The technology inside an air source heat pump is very similar to that of a domestic fridge – transferring heat from one place to another – the back of your fridge is warm because it is removing heat from the food inside the fridge out into the room.
An air source heat pump sits outside your home and extracts warmth from the outdoor air. It upgrades this renewable heat energy and transfers it inside the home to provide hot water and heating for radiators and/or underfloor heating. The self contained unit only requires electric and water connections.
Like your fridge, it will do this quietly and reliably, all year round, even in sub-zero temperatures down to -20ºC. In addition to low running costs, the pump is classified as a renewable energy source because it captures free energy from the air.
For every 1kW of electrical input power, the pump harvests and upgrades renewable heat energy from the outdoor air to provide the home with an average of at least 3kW of heat output*. This ‘free’ 2kW of renewable energy is then eligible for seven years of payments from the RHI. With an average 3-bed family home in the UK needing around 15,000kWh of heating per year, you can quickly see how the RHI payments can really make a difference.
You can increase these quarterly payments even further by adding a Metering & Monitoring Service Package (MMSP). This makes you eligible for an additional £805 payment in the first year, and an extra £134 for each subsequent year of RHI payments.
