More Questions About Ground Source Heat Pumps

How much will the Renewable Heat Incentive (RHI) be for a Ground Source Heat Pump?

The UK Government’s Domestic Renewable Heat Incentive (RHI) is calculated by the space heating requirement of the property (detailed on your Energy Performance Certificate)and the efficiency of the heat pump that we install. You can expect payments between £2,000 – £4,500 per annum. Your specific payment will be calculated based on your individual property.

Can you retrofit a Ground Source Heat Pump into a property?

Yes, we can fit a ground source heat pump to most properties, so long as there is enough land for the pipework to be laid outside for the collector or enough area of land to drill boreholes. As an example for a 4 bedroom property with 12 radiators, you would likely need 600sq metres of land or 2 x 150 metre boreholes.

What areas do you cover for Heat Pump Servicing?

We carry out servicing work for customers in Norfolk and North Suffolk. Prices vary according to geographical area, please ask for the price at the time of booking.  Contact our service team on 01603 567595.

Do you offer Annual Servicing Plans?

We do not currently offer a servicing plan with monthly premiums. We have considered offering this service but have decided against it at the current time for the following reasons.

We need to link up with a finance company as these types of plans are an insurance policy.

We install premium quality heat pumps, and it is more cost effective for customers to pay for an annual service each year, rather than a monthly payment plan.

If you would like to book an annual service you can call our service team on 01603 567595.

How much does a Ground Source Heat pump cost to run?

Ground source heat pumps are effectively the cheapest form of heating to run. They can be 400 – 500% efficient or more.

A ground source heat pump generates 4-5 times the energy it consumes. This means that for every 1kw of electricity that you pay for, a GSHP can produce 4-5kw of heat for your home.

How much do boreholes cost for a Ground Source Heat Pump?

Boreholes are drilled to a depth of 100 – 150 metres. There can be 2 or more boreholes required dependent on the energy required for the property.

The cost of the drilling and the pipework connections with trenching back to the plant area will cost on average between £10,000 – £18,000 depending on the number of holes required.

Does my heat pump need servicing every year?

It is recommended that heat pump systems are serviced every year to ensure they are running as efficiently as possible and to maintain your manufacturer warranty. If you are in receipt of government incentive payments, there is a requirement to ensure the system is suitably maintained in good working order.

How do Ground Source Heat Pumps work?

A GSHP uses solar energy naturally stored in the ground. With a stable temperature of between 8 – 12 degrees throughout the year it is a perfect environment to extract energy from. The energy collected from either the ground or water source via collector pipes is converted into useable heat via refrigerant gases and a compressor. This useable heat is used to heat your home in the same way as a conventional boiler sends heat to the radiators, underfloor heating or hot water cylinder so it is ready whenever it is needed.

How many years will my GSHP run for?

Ground loops have an exceptionally long lifespan and are built to last 50-100 years.

Indoor components usually last up to 20 years – double that of oil or conventional gas boiler components.

Do I need a 3-phase electrical supply to run a Ground Source Heat Pump?

For ground source heat pumps that are 16kw or above, a 3-phase electrical supply will generally be required.

Will you remind me when my heat pump needs servicing?

We do contact all our customers each year to book them in for servicing, if you wish to contact the servicing team you can call us on 01603 567595.

How much does a Ground Source Heat Pump installation cost?

An example of a typical 4 bedroom property with 12 radiators, with a ground source heat pump installation will cost in the region of £28 – £30k.

How much space do I need for the Ground Source Heat Pump collector?

For a horizontal collector you will need to install pipes 1m apart and 1.2m deep in the ground. The maximum length for a loop of pipe will be 400m but depending on the size of the heat pump required you may require 2 or more ground loops. The average system will require between 600 and 1200 square metres of land. This land must be clear of trees and buildings.

I have a water borehole, can this be used for a Ground Source Heat Pump?

Water boreholes are generally only about 20 metres – 50 metres deep. A Geothermal borehole will need to be at least 100 metres deep and often more than 1 borehole is required.

Can you service “split system” air source heat pumps?

We are not able to service heat pumps with external refrigerant circuits as our Engineers do not hold the relevant qualifications to maintain this aspect of the system. You will be asked to provide full details of the make and model of your air source heat pump and if it is a make such as Daikin, we will try to refer you to another relevant company.
