Dual Fuel or Hybrid Heating

Dual Fuel, Add-A-Pump, or Hybrid Heating… which is it?

They are virtually the same thing.  The terms are used by people in the HVAC (Heating, Ventilation, and Air Conditioning) industry to describe a system that uses a Heat Pump (either Air to Air or Geothermal) in conjunction with a Gas Furnace (either Propane or Natural Gas) to heat a home or business.

This type of system removes the main complaint people have said about heat pumps forever, it eliminates the cool air in the coldest part of the heating season.

Depending on the price of Gas (either Propane or Natural Gas) and the price of Electricity, the system can be setup to take the greatest advantage of the market pricing.


We have installed them for many reasons over the years:

They Provide the Warm Air that people are looking for.

They Help homeowners save money on Propane – cutting gas usage by over half in many instances.

They can use an existing Gas Furnace, such as when an air conditioner goes out, but the furnace is relatively new – saving money on installation costs.


Performance of a heat pump is affected by the weather, the warmer it is outside the more heat a heat pump puts out (relative to the amount of energy it uses, often 3.5 to 4 times as much).  It's a little over simplified here, but the best furnaces are in the 96% range – not a multiplier effect like the heat pump.

In the Southern Kentucky area, we often see Balance Points, the temperature at which the furnace needs to take over for the heat pump, at 35 degrees… allowing the heat pump to produce lots of heat, efficiently anytime the outside temperature is above 35 degrees (they also put out VERY warm air above 35 degrees… new Heat Pumps by Trane put out warmer air than heat pumps of years earlier).

Pictured is another installation by Gra-Tac Heating & Cooling, Bowling Green's Trane Comfort Specialist Dealer.  This installation of a Trane XB13 Heat Pump – 13 SEER, replaced a Payne Air Conditioner of 10 SEER, when the compressor went out on the Payne Air Conditioner.  This allowed the home owner to keep from buying a new furnace, since it was already over 90% efficient, still covered by the manufacturer's heat exchanger warranty, and means $,$$$ saved upfront on installation costs.
