Heating systems

Air source heat pump central heating

Installing an air source heat pump has the potential to reduce your homes heating costs by between 10% and 50% and carbon eissions by 75% compared with a gas boiler.

They work by extracting heat from the outside air and can by over 300% efficient compared with 80% for gas boilers.

An external box unit is installed outside your home and connected to a hot water cylinder inside your home which feeds your central heating and hot water pipework.  For the system to work efficiently your radiators may need to be replaced with larger ones which can keep your home warm with the lower operating temperature achieved with a heat pump system.

Heat pump central heating systems work best in homes with reasonably well insulated homes such as those with good loft insulation, double glazing and insulated cavity walls.  However they can also be instlled in older solid walled homes dependent on the circumstances which can be assessed by an MCS accredited installer.  Installation costs are often covered over time by the government's Renewable Heat Incentive payments or upfront with a Green Homes Grant or Council Green Affordable Warmth Grant.  Cost range between £7,500 for a 2 bed home to £12,000 for a large 4 bed home.

Heating controls

Having good heating controls fitted will also help you heat your home more efficiently and lead to lower energy bills. Controls include programmers, room thermostats and thermostatic radiator valves: 

  • A programmer lets you control when the heating and hot water comes on and goes off.

  • A room thermostat turns the heating off when the room reaches the set temperature.

  • Thermostatic radiator valves control the temperature of individual radiators. 

Electric storage heaters

Modern electric storage heaters are better insulated, have better controls, and many of them have fans to help the distribution of heat. This means that less electricity is needed to keep the home warm.
