To determine the potential impact on utilities of residential heat pumps with oil- or gas-furnace backup heat (hybrid heat pumps), SAI modified its seasonal performance model to characterize the hybrid heat pump's energy consumption and costs, then used the bin method to determine the seasonal space-heating energy costs for hybrid and conventional heat pumps, oil and gas furnaces and electric-resistance furnaces for sets of weather data for 12 locations. Life-cycle cost calculations showed that a significant market exists for hybrid heat pumps as retrofit units (for replacing air conditioners in systems having adequate ductwork) or as new units in winter peaking areas where natural gas is scarce. The load-management savings that would result from peakshaving would economically justify a utility's giving rebates to customers who install new units.
