helped by comparing the characteristics of various models in our review.
Rating of geysers
Even good devices have their pros and cons. Above, we examined the types of equipment, the principles of its operation. Now let’s move on to the detailed characteristics of geysers. In the Top list, consider 5 models.
Neva 4510-M
The heater of the well-known trademark “Neva” 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 atm.
The combustion chamber is open, thanks to electric ignition, it is not necessary to connect the device to the network. Overheating protection, gas control. Mechanical control, with the help of regulators.
The cost is from 6000 rubles.
Bosch W 10 KB
Another budget model. Convenient control: open the mixer – get a hot stream. This is possible thanks to the electric ignition on batteries. A device with a power of 17,4 kW will provide heating of 10 liters of water per minute. The copper heat exchanger has a high efficiency.
The device also runs on liquefied gas in a cylinder. It has 12 nozzles for uniform heating of the radiator. Connected to the 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;
- temperature sensor from overheating;
- safety valve.
Works well at low pressure 0,15-12 atm.
The price is from 7000 rubles.
Ariston NEXT EVO SFT 11 OF EXP
The Italian gas water heater has a stylish design. The laconic control panel does not contain unnecessary elements. 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 built-in fan. Carbon monoxide is forced out. Battery-operated electric ignition saves on electricity consumption. It is possible to fix the water level: the system will give a signal to stop heating.
Security elements:
- frost protection;
- self-diagnosis system;
- overheating prevention.
Connection to a gas cylinder is possible. In addition, a chimney can be included in the package.
The cost is from 16 rubles.
Vailant MAG 14-0/0 RXZ H
Vailant brand products will adequately fit into your interior and provide several water intake points. This efficient heater delivers 14 l/min, consuming 24,4 kW. The device is of a closed type, so the combustion products are discharged through the pipe. The built-in fan allows high-quality removal of smoke.
There is a possibility of regulation of temperature and 10 steps of power. The burner made of chromium-nickel steel is equipped with a smooth modulation system from 40 to 100%. The copper radiator is covered with SUPRAL protection. The ignition is semi-automatic, the piezoelectric element button must be held down.
The security system includes a draft sensor, flame presence, gas control. Case size 350x680x259 mm.
The price is from 21 rubles.
Bosch WTD 27 AME
This device combines extreme power (47 kW), fast heating (27 l/min) and savings thanks to condensing technology. The latter provides for the collection of condensate in a separate container for further use.
The heat exchanger is made of copper, without additional impurities. The steel burner works great when using liquefied fuel. Flame modulation function, turbocharged gas exhaust system included.
For safe operation are provided:
- flame control;
- thermal sensors;
- heating temperature limitation.
Error diagnosis is carried out automatically, highlighting the fault code on the display.
The cost is from 70 rubles.
We hope our article and review of models will help you decide which speaker to buy. Not only the characteristics and functions matter, but also how the appliances fit into the overall design of the room. Another tip: before going to the store, determine the optimal size of the water heater for your kitchen.
