Advantages of floor-standing gas boilers

Gas boilers are a universal solution for heating homes, warehouses, and offices. They can be wall-mounted or floor-mounted. About 60% of gas equipment is floor-standing boilers. Their structure is so good that it has not changed significantly for decades.

Gas boilers are energy-dependent equipment characterized by low hydraulic resistance. Models can also be non-volatile. Floor-standing models are equipped with fire-resistant burners.

Key advantages of floor equipment:

High efficiency. With proper selection, installation and use of a gas boiler, the average efficiency value reaches 90%, regardless of the street temperature, type of equipment and type of fuel. Such devices are suitable for heating houses with a large area.

The operation of the boiler involves the release of minimal concentrations of harmful components into the air. This means that using floor-standing models at home is not hazardous to health (if the boiler works and is used correctly).

Models that are made from high-quality materials can have a long service life if used correctly. On average, a boiler can last 20-25 years.

Auxiliary control devices can be connected to maintain acceptable pressure and temperature parameters.

Ease of use. The control panel has some buttons - on/off, temperature regulator, fuel supply valve.

Natural gas has a low price, so financial costs are significantly lower compared to using electric models.

Safe use, which is guaranteed by several fuses and a self-diagnosis system.

Floor-standing gas equipment works excellently in places with unstable electricity. If the system does not have a circulation pump, certain models can operate in natural circulation mode.
