DUAL FUEL

Warm your winters, cool your summers and pocket hot savings with Dual Fuel.
Enjoy comfortable heat in the winter and refreshingly cool air in the summer with an add-on electric heat pump. The heat pump works with your oil, gas or propane furnace to provide heat in the winter and becomes a central air conditioning unit in the summer.

How your heat pump heats
1. First, heat is absorbed from cold air outside by a low temperature, low pressure refrigerant.
2. The gaseous refrigerant then passes through compressor & is compressed into a high temperature, high pressure vapor.
3. As refrigerant passes through an indoor coil, heat is transferred to indoor air and the refrigerant condenses to a liquid.
4. Warm air is then circulated throughout your house.
5. The liquid refrigerant returns to the outdoor coil where it once again becomes a vapor and the cycle starts over.

How your heat pump cools
1. Heat is absorbed from inside air by a low temperature, low pressure refrigerant in the indoor coil.
2. Cool, dehumidified air is circulated in the house.
3. Heated gaseous refrigerant flows to a compressor, which then raises the pressure & temperature of the gas & pumps it to the outdoor coil, where heat is transferred to outdoor air.
4. Refrigerant condenses into a liquid in the outside coil as heat is given off.
5. Liquid flows back to the indoor coil where it vaporizes, & the cycle starts again.

Darke REC Dual Fuel Rebate Program Requirements
You can qualify for a $600 rebate if you install an add-on electric heat pump unit to an existing fossil fuel furnace.

Effective January 1, 2007 Darke REC will no longer offer the 1-1/2 cent/kwh incentive for new add-on heat pump installations.

Any installations prior to January 1, 2007 that already receive the 1-1/2 cent/kwh incentive will continue to receive it through December of 2010.

The rebate program will be reviewed each year to determine its continuation.
