If we talk about how to choose a wall-mounted boiler, you should first decide which type you are interested in: single-circuit or double-circuit. After that, you need to determine the appropriate power of the device. This is done easily, for one square meter of room area with a standard ceiling height, 100 watts are needed. At the same time, an important condition is that housing does not coexist with unheated premises. If you want to heat a corner room with two windows, then 150 watts of power should be calculated per square meter. If you have any doubts about the correctness of the calculations that you made yourself, you can use the help of professional consultants working at the point of sale.
If you want to purchase a wall-mounted boiler and have already tentatively decided on the required power, then you can consider other issues. Another important point is related to the performance in terms of hot water supply. Everything is quite simple here. Tap water flows at a rate of 400 liters per hour. The characteristics of the boiler assume a minute capacity. With one pickup pointhot water is enough for an indicator of 6.6 liters per minute. When using two water points, the appliance must produce hot water at a rate of 13.2 liters per minute or more.
If you are considering a wall-mounted boiler, and everything is clear with the amount of water at the outlet, then you should decide on the temperature. Since we wash our hands and dishes, take a shower not in boiling water, but in warm water, there is no point in buying a device that will heat it up a lot. Comfortable for most is a temperature of 40 degrees. Each wall-mounted boiler in its characteristics contains information about the temperature range of hot water supply, for example, 35-60 degrees Celsius, as well as the parameter dt: 25 or 30. This number indicates the difference between the cold water entering the device and the hot water received at the outlet.
Above, a double-circuit wall-mounted boiler was described. If we talk about the single-circuit version, it should be noted that it is focused exclusively on heating tasks. It cannot be used to provide a house or apartment with hot water, so it is not so common among consumers. Gas wall-mounted double-circuit boilers are much more in demand. They are quite convenient, as they are very easy to mount on the wall, while they do not need much space. Their main advantage is the ability not only to heat the room, but also to provide hot water. Since these solutions are very versatile, they are often chosen for installation incountry houses.
At the moment, Ferroli boilers are the most popular among consumers, which has become a leader not only in Russia, but also in the world in the production of heating equipment. The characteristics of the products of this brand include reliability, high quality, wide control and customization options. At the same time, the cost of products of this manufacturer is often even lower than that of European counterparts.
