R A Brown Heating Services are experts in ground source heat pump installation. If you are considering a ground source heat pump (GSHP) to provide heating for your property, we are proud to be recognised nationally for our expertise as a ground source heat pump installer across Norfolk & North Suffolk.

Properties which are suited to a ground source heat pump installation:

A ground source heat pump is a perfect solution for rural properties with no access to mains gas. Heat pumps are an increasingly attractive alternative to oil or direct electrical heating.

Ground source heat pumps are more efficient than air source heat pumps as they rely on the relatively constant heat of the soil a few feet below the surface. Ground source heat pumps are, however, not suitable for all properties and situations.

GSHP’s are ideally suited to barn conversions, many new build properties or country home renovation projects with suitable clear land.

How a ground source heat pump will save you money:

A ground source heat pump is energy efficient, working between 400 – 500% efficiency, when compared to a new conventional oil system which works at 90% efficiency. Therefore, a GSHP system delivers significant annual savings depending on which conventional system you are moving from. Switching from LPG or direct electric will see the highest financial saving, closely followed by oil.

Frequently asked questions about Ground Source Heat Pumps

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 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.

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.

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.

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.

“R A Brown advised, designed and installed out ground source heat pump and underfloor heating and continue to perform annual maintenance.  Engineers are exemplary in cleanliness and effectiveness. Top Spot!”

Mr L, GSHP Norfolk

“We had R A Brown install a NIBE 1155 ground source heat pump and from the initial visit to the final commissioning we were always very pleased with how the project was handled.  Browns consistently did what they said they were going to do, on time and on budget”

Mr J, GSHP Norfolk

“Living with a heat pump is somewhat different from burning oil or gas, but we are delighted with our warm and cosy house and massively reduced carbon footprint, let alone the RHI payment system”
