If your main gas pipeline is connected to your site, then the issue of gas heating is solved very easily. Moreover, with the help of a double-circuit boiler it is possible to simultaneously heat the house and heat water for domestic needs. That's why this equipment is in great demand: more than 50% of the heating boilers available on the market are gas.
They are different - floor and wall, autonomous and volatile, equipped with a chimney or without it. Our today's article will tell you about wall-mounted double-circuit gas boilers for home heating.
How to choose a wall-mounted double-circuit gas boiler?
Wall-mounted boilers are recommended for installation in homes ranging from 100 to 350 square meters. m. They are simple to install, have a modern design and do not spoil the interior of your house. Typically, the wall boiler looks like a small hanging cabinet, inside of which all the necessary equipment is already installed. Compact dimensions are the main advantage of the wall-mounted boiler.
Among the main shortcomings we note the following:
- relatively weak water heating circuit, not designed for large volumes;
- small cross-sectional sections of the openings of heat exchangers - this often causes the formation of scale and boiler failure.
Wall-mounted boilers come with a boiler and a flow-through heater. The first option is more expensive, besides the capacity of the boiler is more than 100 liters, it is planned to be installed in a separate room - a boiler room.
Before you go to the store to buy, you must first make a calculation of the power you need a boiler. The ratio is approximately as follows: 1 kW of energy for every 10 sq. Km. m area, provided that the height of the ceiling does not exceed 3 m. Thus, by dividing the total area of the house by 10 and multiplying the resulting number by a safety factor of 1.2, we get the power of the boiler plant.
Another important point in choosing a wall-mounted double-circuit gas boiler is the number of hot water samples. In practice this means that the best place to install the boiler is the kitchen or the bathroom next to it. If this is a big house with several bathrooms located in different places (on different floors), then when you open a hot water tap you will have to wait a certain time until the water reaches the distance from the boiler to the mixer, which implies an additional water flow. In this case, it is better to install the boiler with the boiler, and not with a flow heater.
Today, many purchase turbo gas wall-mounted double-circuit boilers. Their distinctive feature is the closed combustion chamber of gas. Such equipment is usually installed in small rooms where it is not possible to equip a standard chimney. The wall-mounted gas dual-circuit turbine boiler has a high efficiency and comparatively high water heating capacity. However, its cost is high, and repairs are also costly.
Manufacturers have taken care of the safety of using a wall-mounted gas boiler. The design of most models includes the presence of flame sensors, traction control, and a thermostat that turns off the boiler when the water temperature rises excessively. If suddenly, for some reason, the gas supply stops, the operation of the boiler will be suspended without any dangerous consequences for you. Among the manufacturers of gas wall-mounted double-circuit boilers, the most popular companies are Navien (Korea), Baxi (Italy), Protherm (Slovakia), Valliant and Wolf (Germany).
