Heat Pump systems can heat a home for less money than gas heating because typically 85% of the heating needs come from first stage heating.
Dual fuel systems have first stage heat pump heating systems with second stage gas heating – which replace traditional heat strips. This can be package or split system with propane or natural gas.
New system installations may qualify for up to $500 rebates through Berkeley Electric Cooperative’s Dual Fuel program.
You can also receive a $500 rebate when you replace gas heat with a dual fuel system (limit one rebate per home).
