The Emerald People’s Utility District (EPUD) says for every two-degree drop outside, your heating system–electric, natural gas or wood stove–is working 6 percent harder to maintain heat.
How energy efficient your home is will impact your heating bill.
For a 1,600 square foot residential home that uses a heat pump, EPUD says it will costs 63 cents an hour to maintain your home at 65 degrees when it’s 28 degrees outside. When it’s 34 degrees outside, that drops to 53 cents an hour. When it heats up to 45 degrees, it’s much more efficient, just 15 cents to heat your home per hour.
