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 now qualify for up to a $1000 rebate through Berkeley Electric Cooperative’s Dual Fuel program when switching from gas to duel fuel.
A $500 rebate is available to members switching from a heat pump to a dual fuel system. Both rebates are limited to one per home.
