Underfloor 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. The heat source warms the water circulated through the pipes that lead to radiators or to the pipes laid in the floor for underfloor heating. Underfloor heating can be installed into new homes and retrofitted into existing homes.
House can be heated via
- Underfloor pipes in concrete
- Radiators on the wall
- Ceiling/wall panels
- Water is generally heated by heat pumps or boilers
- Very efficient way of heating cooling the whole house
