Ground Source Heat Pumps with Bore Hole
A geothermal heat pump which extracts the heat through a loop passing through a bore hole or multiples of bore holes anything up to 180 metres deep, you require 66 metres of pipe work per kilowatt. Good summers are not that important with this system as the bore hole passes through a larger mass resulting in a fast recovery, but you can also help to put the heat in by fitting passive cooling within the property, which extracts the heat during the summer periods and discharges it back into the ground.
Advantages
Ground Source Heat Pumps with Loop 1m Underground
A heat pump which extracts the heat through a loop passing approximately 1 metre underground. You require 66 metres of pipe work per kilowatt. You rely on the sun during the summer periods to heat the ground back up again, but you can also help to put the heat in by fitting passive cooling within the property, which extracts the heat during the summer periods and discharges it back into the ground.
Advantages
The co efficiency of performance or COP of a heat pump is the ratio of the output heat to the input supplied, example, one kilowatt of energy used produces 4 kilowatts. The air unit is more efficient in the summer than the winter, but on average it works out at a COP rating of 3.2 to 4.5. Below is an average cost per kWh for the main fuels, when calculating the heat pump one needs to divide the kWh by the COP example 10p per kWh peak divided by a COP of 4 equals 2.5p per kWh; off peak is 1.4p per kWh.
