What is a heat pump?

A heat pump is a highly energy-efficient and eco-friendly alternative to traditional gas or oil boilers. It works by extracting renewable heat from the air (air source heat pump) or the ground (ground source heat pump) and converting it into usable heat for your home.

Heat pumps are ideal for well-insulated homes and can significantly lower both your carbon footprint and energy bills.

Key benefits of installing a heat pump

Highly efficient heating

Air source heat pumps can achieve efficiencies of up to 350%, meaning they produce 3.5 kilowatts of heat for every 1 kilowatt of electricity used - far outperforming traditional heating systems.

Lower energy bills

Heat pumps are especially cost-effective for homes currently using oil, LPG, or electric heating. Greater savings can be achieved by combining heat pumps with solar panels, using clean energy to power your heating system.

Government grants available

The UK Government’s Boiler Upgrade Scheme (BUS) offers grants to support the cost of installing a low-carbon heating system like a heat pump.

FAQs

  • Very similar to a normal boiler. It is advisable to have an annual service in order to keep the warranty valid and ensure that the unit is working as efficiently as possible.

  • No. Modern heat pumps are often quieter than boilers and many other appliances we use in our everyday life.

  • Not much. The model and size of the heat pump depends on the heat requirement for the property so varies slightly. Most heat pumps are roughly 1m wide x 1m tall and sit against an external wall. Inside, the new heat pump cylinder will typically go in place of the existing cylinder.

  • Yes. Air source heat pumps have the capability to remain efficient even in extreme cold; they continue to function down to -20°C.

  • After carrying out a survey and completing heat loss calculations, a report is compiled explaining the size of the system and estimated running costs. A typical installation takes around 3-4 days.
