Ground source heat pumps: the economics?

This data-file models the economics, costs, energy savings and potential CO2 savings of a ground source heat pump (GHP), compared to traditional home heating and cooling options.

A GHP approximately doubles the efficiency of conventional heating and cooling, through heat-exchange with the shallow earth, 30ft below the surface, which tends to remain at 10-15°C temperatures year-round.

The model can be stress-tested, flexing annual heating/cooling demands, coefficients of performance, as well as oil, gas, power and CO2 prices. Also included are a granular cost build-up for CHPs and our notes.
