Energy efficiency made easy.

You're off to a great start by heating with Bioheat®fuel!
Now let’s see what else you can do to improve on your home’s energy efficiency and reduce your heating costs.


  • Vacuum registers and vents regularly, so they move heat more efficiently.
  • Move furniture and drapes that may be blocking heat sources, allowing the heat to move more easily.
  • Close curtains and blinds at night to keep the cold air out, but open them during the day to let the warm sun in.
  • Keep closet doors closed. Closets don’t need to be at the same temperature as the main rooms of your home.
  • If you have rooms that you only use occasionally, like a guest room, close and seal off the vents in those rooms. This will direct the flow of air to the rooms you use most.
  • Move quickly in and out of your home. Each time you open the door, cold air is entering your home and the heat inside is rushing out.
  • Wash your clothes in cold water and only wash full loads of clothes.
  • In cool months, run your fan in a clockwise direction to push the heat down from the ceiling.
  • Turn your thermostat down during sleeping hours. Consider investing in flannel sheets and a warm comforter for your bed to keep you warm at night.



  • Schedule a heating system efficiency check at least once a year. Improving the efficiency of your heating system by a couple of percent points can bring significant cost savings.
  • Seal air leaks around windows and doors with stripping and caulking. It will help reduce the heat that you may be losing, while also making your home more comfortable.
  • Install insulating window treatments. Cellular and honeycomb shades will help you reduce heat loss.
  • Clean or change filters regularly. A dirty furnace will slow down air flow and make the system work harder to keep your home warm.
  • Electrical outlets and switches on exterior walls can be very drafty because insulation isn't always placed behind and around them correctly. To stop the leaks, remove the cover plates and fill small gaps around the boxes with acrylic latex caulk.
  • Insulate pipes on or near outer walls with foam-rubber pipe insulation. Not only will it keep the warm air in, it will keep mice and insects out.



  • Insulate, insulate, insulate! Have a professional evaluate your exterior walls, crawl spaces, attic and ceilings to see if your home has the recommended amount of insulation.
  • Have a programmable thermostat installed. It can adjust your home’s temperature throughout the day, lowering the temperature when you’re not there and bringing it back up so it is nice and comfortable when you arrive.
  • Upgrading to a new heating system is perhaps the best way to save money on your energy bill. Today’s systems are cleaner, quieter, heat your home more evenly and take up a fraction of the space than an older system. A new system can increase the value of your home, too!

  • Add storm doors to your home. This outer door is a defense against wind by trapping air between the doors, an effective insulation barrier.
  • Certain trees and shrubs can block winter winds and help reduce wind chill. A landscaping professional should be able to guide you based on the size and terrain of your property.
  • Reduce your heat loss from the fireplace. Have a professional check your fireplace and chimney to ensure you are not losing excessive heat when not in use.
  • Replacing your windows can greatly improve energy efficiency. In the cooler months, new windows will help keep the cold air out of your home and the heat in.
