2 KW output geothermal heating module was integrated in to Compact P and was connected to a zoned underfloor heating system as back up to Air-to-Air space heating system. This was only switched on for 3 months and operated in hallway and a bathroom , however, at all times the warm air heating was primary heating source.

There was no stove installed in the house, so all energy consumed was relating to electrical consumption.

The interesting fact from 2 years of monitoring, the summer by-pass valve was open for 46% of the time meaning that the house was in a ventilation mode. At least the Compact P can produce domestic hot water from exhaust air and not all the exhaust energy was wasted as you would typically find in standard MVHR unit.
