Heat Your Home For LEss

Thousands of UK households are already benefiting from reliable, renewable heating with Ecodan air source heat pumps. Ecodan air source heat pumps can lower your energy costs, lower your carbon emissions and make you eligible for Government grants including the Renewable Heat Incentive (RHI) payments.

Free Energy

Ecodan air source heat pumps are classified as a renewable energy source because they capture free energy from the air. This makes them a great solution for gas boiler replacement and oil boiler replacement, and an alternative solution to biomass. Ecodan works by sitting outside your home and extracting warmth from the outdoor air. Ecodan technology upgrades this renewable heat energy and transfers it inside the home to provide energy efficient hot water and heating for radiators and / or underfloor heating.

Air Source Heat Pumps

An air source heat pump is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump needs electricity to run, but it should use less electrical energy than the heat it produces.

There are two main types of air source heat pumps (ASHPs): air-to-water and air-to-heat. An ASHP works a bit like a refrigerator in reverse.

The process consists of an evaporator, a compressor and a condenser. The ASHP absorbs heat from the outside air into a liquid at a low temperature, then the heat pump compressor increases the temperature of that heat. In the condenser, the hot liquid’s heat is transferred to your heating and hot-water circuits. So you can use it to warm up your home.

Air To Water Heat Pumps

These take heat from the outside air and feed it into your wet central heating system. As the heat produced is cooler than that from a conventional boiler, you may need to install larger radiators or underfloor heating in your home to make the most of it. They qualify for the Renewable Heat Incentive (RHI), too. Under the UK government’s scheme, you could get money towards renewable heating costs in your home. Air-to-water heat pumps may be the answer to increasing fossil fuel prices. It could cost less if the heat pump is included as part of the building specification, rather than having to retrofit underfloor heating later on.

Air To Air Heat Pumps

These pumps take heat from the outside air and feed it into your home through fans. This type of system cannot produce hot water. Installing an air source heat pump, they look similar to air-conditioning units. They are less disruptive to install than ground source heat pumps, as they do not require any digging in your garden. They are also cheaper than ground source heat pumps.


Simply put, a heat pump is a device that transfers thermal energy from one point to another. A common example of this can be found in our refrigerators where the evaporation and cooling of a liquid is used to lower the temperature of the storage compartment. Nowadays, this technology can also be used to extract the potential thermal energy in the air outside, or even from the ground, feeding it directly into your home where it is compressed and the heat transferred using a series of coils.

Yes. A correctly sized heat pump will provide all of a home or business space heating & hot water on demand. Our specialist installers can advise you on the correct size pump for your home or office.

Energy bills can be reduced by up to 90%. Customers who currently use oil, LPG or direct electric will see the largest savings.

Yes. We have seen that electricity bills will on average rise by 10% but compare that to the amount you’ll be saving you’ll be quids in.

If you currently use solar panels then they will power your air source heat pump.

The air to water system works by distributing heat by means of your wet central heating system. The heat pumps tend to work far more efficiently at a lower temperature than your standard boiler, which makes them more suitable for use with underfloor heating or large radiators. Both of these give out heat at a lower temperature you see, as well as doing so over a longer period of time.

The air to air systems works to produce warm air that is circulated by fans in order to heat your home. Usually, they are only used for one function, which is most commonly electricity. They are, in fact, highly unlikely to be able to provide you with multiple functions such as electricity and hot water.

Heat Pumps provide heat most efficiency when running all the time. By providing heat over longer periods of time, an air source heat pumps demand is kept low, as opposed to traditional systems where large amounts of heat is emitted in short blasts. This method actually reduces running costs & results in a comfier living environment.

The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help the UK reduce its carbon emissions and meet its renewable energy targets.
