Air Source Heat Pumps


Air Source Heat Pumps are becoming a popular choice for homeowners who are looking to install renewable energy solutions in their home, changing conventional boilers to a renewable energy source.

Renewable solutions such as our range of air source heat pumps are one of the most economical, and eco-friendly heating solutions on the market and help homeowners not only to reduce their carbon footprint, but to significantly reduce their heating bills.

Sunlite Group will work with you design a high-quality solution that’s tailored to your household’s specific heating requirements. We can arrange an initial consultation over the phone, and then book you in for a no obligation free technical survey with an experienced ASHP engineer.

Is there funding for Air Source Heat Pumps?


Yes, there is funding available. In October 2021, the Government unveiled the Boiler Upgrade Scheme. Families will receive £7,500 per household to change their gas boiler to a heat pump.

With the average installation price starting from £7,000, this scheme makes ASHP’s a great, cost-effective heating solution. In addition, the eco-friendly scheme reduces the average installation fee to just £2,000, making it cheaper than a new gas boiler.

Service & Maintenance


We recommend regular servicing and maintenance of your Air Source Heat pump; this can help prevent breakdowns and prolong the lifespan of your heat pump and for your ASHP to work at its highest performance

Air source heat pumps require minimal maintenance and have a general lifespan of twenty years.

We also will carry out repairs and maintenance on ASHP not originally installed by Sunlite Group.

What are ASHP’s


Air source heat pumps are low-carbon, renewable energy sources. Their environmentally friendly technology can heat your home using natural ambient air from outside, even in cold weather.

There are two types of air-source heat pumps, air-to-water and air-to-air. Air-to-water systems are the most common as they extract heat energy from the air outside and use it to heat water stored in a tank. In contrast, air-to-air pumps use fans to distribute warm air around your home and cannot heat water.

How do they work?


Air source heat pumps use the same technology as your refrigerator, in reverse. 

  • Evaporator – as the air flows over the network of tubes filled with a refrigerant, this refrigerant will gradually heat and transform from a liquid to a gas (vapour).
  • Compressor – an electrically powered compressor compresses the refrigerant vapour, increasing the temperature so that it’s high enough for use.
  • Condenser – This warm refrigerant passes into a heat exchanger, which condenses the vapour into a high-temperature liquid. This liquid will move through your chosen heating system, e.g. underfloor heating, to warm your home.
  • Expansion Valve – Once the liquid refrigerant passes through the expansion valve, its temperature & pressure will slowly decrease, and the cycle repeats.

Renewable, Green energy


It’s more important now than ever to look for more sustainable living methods. By installing a heat pump, you can help reduce your carbon footprint and cut down your energy bill.

  • Reduce your carbon footprint with sustainable energy
  • A little goes a long way – heat pumps only need a small amount of electricity to complete their energy absorption & distribution process. 
  • Low maintenance – requires minimal cleaning every two months and an annual service.

Can a Air Source Heat Pump replace my boiler?


Absolutely. In most cases, an air source heat pump can provide all the heating and hot water required for your home. As it uses 65-70% of ambient air found naturally around your home, it is a far more economical solution than the standard gas condensing boiler.

The ideal home will be well-insulated with a garden to accommodate the pump itself. Air source heat pumps work best alongside underfloor heating systems or radiators with a large surface area. You must also have adequate internal space for the hot water cylinder.

The heat is emitted at a lower temperature than gas and oil boilers, so you may need to run the heat pump for longer periods to reach your desired temperature. However, a well insulated home will reduce this time significantly.


What are the running costs?


For every 1 kWh of electricity, air-source heat pumps can produce 3 kWh of heat


For every 1 kWh of electricity, air-source heat pumps can produce 3 kWh of heat. The average UK heat demand (12,000 kWh) divided by three results in a requirement of 4,000 kWh of electricity. 

If this electricity is priced at £0.13 per unit, it will cost you £520 to run per year, which averages at just £43 a month. A fraction of the cost compared to the average monthly bill of 3 bedroom house, currently standing at £97.
