Central Heating System

A Central heating system consists of a boiler which heats the water, this is then pumped to the radiators or convector heaters where the heat is released into the rooms. The water then returns back to the boiler for re-heating.

Some central heating systems also circulate hot water through a coil in the hot water cylinder which in turn heats the domestic hot water which comes from our taps.

Central heating systems

The boiler is the main component of a central heating system and can come in many forms, they can use gas, oil or solid fuel. The most common is gas due to the availability and ease of use. In rural areas where there is no mains gas, bottled gas can be used.

Oil fired boilers again are mainly used in rural areas where there is no mains gas, but an oil storage tank and access for tankers is necessary.

Solid fuel boilers are the least popular mainly due to the dirt and inconvenience of solid fuel, also a separate heater such as an immersion is necessary for summer when the solid fuel heater will not be being used.
