Ground Source
Heat Pumps
Ground source heat pumps take heat from
the ground and convert it into energy. Radiation from the sun heats the
earths’ surface. The earth stores this heat to a constant temperature
of around 8-12 oC even in winter time. This converted energy
can be used to heat buildings and supply hot water. For every 1 unit
of electricity used, 4 units of heat are produced. Thus, 75% of usable
energy arrives free the other 25% comes from the electricity used to
power the heat pump. The heat pump removes stored solar energy in the
earth around a building, compresses it to a higher temperature and
transfers it to the central heating system and hot water storage tank.
Air/Water
Heat Pumps
This equipment converts the outside air
into heat energy for domestic and commercial uses. Where it is not
possible to drill a bore hole or dig a trench for ground source energy,
or install any form of surface absorber on the property, the air/water
heat pump is a good alternative.

Using the soil, bed rock or groundwater as the heat source All around us are sources of energy in the form of stored solar energy, which even if they have a low temperature can provide us with heat. But how can a few degrees above zero gives us energy to heat radiators and hot water. Example of Water Heat Pump

Down in the bedrock there is a source of heat that stays at practically the same temperature all year round. Using heat from the rock is a secure, safe and environment-friendly way of heating all types of building, large and small, public and private. The capital cost is relatively high, but in return you get a reliable, low-energy form of heating with an extremely long life. The coefficient of performance (COP) is good, as high as 4.8. The plant occupies little space and can even be installed on small plots. Very little reinstatement work is needed after drilling the borehole, so the effect on the nearby environment is minimal. The groundwater level is not affected, since no groundwater is used. The heat energy can be transferred to an existing, conventional, water-borne heating system and can also be used to produce hot water. Example of Ground Source Heat Pump with boreholes
