Your heat pump must be installed by a participating Energize CT rebates heat pump installer and must replace oil heat, propane, natural gas, or electric resistance (baseboard) heating as your home’s primary heating system.
If your contractor determines that a backup oil, propane, or natural gas system is to remain in the home, an integrated control must be installed.
