A modern heat pump claims a cop in the 4.8 range
It’s more efficient to burn the gas in a grid power station, convert to electricity, and use the electricity to drive the heat pump, then it is to burn the gas for heat directly.

- yvdriess 4y agoWatch out, cop ranges wildly (1.1-5+) depending on the type of heat pump, output temperature and intake temperature. Ideal are water-water heat pumps connected to a deep well, but these cannot be installed everywhere and carry a significant (roughly double) capital investment. Air-water heat pumps are very sensitive to outside air temperature and output temperature. Low-temperature heating (30-40C) still gets an OK ~2-2.5 cop in freezing temperatures, but sanitary water (65deg C) tanks the efficiency significantly. Another consideration is that you lose efficiency in converting chemical to electrical energy, plus there is a higher transport and distribution loss to factor in.

Show a 4.5 cop for a 7C-35C range, dropping to 1.8 for a -7 to 55C range. For 2C to 35C it’s still a cop over 3
