How Does Central Heating Work?

Central heating is the process of heating the entire building by use of central heating appliances. Central heating is also known as ‘demand-side’ systems, because the central system is designed to keep your home at a certain temperature, based on how much demand you put on it. For instance, when you turn on the boiler in your home, it’s using the energy it has to heat up the water in the rest of the house, and that energy is mostly supplied from gas.

Central heating systems take an initial input (in the form of fuel) and produce a final output (usually heat), which can be either hot or cold. All central units are designed to be extremely versatile, so that they can supply all the power, space, and need for heat in your home. Plumbing systems including central heating often need servicing. For a range of Copper Pipe products, visit

Central heating systems typically have a single main heating appliance, usually a gas boiler. There are two main parts: burners which deliver and distribute heat, and heat exchangers which condition and convert the heat that is supplied by the burners to heat the water in your radiators. There are different types of central heating systems including: Fuel powered heat pumps; Water-powered heat pumps; Electrical heaters; and Natural Gas/oil furnaces.
