Dual Fuel Heating System

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 a 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.

For more information about the Duel Fuel Heating program, please e-mail us. For additional heating and cooling rebates, visit our Earth Connect program page.
