Heating is the single biggest energy use in homes. A well maintained heating system will hold down fuel costs and provide reliable comfort.
Thermostats should be located on an inside wall or where they will not be subject to draft or heat.
Use door snakes to reduce drafts.
Block off your open fireplace when not in use.
Capture as much sunlight as possible.
Close curtains before dark to keep heat in.
Use and extra blanket if a bit cold.
The many small openings in a home can add up to big heat losses. Caulking and weather stripping cracks in walls and floors, windows and doors will save fuel and money.
Use ceiling fans to distribute the heat throughout your home.
Proper insulation in walls, ceilings and floors also significantly reduces the loss of heat to the outdoors. Insulation will pay for itself in fuel cost savings and home comfort.
Storm windows and doors are big energy and money savers. They can reduce heating costs by as much as !5% by preventing warm air from escaping to the outside. Double glazed and thermopane windows can minimize heat escape.
