What are gas heating boilers?

Keep in mind! A gas boiler is a device that is the central element of liquid heating.

It is used for heat supply of buildings, separate premises, private houses and apartments. The popularity of the units is due to the low price of gas used as fuel, autonomy, and safety.

gas boilers easy to use, environmentally friendly, wear-resistant.

What characteristics to look for when choosing a device?

When buying a gas boiler special attention should be paid to these parameters:

Power.
It is determined in accordance with the quadrature of the room and climatic conditions.
Mounting type.
Units are floor and wall.
The first ones are more bulky, have high power, and are necessary for heating large rooms. The second are compact, budget-priced.
The number of contours.
Single-circuit ones perform the function of only a heating device, double-circuit ones provide hot water.
Safety.
A useful feature is that the device automatically turns off in case of breakdowns, emergencies.

The best brands of gas boilers

Note! The following manufacturers of gas equipment are in particular demand among consumers:

Bosch.

Features of choosing a floor boiler for a private house

Note! When choosing a floor-standing boiler in a private house, the key characteristics are:

Power.
You need to pay attention to the minimum power of the device. The smaller it is, the more economically the boiler works.
The number of contours.
If the house requires hot water, it is worth stopping at two-circuit models.
When the issue with hot water was resolved earlier, a single-circuit boiler is sufficient.
Burner type.
There are single-stage (operate at the same power level), two-stage (two power levels are provided), modulating (automatic adjustment of the flame strength, varies depending on the temperature in the room).
Modulation models are considered the most economical to maintain.
