Condensing combination boilers
We install A-rated gas boilers, which provide a combination of central heating and hot water. This is a very efficient option for most homes.
For larger homes that need more hot water, we may supplement this with a FlowSmart system, which improves boiler performance and avoids the need for storing hot water in tanks.
The GasSaver unit extracts heat from the waste gases that are expelled through the flue. This is then used to pre-heat the cold mains water before it enters the boiler. This means the boiler uses less gas to produce heat and hot water – saving on energy bills and reducing emissions.
The thermal store, in larger homes using the GasSaver unit, further pre-heats and stores water, so the boiler works less to produce consistently hot water for a longer period.
Heat is lost through the floor, walls and roof, and particularly doors and windows. Without careful design, thermal bridging lets heat escape easily, and wastes energy in heat generation.
Modern A-rated double-glazing is used, generally with solar/thermal glass, gas-filled cavities and warm-edge insulated spacer bars. This reduces heat loss and maximises solar gain. The frames are compartmented to reduce heat loss, and weather-seals provide full protection from the elements.
