At the moment, the market presents a fairly large assortment of boilers /, which in the technical language are called water heaters of accumulative electric. They are a tank with a heating element inside, where water heats up and a given temperature is maintained.
In addition to electrical, there are also gas boilers. Let’s try to figure out what type of water heating and when it turns out to be more preferable. The biggest advantage of gas water heaters is that they are much more powerful than electric. If the average power of an electric water heater is in the range of 1.5-3 kW, then the power of a gas burner is most often at least 7 kW. If you transfer this during the time required to heat the water, it turns out that the volume of water, which the gas boiler will heat up in an hour, the electric one will need 3, and possibly 4 hours. However, gas boilers have their disadvantages. Firstly, at least it should be possible to connect to a gas network. To install a gas boiler, you need to make a chimney, in addition, the installation of the water heater itself is also quite difficult and may require significant investments. There is a risk of gas leakage and the probability of an explosion. Therefore, it is better to trust trusted manufacturers and choose not the cheapest models of water heaters – safety and reliability above all.
And although the use of gas when heating water is more profitable, electric water heaters are most popular, which is apparently associated with their lower cost and simplicity of installation.
When choosing an electric water heater, you should definitely pay attention to the thickness of its tank. After all, this is a kind of thermos, therefore it is natural that the thicker the walls, the longer it can maintain the temperature of the water, which is an important indicator. Of course, each of us wants the water heater to occupy a smaller place, but it is better to choose a quality device than to suffer with an extra energy consumption or constant repairs. In addition, people seeking to leave more free space in and so small apartment should pay attention to horizontal models of water heaters, the cost of which is more than standard devices.
