Ground Source

Grants and Tariffs - For an ground source heat pump installation there are grants available of £1200.00 for private dwellings if applied for before the end of March 2012, plus phase two of the renewable heating incentive which is due to start in October 2012, as yet we have no details of the tariff to be offered. For more information please contact us for a free quotation and energy assessment.

Commercial installations are eligible for phase 1 of the renewable heating incentive, this also includes district heating (e.g. more than one property being heated by on source), and this can be a house with an annexe, a small office and private dwelling, or a small group of houses. The tariff is 4.5p per kilowatt hour with the average size detached house using between 35 to 40,000 Kilowatt hours per annum, this is available now and runs for 20 years.

Ground source heat pump 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 meters deep, you require 66 meters of pipe work per kilowatt. The good summer are not that important with this system as the bore hole passes through a larger mass resulting in a fast recover, 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

• Unlike water source there are no annual fees etc. etc.
• You can cool your house really cheaply in the summer periods
• You can heat your house efficiently and cheaply in the winter with a COP rating of 4.5 to 5
• It runs a lot quieter than the air to water system
• Minimum amount of disruption
• No evidence of the disturbance to the ground when the job is complete

Disadvantages

• It is expensive to install
• If you require multiple holes the distance between is a minimum of 15m
• In most cases your domestic hot water cylinder will have to be replaced with a tank within a tank system

Ground source heat pump with Loop

A heat pump which extracts the heat through a loop passing approximately 1 meter underground, You require 66 meters 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

• Unlike water source there are no annual fees etc. etc.
• You can cool your house really cheaply in the summer periods
• You can heat your house efficiently and cheaply in the winter with a COP rating of 4 to 4.2
• It runs a lot quieter than the air to water system

Disadvantages

• It is expensive to install
• Large disruption to your property
• Possibly not enough land for your needs
• There will always be evidence of where the loop is situated as this portion is always cooler and the grass/ground will be a different colour
• If the summer is poor the ground will not heat up so the return brine is at a lower temperature reducing the COP
• The area must be kept clear, no roads, pathways, patios, trees etc can be put in or around the area
• In most cases your domestic hot water cylinder will have to be replaced with a tank within a tank system
