Ground Source Heat Pumps

About

Ground source heat pumps (GSHP's) take heat energy from the ground and convert it into hot water for domestic use and central heating. Using the same principles as ASHP's, energy is used to transfer heat energy from the ground to the water inside.

Contrary to some beliefs, they do not work on geothermal energy (which needs hot rocks or springs), rather the energy stored in the ground from the sun. Compared with ASHP's, GSHP's can work at slightly higher flow temperatures however can still be thought of in the same way.

Depending on your current fuel could be seeing a

30-60% reduction in heating costs!

Efficiency

For every 1kW of electrical energy used, a total of ca. 4kW of heat energy is generated. This means GSHP systems have a SPF (seasonal performance factor) of 3.4-4.3, which is a 340%-430% increase in energy.

Where

There are two main types of GSHP: Bore hole, a more expensive option, envolves drilling down in to the earth 100m or more at a suitable location close to the property; Ground loop systems, a more economical option, envolve digging trenches, apporximately 1m by 1m, in a larger expanse of land ideally close to the property - e.g. a small paddock or large garden.

There is a third - however less suitable for our local area - type of GSHP called water source. This collects its heat from a flowing body of water, such as a lake.

Why

They cost more to install than traditional heating systems and much of this is due to the ground works that are necessary. However, their low running and maintenance costs, coupled with a life expectancy of over 20 years, make them an impressive long term investment.

Cost

Due to the individual nature of each home, a unique installation package needs to be designed for each property. To do this we offer a FREE non obligatory survey and quotation.

Each survey takes into account variables such as size, energy efficiency and desired usage of the house.
