Is a Dual-Fuel System Right for Your Portland-Area Home? Run the Numbers


A dual-fuel system is one which combines the energy-saving power of a heat pump with a supplementary oil- or gas-powered furnace. These systems provide homeowners with a buffer against sub-freezing temperatures, which vastly reduce a heat pump’s heating capacity. While dual-fuel systems are excellent for the Pacific Northwest climate, you should still crunch the numbers to see if investing in one is worth your while.

Here are some facts you should collect and compare associated with dual-fuel heating systems. Get quotes for the following:

  • If you have a natural gas or oil system currently installed, you can retrofit it to include a heat pump.
  • A new installation, including a heat pump linked to an oil- or gas-powered furnace.
  • Don’t forget the potential need to create new ductwork to accommodate the dual-fuel system. Costs should include materials and installation.

Next, consider the age of your home. If it’s an older house, you might need upgrades to ensure that safety of the electrical connections. However, remember that you may qualify for tax credits by upgrading to energy-efficient home technologies.

Remember that upgrade costs tell only part of the story. You will add to the resale value of your home by installing a dual-fuel system. It helps to consult a local real estate professional to determine the exact amount you stand to gain in this regard. Dual-fuel systems also have the potential to save you hundreds of dollars per year on your heating costs. Over time, the cost of the upgrade often ends up paying for itself in energy savings.
