Heat pump heat, in the wilderness or otherwise, is about 4x as efficient as resistance or fire.
This is somewhat silly, since a gas-fired heat pump can be very efficient, but gas-fired heat pumps are quite rare.
(California has a pricing/policy problem here, IMO. Electricity is absurdly expensive, gas is somewhat reasonable, and the result is that electric heating is not nearly as economical as it should be.)
- semi-extrinsic 3y agoGas-fired heat pumps are neither economical nor efficient for single-apartment or single-house systems. Internal combustion engines with shaft power output of 1-2 kW are inefficient, loud and maintenance intensive. They can start to make sense from around 50 kW heating/cooling capacity and upwards, so the smallest units are suitable for 8-15 apartments depending on size.
