Not sure how the EHPA calculated it, but heatpumps are more efficient heaters than gas boilers in any case, so they would save gas even if the electricity is gas based (which won’t be, as nearly 3/4 EU electricity is carbon free [renewables incl biomass, nuclear], already)

@Akshay@eupolicy.social You are correct that heat pumps are quite efficient heaters. To a first approximation the efficiency of a heat pump almost cancels the inefficiency of a nat gas turbine. The result being that if that turbine is supplying the electrons to the heat pump the CO2 being released is the same as if the nat gas was combusted in a boiler/furnace. In most of the datasets I’ve studied the seasonal renewable supply slumps mean they can’t be counted on to supply heat pump heating. In Ontario nuclear supplies most of my winter GSHP electrons, but that level of nuclear penetration is rare on a global scale.
