Equipment costs and maintenance are also important. For more information, visit PSE.com/Refuel or call a PSE Energy Advisor at 1-800-562-1482, Monday through Friday, 8 a.m. to 5 p.m.

*Energy costs for a forced-air furnace vary depending on fuel and equipment efficiency. Heating oil and propane prices are Puget Sound area averages (heating oil $3.07/gal., propane $2.51/gal. including tax) based on a survey completed in Jan. 2013. PSE natural gas and electricity costs are averages (natural gas $1.17/therm at 68 therms/month including tax and customer charge, electricity $0.104/kWh at 1,000 kWh/month) based on PSE rates and taxes in effect Jan. 2013. Electricity costs from other utilities calculated using same method based on per kWh average for 1,000 kWh/month use at the time of the fuel cost survey (Seattle City Light-suburban $0.089/kWh, Snohomish PUD $0.089/kWh, and Tacoma Power $0.077/kWh). Heating equipment efficiencies are 70 percent for heating oil, 80 percent for propane, 90 percent for natural gas and 100 percent for electricity. 

Top Reasons to Convert to Natural Gas

  • Lower energy costs. Historically, natural gas has cost between 20 and 50 percent less than the equivalent amount of electricity, heating oil or propane. See reverse side for a complete cost comparison.
  • Comfort. Natural gas heating equipment makes for a more comfortable home. Natural gas furnaces deliver warmer air and heat up your home quickly. Natural gas water heaters can heat twice as fast as electric models, so you receive more hot water sooner.
  • Reliability. Many natural gas appliances, such as water heaters, fireplaces and stoves, will operate during a power outage so you can stay warm, have hot water and enjoy a hot meal.
  • Environmental benefits. Natural gas can be more efficient than electricity and burns cleaner than any other fossil fuels. It is also delivered directly to your home through underground pipes while heating oil is stored in underground tanks that can leak and contaminate water or soil – damaging the environment and leaving you with the clean-up costs.
  • Low-maintenance. Natural gas furnaces generally have higher efficiencies and cost less to maintain than heating oil furnaces, producing long-term savings.
  • Increased home value. Adding natural gas to your home will pay dividends when you decide it’s time to move.
  • Versatility. In addition to home heating, natural gas can be used for water heating, cooking, clothes drying, stand-by generators, barbecues, etc.
