Heat pump vs. furnace in Washington by electric utility

What to know about the Washington numbers

• Rebates not checked yet. We haven't checked heat pump rebates in Washington yet, so the numbers here leave them out. Utility and state programs can take thousands off a heat pump, so ask your utility and your contractor what's available.
• Mostly average prices. Only 29% of Washington ZIP codes here are priced on a current utility tariff. The rest use the utility's average price from the U.S. Energy Information Administration, which is about two years old and doesn't show tiers, so the winter price of extra kWh is estimated. Enter the rate from a recent bill for a closer answer.
• Time-of-use rates. One utility's tariff here charge different prices by time of day. We assume heating and cooling use is spread evenly across the day, which can be off if most of yours falls in peak hours.
• Regional fuel prices. EIA doesn't publish a Washington price for every fuel: propane uses the national average and heating oil uses the national average. Enter your own price if you heat with it.
