Ground source heat pumps (GSHPs) use pipes that are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden. 

Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. 
The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year. 

The length of the ground loop depends on the size of your home and the amount of heat you need. 

Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.

Benefits of Ground Source

Earn with Ecodan

In addition to low running costs, Ecodan is classified as a renewable energy source because it captures free energy from the air.

For every 1kW of electrical input power, Ecodan harvests and upgrades renewable heat energy from the outdoor air to provide the home with an average of at least 3kW of heat output*. This ‘free’ 2kW of renewable energy is then eligible for seven years of payments from the RHI. With an average 3-bed family home in the UK needing around 15,000kWh of heating per year, you can quickly see how the RHI payments can really make a difference.

You can increase these quarterly payments even further by adding a Metering & Monitoring Service Package (MMSP). This makes you eligible for an additional £1610 payment over the 7 years of your RDF funding.

Added Benefits

The RHI Scheme has helped promote the growth of low carbon heating since its introduction in 2011 and the Government has continued to look for ways to enhance the Scheme.

Purchasing a Metering and Monitoring Service Package (MMSP) from your heat pump installer now makes you eligible for an additional £1610 payment over the 7 years of your RDF funding. 

An MMSP package will give you complete peace of mind that your Ecodan is working as expected and can also allow for remote diagnostics on your system, should it ever be needed.

A Wi-Fi connection is required at the property for MMSP. Wi-Fi access also enables you to control your heating from anywhere using the MELCloud remote control app.

Reduce your bills

The owners of a large family home in Essex have reduced their energy bills with the addition of a renewable heat pump to their existing heating system.

The five-bedroom detached property in Shenfield has had an 11.2kW Ecodan monobloc air source heat pump installed to meet the house’s heating requirements. With the gas boiler and Ecodan unit working independently, the home owners do not need to rely on metering to establish Renewable Heat Incentive payments.

With the house set up this way, those payments can be guaranteed by the deemed RHI calculation based on the house’s Energy Performance Certificate.

By working in this way, the initial investment can be kept low, whilst still delivering a significant contribution to savings on household energy costs.
