Heat Pumps
Up to 400kW using Stiebel-Eltron
Fit and forget renewable heating system
Heat pumps require the lowest amount of maintenance and servicing of any renewable heating system
Ground Source Heat Pumps extracting heat from the ground
A ground source heat pump collector can be horizontal if space is available or verticle in boreholes if space is limited.
Water Source Heat Pumps for highest efficiency (COP)
When there is a river or a lake, using this for the collector provides reduced installation costs and increased performance.
About Heat Pumps
Heat pumps work by extracting heat from the environment. This may be from the air, the ground or from a watercourse.
This heat is then put through a compressor to increase its temperature.
It is an efficient and reliable source of heating because the electricity that is used to run the compressor can create approximately 4.5 times the amount of kWh of electricity it has used to operate as heat.
There are three common types of heat pumps:
- Ground Source Heat Pumps
- Extract heat from the ground using horizontal loops or boreholes
- Water Source Heat Pumps
- Extract heat from a watercourse such as a river, lake or pond. This can be done in a closed loop system using coils placed in the water, or through an open loop system which passes the water over a heat exchanger.
- Air Source Heat Pumps
- Extract heat from the air, by using a fan to block ambient air over a large heat exchanger.
