The criteria for choosing the Best Gas Boilers for Home Heating

The type of boiler

  • The low-temperature gas boiler: gives off a heat of around 40 ° C. There are two techniques, the fireplace mode, and the suction cup mode.
  • The chimney-type gas boiler expels fumes through a chimney. it uses the air in the room it is in.
  • The flue gas boiler operates without a chimney. It is waterproof and has two different circuits for air and fumes. The air it uses comes from outside.
  • The gas condensing boiler: produces temperatures around 90 ° C. It condenses the fumes produced during heating to exploit the heat produced by heating the water.

Floor or wall installation?

The floor installation is designed for reasonably large boiler models. It, therefore, requires fairly spacious premises. This technique is generally used to meet the high demand for heating. The wall-mounted boiler, on the other hand, is reserved for smaller rooms. It corresponds to more modest heating needs. It is usually done for dwellings without a particular location, basement, or annex. There are models designed to be accommodated in tiny spaces. It is also possible to separate specific boiler model elements to distribute them in two rooms.


The heat production required for a boiler will be calculated according to the room’s volume to be heated. The power required will be expressed in watts (W) or kilowatts (kW). Insulation can vary the calculation of heating requirements. The energy loss and the ITE Outdoor Temperature Index also play their role in calculating the boiler’s power.


It is expressed as a percentage. It is the relationship between the production and consumption of energy. The higher the percentage, the more economical the boiler. It varies according to the techniques used for the different types of gas boilers.

For low-temperature gas boilers, the efficiency is 90%. They cause little expense to purchase. In use, the savings made compared to conventional boilers are around 20%.

For condensing boilers, the efficiency is more significant than 105%. Their price is higher than other boilers, but their gas consumption is the most advantageous. It results in 30% savings compared to conventional boilers and 10% compared to low-temperature gas boilers.

Evacuation of smoke

Heating with a gas boiler causes the emission of fumes. This phenomenon can cause various inconveniences. There are specific rules to follow regarding your safety. When using a low-temperature gas fireplace with a chimney, it is essential to ensure the air’s constant renewal in the heated room. The room should, therefore, preferably be open.

How Gas Boilers Work

The boiler will consume the gas from a tank or a gas network. The combustion of the gas causes the heating body of the boiler to rise. The heat is then transmitted to the heat transfer fluid, usually water. The boiler thus supplies the various radiators in the home and can produce domestic hot water.


The gas boiler is installed quickly. You must be connected to town gas if you opt for natural gas. For propane gas, a storage tank is required.
