Summary

Direct combustion to generate heat is never the most efficient use of fuel. Heat pumps are more efficient because they use renewable energy in the form of low-temperature heat. If the fuel used by conventional boilers were redirected to supply power for electric heat pumps, around 35% less fuel would be needed, resulting in 35% less emissions. Nearly 50% savings are made when electric heat pumps are driven by combined heat and power cogeneration systems. Whether fossil fuels, nuclear energy, or renewable power is used to generate electricity, electric heat pumps make far better use of these resources than do resistance heaters. The fuel consumption, and consequently the emissions rate, of an absorption or gas-engine heat pump is about 35% less than that of a conventional boiler.
