Ground Source Heat Path - Trench

At depths of 2m and more the ground temperature does not deviate very much from the average summer/winter surface temperatures (around 8° to 12°C in the UK depending on location).

Ground source heat pumps absorb this heat energy stored in the ground at depths from just 1.2m (for slinky ground arrays) to around 250m (for borehole ground arrays).

Ground source heat pumps absorb the heat energy stored in the ground or water via ground arrays or ‘collectors’.
