HOT & COLD WATER SYSTEMS
To heat a property with a boiler, water is heated and then distributed to rooms pipe work. Heat is introduced into the rooms via convection radiators.

A boiler with a cold water header and hot water storage tanks can be used to heat a house.
Alternatively, a combination (“combi”) boiler may be used. Combi boilers are suitable for small dwellings, and simultaneously supply hot water for heating and sinks / taps.

Under-floor heating can also be used to heat a building. Hot water is pumped through pipes which are set into the floor screed. As heat rises, it warms the floor slab and the air in the room.
