The earth accumulates solar heat,
keeping the temperature
below ground at a constant 0 to 10°C
Warm in the winter
The heat pump concentrates low-grade heat
from below the ground and raises its temperature.
This heat is then transferred to the house’s energy
distribution system – unusually radiators, hydronic floor
heating or fan coils.
Ground accumulates solar heat,
so the temperature underground
is from 0 to 10ºC.
Cool in the summer
The heat pump collects heat from the house
and deposits it into the ground,
This is more cost-efficient than traditional
