Drilling boreholes in front of Cambridge Terrace with a view towards Chester Terrace.

Interseasonal Heat Transfer (IHT) recycles heat from Cambridge Terrace down to a ThermalBank in summer as it cools the building.
IHT uses a heat pump to recycle heat back to the building in winter to provide heating without burning fossil fuels.
IHT doubles the Coefficient of Performance of the heat pump by starting from a warm ThermalBank.
