Are you looking to generate your own heat and save money on your energy bills? Then Heat Pumps may be the answer for you!

There are two types of Heat Pumps and these are:

  • Air Source Heat Pump
  • Ground Source Heat Pump

How do Air Source Heat Pumps Work?

Air source heat pumps absorb heat from the ambient air outside and use it to heat your home. They work even when the temperature is as low as -25°C.

Air source heat pumps use a fan to absorb heat from the outside air at low temperature into a fluid. A heat pump compressor then increases the temperature of the fluid and transfers the higher temperature into the heating system of the house. Once the heat has been used, the cooler fluid circulates back to the unit outside to start the cycle again.

Unlike a standard boiler system heat pumps work at a lower temperature making them more suitable for underfloor heating systems.

To get the most out of your ASHP you need to make sure your home is well insulated to ensure the heat generated doesn’t easily escape. 

How do Ground Source Heat Pumps Work?

Ground Source Heat Pumps take heat from underground using ground loops. The heat generated from the GSHP is then used to heat radiators, underfloor heating and hot water in your home.

Water and antifreeze flow through the ground loops and pass through a compressor. This raises it to a higher temperature providing you with the heating and hot water for your home.

The heat pump can be used throughout the year as the ground stays at the same temperature.

Heat pumps have several benefits over traditional heating systems, these are;

  • Lowering your fuel bills, a typical saving is 30% over a gas system and 50% over LPG and oil.
  • Lowering your CO2 emissions making your home more environmentally friendly.
  • No fuel deliveries are required.
  • Air source heat pumps are cheaper and easier to install than ground source heat pumps.
  • Air source heat pumps require very little maintenance, they are referred to as a ‘fit and forget’ system.
  • RHI payments from the government of 10.85 pence per kWh for an air source heat pump or 21.16 pence per kWh for a ground source heat pump for 7 years (domestic tariff)
