- Heat pumps generally perform less efficiently at low ambient outdoor temperatures than they do at moderate ambient outdoor temperatures. In the January 2023 RFI, DOE expressed awareness of HPs that combine the operation of a conventional electric HP with a back-up heating source, such as a fuel-fired furnace or boiler. 88 FR 4091, 4106. These are referred to as “dual-fuel” systems or hybrid heat pumps (“HHPs”) and provide an alternative to heat pumps specifically designed to perform in cold clim · public-inspection.federalregister.gov
