In most cases, Dual Fuel means combining a high-efficiency heat pump with a fossil fuel furnace (natural gas or propane). The heat pump will meet the heating and cooling needs of the typical home economically down to 15°F. At that point, when the efficiency of the heat pump is dropping off and when Boone Electric is reaching peak demand for electricity, an outdoor thermostat shuts off the heat pump and turns on the fossil fuel furnace. When the temperature rises to 16°F - 18°F, the gas furnace shuts off and the heat pump will again supply the heat.
In order to help control our summer peak, we'll install a load control switch on the heat pump to cycle the compressor on and off. Heating and cooling your home at the highest efficiency will decrease demand on our electrical system. Historically, when temperatures fall below 15°F or rise above 95°F, the co-op approaches a peak electricity demand.
If we can reduce the demand or hold it steady with programs like Dual Fuel, the result will be more stable electric rates for you. Read more about Dual Fuel rebates.
