How does a boiler work and general principle of
a boiler
A boiler is also more commonly known as central heating. It feeds the radiants of the hearth and, also, produces, most
often, the domestic hot water. Regardless of the fuel chosen, the Boiler installation in Harrow is roughly similar.
The general principle of a boiler
A boiler transmits heat, calories, water or heat transfer fluid depending on the model, which will, in turn, be transmitted
to heat emitters (radiators, heated floors ...) and water for heating. the production of domestic hot water. In some
cases, the Boiler installation in HA1produce only heat, but no domestic hot water. To produce this heat, the boiler
produces a combustion, realized thanks to a fuel ( gas , fuel oil , wood , or pellets). Water or coolant circulates in the
boiler, around and in the firebox. The temperature of this liquid rises as it winds closer and closer to the fireplace, and
then once at the right temperature, the liquid continues its course towards the heat emitters. It is also used to heat
water for sanitary purposes, either instantaneously or by accumulating in a balloon.
Variations according to boiler systems
The basic operation remains the same for all boilers. It is somewhat different depending on the types of boilers. Thus,
for a condensing boiler, the performance is increased, thanks to the additional use of combustion fumes usually lost
during the evacuation of combustion gases. These contain water. This steam condenses in the boiler, allowing increasing
the temperature of the coolant, in addition to conventional combustion, and thus improves the efficiency for a
reduction in energy consumption. When we talk about boiler at low temperature, the principle remains the same,
except that the temperature reached is lower. A sucker Boiler installation in HA2 takes air not in the room where it is
located, but directly outside. The boiler itself is therefore hermetic and is not connected to a conventional flue, but to a
double concentric duct, coming out on the facade. The air is thus taken from the outside of the duct and the smoke from
the inside.
The operation of the condensing gas boiler
The operation of the condensing gas boiler is based on the same principle as a traditional boiler and also makes it
possible to take advantage of all the energy produced during the combustion of the gas. In a conventional boiler, the
central heating water circuit is warmed by burning natural gas. The Boiler installation in HA3 takes advantage of the
energy contained in the flue gases. The fumes emitted during the combustion of natural gas contain water vapor. The
latter condenses, releasing heat. The return water from the heating circuit heats up with this energy. The evacuation of
the water released during the condensation (the condensates) is done by the sewage network.
The condensing gas boiler can be used in many cases
Whether attached to the floor or wall, a condensing gas boiler can be connected to all hot water heating systems. For a
house with a basement or a garage, the boiler on the ground is indicated. The wall-mounted boiler is particularly
compact and has the advantage of freeing the floor surface. Being able to be equipped with a hot water tank, the
condensing gas boiler is generally supplied by the town gas network, but can also be supplied by means of a tank.
