What is Central Heating?

Central heating is a method of whole-home heating in which warm water circulates through a closed network of pipes, carrying heat around the home. These pipes can lead to radiators or they can be laid in the floor for underfloor heating. It is not uncommon to have a combination of both radiators and underfloor heating.

Central heating systems have four major components:

2. Distribution

All underfloor heating systems use a manifold.  The manifold provides flow and return circulation of warm water at the correct temperature and flow rate to ensure an even, comfortable floor temperature throughout your home. 

The manifold is best positioned centrally within your home. This keeps underfloor pipe circuit lengths to a minimum, helping to balance the system and control the temperatures within the rooms.

The manifold, which is contained in its own cabinet, is ideally situated within an airing cupboard, utility or cloak room. They should be accessible for maintenance and servicing.

4. Controls

Most systems have a wall-mounted thermostat. A thermostat monitors the room temperature and switches the heat source off when it’s warm enough, then turns it back on again if the room temperature drops.

Other central heating controls include timers that turn the boiler on or off at set times, programmers that allow you to adjust temperatures for different days of the week.  Another popular option is a smart thermostat. These work remotely via your mobile or computer, so you can adjust the temperature in your home even when you’re not there.
