Abstract
An indoor space heating apparatus comprising a heat pump including indoor and outdoor heat exchangers in fluid communication with a heat pump compressor. A blower is positioned to blow air over heat rejection coils of the indoor heat exchanger and into an indoor warm air reservoir. A combustion engine drives the heat pump compressor and a furnace transfers combustion heat from the combustion engine to the indoor warm air reservoir.
