Aren Fossil Fuels cheaper to operate than a Heat Pump using electricity?
Since fossil fuels must be burned to generate heat, they’re limited to 100% of their heat content. While some fuels produce many BTUs, they are still limited to a maximum of 100% efficiency. GSHPs use the ground as its energy source and only require electricity to run the compressor; therefore they can typically achieve 300-600% efficiencies. What that means is that even if fossil fuels are cheap to purchase, they will not outperform a properly-sized GSHP.
