Ground Source Heat Pump

GSHP’s work like Air Source Heat Pumps, absorbing heat energy from the external environment and transferring it into your hot water system. They use very little in the way of electricity, offer very short payback times and huge government grants.

What is a Ground Source Heat Pump?

A ground source heat pump works in a very similar way to the air source heat pumps, only instead of extacting heat from the air it extracts its heat from the ground. there are various different ways of installing ground source heat pumps that all depend on the ground type you have and the space you have available to you.

There are several different types of GSHP, these include bore hole, where a deep hole is dug out of an area of land and sleeved, and ground loop, where a larger area of land is dug up but only 1 metre deep, pipework is the buried at the bottom of these trenches where it can extract the heat energy from the ground and transfer it into your heating system.

Is a Ground Source Heat Pump for me?

The main requirement for ground source heat pumps is space, inside and outside. Bore holes offer a great solution to for anyone lacking spcae for ground loop systems but can be expensive, ground loop systems often require a large amount of space to dig trenches in to bury the pipework. Inside, the system requires an internal heat exchanger and a cylinder, making it suitable for retrospective installations, as the indoor unit would replace the exisiting heating system or boiler.

GSHP’s are expensive to install, so it is more beneficial if you are able to fund the capital cost upfront and benefit from the low running costs and high RHI payments.

How much will it cost?

Typically, GSHPs are more expensive than other renewable technologies to install. However, the running costs and large payments through the Renewable Heat Incentive offset this very quickly, usually within 3 to 4 years the sydstem will have paid for itself.

Ground source heat pumps are more expensive to install due to the fact that you either have to dig very deep bore holes, or dig large trenches, fill them with a ground loop and then back fill the ground again. Whereas an air source installation only requires a unit to be installed outside your home.
