Which geyser is better
Vaillant is a German brand. These columns differ in quality, reliability and unpretentiousness in work. The columns of this manufacturer firmly occupy their niche in the market of water heaters, both gas and electric.
Electrolux - work almost silently, due to the small number of nozzles in the burner. Equipped with good reliability systems, equipped with all available safety sensors.
It is advisable to buy a gas water heater in specialized stores, where you are required to provide a certificate. Recently, cases of fakes have become more frequent, and in order not to become a victim of low-quality goods, avoid shopping in the markets or on the Internet without checking the license to sell this product.
For safety reasons, the geyser should only be installed by specialists. After all, proper installation is the key to safe use of the unit. Self-installation can lead to undesirable consequences.
Which gas column is better to choose
Power
This parameter determines how quickly the water will heat up. The more power, the faster the water heats up. Modern geysers have a power of 17 to 30 kW. A small power is enough to provide water heating in one place - a bathroom or kitchen. Columns with more power will allow you to use hot water at the same time in the kitchen and in the bathroom. To determine the power of your future column, you also need to take into account the pressure of the water. If it is small, then there is no point in buying a unit with high power.
Ignition type
Unlike the old two-lever columns, progress has stepped far forward and manual ignition is almost nowhere to be found. If you remember, the first speakers were kindled with matches. Now your attention is represented by two types of ignition - automatic and semi-automatic.
Automatic - the operation of the column starts automatically when the water is turned on. In this case, the spark is knocked out using a conventional battery or a hydrodynamic generator.
Semi-automatic (aka piezo ignition) - to ignite the flame in the column, you need to press a special button, and you can also set the required temperature on the panel.
The choice of ignition type depends on several conditions - whether there will be a socket next to the gas water heater. Or you are more comfortable using conventional batteries, changing them several times a year.
Burner type
The most popular type of burner, which is present in conventional budget gas water heaters, is constant power burners. The water temperature in such columns is set manually. The water pressure can change and the previously set comfortable temperature can either decrease or heat up. Agree, being in the shower, it is not very convenient. More modern speakers have a variable power burner. The column automatically adjusts to the previously selected temperature regime when the water flow changes.
Safety
For many consumers, it is very important to know which gas water heater is the most reliable. Gas column is a constant source of danger
Since gas or water supply failures often occur, modern columns are equipped with various sensors:
- Ionization sensor - when the wick is attenuated, it shuts off the gas supply;
- Overheating sensor - does not allow heating of water above a certain temperature;
- Flow sensor - when the tap is opened, the column turns on, when it is closed, it turns off;
- Combustion sensor - if the ionization sensor does not work, when the wick fades, the column will turn off by itself and cut off the gas supply;
- Temperature sensor - adjusts the power of the flame;
- Draft sensor - in the absence of draft in the chimney, the column does not turn on;
- Low water pressure sensor - if the water pressure is low, the column will not turn on.
Additional functions
The above characteristics will definitely help you decide which gas water heater to buy in an apartment, but there are some nuances that you can also pay attention to. Many speakers are equipped with a mini-screen that displays the water temperature
Thanks to him, you can set a comfortable temperature for you personally.
The presence of paintings or a special column design is not an important, but quite a pleasant nuance. Especially if you choose a column for the design of your kitchen. Speakers with non-standard colors and patterns will cost more than regular white or black heaters.
Regarding the waste products of combustion, columns can be chimney and turbocharged. If everything is clear with the chimney, a special pipe is led into the chimney, where the combustion products go.
As for the second one, it's a little more complicated. Such columns are placed in apartments that are not equipped with a chimney and ventilation. To remove exhaust gases, a hole is made in the wall, where a special tube is inserted. Smokeless equipment is expensive, but it is quite safe if installed correctly.
