Heat Pump: Part 2 - ground loop installed!
Amongst the generous mix of mud, scaffolding and construction materials we're relieved to have the 300m of 40mm diameter heat pump 'collector' pipe safely buried 1.4m underground. This photo from the upper scaffolding shows the end result in the middle distance which should re-vegitate over next spring.
We are very fortunate in having an ideal location for this collector system, being on gently sloping ground with a high water table. This will ensure that that low grade 'heat' taken out of the ground will be quickly replenished by this water movement under the ground at pipe level, with heat transfer aided by the sand used to protect the pipe aganst sharp rocks when backfilled.
