Costs and Outputs
Ground Source Heat Pumps
Complete System Prices
As a general guide, the cost of installing a GSHP heat pump system for a well insulated, domestic property is likely to be between £6,000 and £9,000. This approximate price includes the supply and installation of a horizontal ground loop, heat pump and buffer cylinder. A typical domestic ground source system will have a heat output of around 5 kW and cost of approximately £1 250/kW.
Running costs
The efficiency of a GSHP system is measured by the Coefficient of Performance (CoP). This is the ratio of the number of units of heat output for each unit of electricity input used to drive the compressor and pump for the ground loop. Typical CoPs range between 2.5-4. The higher end of this range is for underfloor heating, because it works at a lower temperature (30-35oC) than radiators.
The best gas condensing boiler has a seasonal efficiency of approximately 85% compared with an efficiency of about 73% for a conventional boiler. Heat pump systems however can operate at seasonal efficiencies greater than 100% and an efficient GSHP will operate with a seasonal efficiency of at least 300%.
Air Source Heat Pumps
A typical 6 – 8kW system costs £6,500 – £11,500 (not including the price of distribution system). This can vary with property and location. On average you can save £650 – £750 on your heating bills and 4.5 – 5.5 tonnes of C02 per year. Enviko sources all its heat pumps from reputable manufacturers including Thoré, Nibe and other top leading names.
All Quotes are prepared individually for each system, without charge and without obligation. This can be done upon receipt of building plans, showing room layout and dimensions, and a site plan. For existing buildings we also require a calculation of heat loss.
Orders are to be confirmed in writing and customers will then be invoiced for 30% of the total order cost. The remaining costs will be settled 2 weeks prior to the commencements of works and upon the successful commissioning of the system.
Please remember that VAT incurred for the purchase of most structural and integral materials used in building a new home or converting a non-residential building into a residential building (e.g. a steading) can be reclaimed. Ground Source Heat Pumps are included in this, and VAT on these is charged at 5%.
