Whole-system GSHP expertise
Ground source servicing goes beyond the heat pump
A GSHP installation includes the source circuit, heating circuit, circulation, controls and often buffer and hot-water equipment. Faults and poor performance need to be considered across the complete system rather than treating the heat pump as an isolated appliance.
Hydraulics & vessels
System pressure, pumps, filters, air vents, expansion vessels, buffer vessels and heating circulation can all influence reliable operation.
Controls & hot water
Controller settings, heating operation and relevant hot-water equipment can be reviewed as part of appropriate servicing and fault investigation.
Documented experience

We do not rely on generic claims. Our NIBE F1145 project documents genuine GSHP servicing experience including ground-loop protection, expansion vessels, automatic air vents, buffer vessel, underfloor-heating pressure and hot-water equipment.
