Ground Arrays and Boreholes
A ground source heat pump draws heat from the ground rather than the air, using pipework buried either horizontally in trenches — often called a "slinky" array — or vertically in one or more boreholes. Ground temperature stays more stable through the year than air temperature, which is why GSHP systems tend to run efficiently even in a hard winter.
A horizontal array needs a fair amount of open ground, which suits a lot of the rural properties we work on around Goodwick with gardens or adjoining fields. Where land is limited, a borehole achieves the same result vertically, drilled by a specialist contractor we coordinate directly.
It's a bigger upfront job than an air source install, mainly because of the groundworks, but the running costs are typically the most stable of any system we fit.
