Got Heat?

Heating is the single largest use of energy in your home. Find out how to tune up existing units and about incentives for buying new units.

Heating is the single largest use of energy in your home.  

Heaters use electricity for the fan, and fuel for the heat, typically either electricity or gas. With proper maintenance, you can reduce your bills while increasing your comfort. Replacing old units with new efficient ones, or switching fuels, can drastically reduce your energy consumption and your share of power plant pollution. 

Choose your fuel

Consider switching to natural gas. Natural gas heat is roughly 60% more efficient than electricity. Moreover, since one half of Idaho's electricity comes from coal, switching to gas directly reduces your carbon footprint.

The sun's rays are free. Three simple measures can help.  First, clean windows let in more light, so grab a rag and give 'em a wash. Second, open your curtains during the day and close them at night. Third, use dark colored tile or stone floors in sunny windows to gather heat. For the more ambitious, check out some remodel ideas.

If you use a wood stove, make sure it is safe and ready for the winter. Get your chimney cleaned. Check the door seal. Use an EPA certified stove, which emits fewer emissions while producing more heat.

Pump heat instead

A heat pump moves heat rather than creating heat. Using air, water, or the ground as its heat source, it provides you with up to four times the energy it consumes. Especially if you use electricity for heating, changing to a heat pump can reduce your energy consumption by 30 - 40%.

Ground source heat pumps are the most efficient and comfortable systems available. They qualify for a federal tax credit of 30% with no cap until December 31, 2016. Idaho allows up to $20,000 of tax deductions over four years.

Improve your heater in three easy steps.

  • Change the air filter. During the heating season experts recommend you change the filter each month to improve air flow and indoor air quality.

  • Clean your unit. Open up your furnace and vacuum out the dust and cobwebs from the controls and the fan blades.  For electric units, vacuum any dust off the coils. If you see a belt between the fan and the motor, check the tension — if there is more than 1/2 inch of sag, then replace it. 

  • Check the performance. For natural gas units, turn on the thermostat then go look into the unit. You should see steady blue flames. If not, call a professional.
