Dual Fuel Heating Systems
Energy-efficient heating and cooling for your home
A Dual Fuel system combines an energy-efficient air-source heat pump with a new or existing oil or propane furnace.
The furnace provides supplemental or primary heating in winter, avoiding costly heating charges.
In other seasons where less heat is needed, the air-source heat pump provides enough comfort to act alone.
This combination of heating sources can help significantly lower your home heating costs while maintaining the
comfort you are accustomed to with fossil fuels like oil or propane.
How a Dual Fuel system works
In the spring and fall, the heat pump extracts heat from the outside air and pumps it into the house,
warming the house more efficiently than with electric resistance heat.
However, on cold winter days and nights (below 40 degrees Fahrenheit) back-up heat from the fossil fuel
furnace is used because the heat pump simply does not provide the same comfort.
Then in the summer, the heat pump reverses its cycle and acts as a central air conditioner,
extracting heat from inside your home and pumping it outside. During the summer season,
the heat pump acts as an air conditioner and both cools and dehumidifies your entire house.
By replacing old, inefficient systems, you can reduce your energy use and your energy bill by up to 30%.
