Recently, not only in private homes, but also in apartments, residents are increasingly installing gas boilers, which, as is known, allow you to set the preferred temperature regime and, accordingly, significantly save money. The modern market offers a lot of options for these devices, we also consider the advantages and disadvantages of gas single-circuit heating boilers.
What is a single-circuit gas boiler?
A single-circuit gas boiler is a special device that serves to heat water in the system, which, in turn, heats the rooms. It turns out that the main thing, what distinguishes a single-circuit gas boiler from a two-circuit one , is an exclusively heating function. While the latter, more versatile, also heats water for hot water supply at home.
By the way, there are different heating boilers. They are divided according to their technical features and the type of installation on the wall and floor. The first distinguishing feature is the compactness of the dimensions. As a rule, such an aggregate consists of the following elements:
- burners;
- expansion tank;
- heat exchanger;
- circulating pump;
- security and management systems.
The design of outdoor single-circuit gas boilers for home heating includes the following components:
- automatic protection and control system;
- a burner;
- a cylindrical heat exchanger;
- chamber for combustion of gas.
True, they are large in size, and are made of strong cast iron or steel, and, naturally, are more durable and durable. But for their installation requires a separate room, because such devices are quite sensitive to temperature fluctuations.
A number of modern models of single-circuit boilers include a closed combustion chamber with forced draft. Combustion products are discharged through a special coaxial tube. Such units are called turbine single-circuit gas boilers.
How to choose a single-circuit gas boiler?
The main criterion for choosing a single-circuit gas boiler is the area of the room, which should be heated. The matter is that proceeding from this, the capacity of the heating system is selected. Usually the calculation is based on the fact that for every eight to ten square meters, 1 kW of power is needed.
Next, choose the type of location for your future boiler. Compact wall-mounted boiler - choice for an apartment, villa or small house. It is able to heat up to 340 square meters. The power of such products reaches about 25-60 kW. For large rooms
A single-circuit boiler is an option for those who need only heating. However, if you decide to produce and heat water for domestic needs, give preference to a single-circuit gas boiler with a boiler . An indirect boiler is built into the heating system, which is connected as one more battery.
When buying a gas boiler, be sure to pay attention to the presence of such important options as:
- blocking of work in the absence of gas supply, smoke removal, power drop
- warranty service and the possibility of repair after its completion.
The most popular manufacturers of single-circuit boilers are Viesmann, Ariston, Termet, Viallant, Beretta and Viasmann.
