An air-to-water heat pump takes its heat from the outdoor air which means that it does not need any collector circuit but still ensures great savings.
This system transfers heat by direct vaporization when air passes through a heat exchanger. Even cold air contains sufficient heat to vaporize a refrigerant.
There is no need for bore holes and ground collectors so installation is quick and simple and can be installed in any type of house.
This also means that the air-to-water heat pump is a perfect and highly efficient solution for areas where it is not possible to drill for rock heat, or where the garden is too small to install a conventional heat pump collector system.

1. |
Fan/Evaporator takes heat from the air to boil the refrigerant at low temperature. |
|
2. |
The refrigerant is then compressed in the compressor, causing the temperature to rise. |
|
3. |
The heat is given off to the hot water and heating system in the condenser. |
|
4. |
Heating and hot water pump. |
|
5. |
The expansion valve controls the pressure in the refrigerant circuit. |
|
6. |
Cold refrigerant re-enters the evaporator. |
Free fuel from nature
The air-to-water heat pump produces far more energy than it consumes. For every kilowatt-hour purchased you receive a free contribution from nature comprising a further three to four thermal kilowatt hours, which are available as heating capacity.

How Air Source Heat Pumps Work
An air source heat pump system works using the process of refrigeration. The refrigeration system found in an air source heat pump is made up of a compressor along with two copper tubing coils, one situated inside the building and one outside; to help in the transfer of heat aluminum fins surround each coil. In the process of heating the outside coil extracts heat from the air (source) through a refrigerant contained in the coil which in the process evaporates the refrigerant liquid into a gas. Condensing the refrigerant back into a liquid the indoor coil releases heat from this very process. Turning air source heat into home heating and hot water is just that simple!
Heat Pump solutions for Ireland’s summer and winter!
With air source heat pumps the advantage to the home or business is enjoyed all year round. The truly clever part of using an air source heat pump system is that the whole heating process between air source and home or business can be reversed by use of a reversing valve which can change the direction of the refrigerant flow to either cool the building in the heat of summer or warm things up nicely in the colder months!
