Our Air Source Heat Pump

We have a fantastic partner company that can complete Air Source installations

What is an Air Source Heat Pump?

An Air Source Heat Pump is one of the most commonly used and simplest of heat pumps to install. It uses the outside air to heat your water to high temperatures, either for hot water use or space heating, through a radiator or underfloor heating system and can work at temperatures as low as -25°C.

With an Air Source Heat Pump 1kW of electricity will produce up to 4kW of heat energy in your home, reducing your carbon footprint and saving you money.

It is often quoted that you can save up to 50% on your annual heating and hot water bills whilst reducing your output of harmful carbon emissions by up to 6,100kgs per year, helping in the fight against the worrying effects of climate change.


How does it work?


By efficiently supplying hot water to the radiators at a constant temperature Air Source Heat Pump’s provide a controlled level of warmth year-round and all the hot water you need. An Air Source Heat Pump is based on one simple principle, heat transfer – using a small amount of energy to transfer low-grade heat from the air to high-grade heat, heating water to high temperatures. Essentially transferring heat from a ‘free heat source’ like the air to a ‘heat sink’ like your home.


The Vapour Compression Cycle


  1.  The outside air is pumped across refrigerant filled coils, causing the liquid refrigerant to increase in temperature and produce hot gas.
  2.  This hot refrigerant gas then enters the compressor where its temperature increases further as a result of the compression process – much like a bicycle pump heats up during its use.
  3.  The hot refrigerant gas is then condensed turning back into a liquid. This, now high-temperature water, is distributed via the buildings heating circuit to provide you with hot water and heat your home.
  4.  This process is repeated to provide a constant temperature to the property.
