Central Heating Systems | Central Heating Installation Services

Central heating  uses water or air  to distribute heat to various areas  of  your home.

Central heating is more efficient than individual room heaters and it also offers a lot more comfort, as heat is distributed more evenly around your home.

According to Wikipedia, the invention of central heating is often credited to the ancient Romans, who installed systems of air ducts called hypocausts in the walls and floors of public baths and private villas.

New heating systems with 1, 2 or 3 zones independently controlled.

Central heating system components

Central heating system that relies on water for heat distribution, usually comprises of :

  • a central boiler
  • a central heating pump (water pump)
  • radiators
  • a series of pipes connecting radiators to a central boiler
  • heating controls

The boiler heats the water and (normally) a pump circulates the water through the pipework and radiators and back to the boiler.

Central Boiler

The heart of the central heating system,  is  a central boiler or a heater. Various boiler types are explained on a separate page.   Selecting your boiler type is probably the most important decision you need to make before installing your central heating.
Radiators can be pretty - RadArt radiatorsYou need to consider not only the costs and environmental factors,  but also available space, heat efficiency, fuel storage area, available roof space, house location and position on stand, yard area and access, amount of water that needs to be heated and the availability/cost of the chosen source of energy in the future.

Watertech can advise you which type of boiler would be most suitable for your particular application. We also install several different types of boilers, so you can always ask us for a comparative quotation.


The radiators may be mounted on walls or buried in the floor to give under-floor heat.

Air-based heating systems use air vents and air ducts in place of radiators and pipes.

Radiators don’t have to be ugly, have a look at the example of a feature radiator from RadArt.


Modern water pipes are made of plastic, iron, steel or copper. For many centuries, lead was the favoured material for water pipes, hence the word “plumbing” derived from a Latin word plumbum meaning lead.

There are 3 basic arrangements for the pipework connecting the boiler to the radiators:

  • Single pipe loop
  • Feed and return pipes
  • Micro bore

The type of arrangement used in your heating system depends on the type of flooring, desired placement of the radiators, distance from the central boiler and many other factors.

Central Heating Pump

Water pump - an exampleA Central Heating Pump (also referred to as a Domestic Water Pump or Circulator Water Pump) circulates water in central heating systems from the boiler to the radiators and back.

Central Heating Pumps are powered by electricity and they work in conjunction with the boiler, zone valves and thermostats to provide heat for your home.

There are several pumps available on the market. We can advise you which pump would be the best for your specific application.

Heating Zone Controls
