Blue fuel is the cheapest type of energy carrier. If a gas main passes near the house, connecting to it provides inexpensive and efficient heating. It is only important to choose the right heater. A mistake can be very costly: hefty energy bills and uncomfortable house temperatures. To prevent this from happening, let’s figure out what criteria they pay attention to when choosing a heater and get acquainted with the rating of gas boilers for heating a private house.

How to choose a gas boiler for heating a private house

The right choice is determined by several criteria. And most of them are interconnected. We list the points that deserve special attention when choosing.

  • Thermal power. It is determined based on the tasks of the heating system. It is best to calculate the required power and choose a boiler, focusing on this indicator.
  • Place of installation. Some devices need an insulated furnace, others are allowed to be mounted on the wall of the kitchen or corridor.
  • Equipment layout. There are wall and floor models. The first are compact and lightweight, hung on the wall. Floor devices — massive and overall, are installed on a flat solid surface.
  • Number of working circuits. If it is alone, the device only heats the premises. There is equipment with two circuits. The first is used for heating, the second heats water for household needs.
  • Burner type. There may be two options. Open varieties are less effective. They burn out oxygen and require connection to a full-fledged natural draft chimney. Closed burners use forced air supply, hot gases are removed through a coaxial chimney.
  • heating type. There are two types of gas boilers. Convection boilers burn fuel, the smoke is sent to the chimney. Their efficiency is in the range of 90%. This is the traditional type of heaters. Otherwise, condensation devices work. They use the heat from the combustion of the coolant and that which is obtained by the condensation of cooling water vapor. As a result, their efficiency can exceed 100%
  • The energy dependence of the heating device. Especially important if there are frequent power outages. In such cases, the house is left without heating.
  • Additional functionality. To ensure the safety and ease of operation of the equipment, additional systems can be built into it. This always increases the price of the boiler.

It is worth paying attention to the manufacturer. It is better to choose products of well-established brands and buy them in specialized stores. Buying equipment from an obscure manufacturer will cost less, but in operation, most likely, it will greatly disappoint.

All gas equipment is produced in strict accordance with high safety standards, because blue fuel is potentially dangerous. This applies to both expensive and budget models. But the former usually have multi-stage self-diagnostic systems and the most efficient automation. This must be taken into account.
