What Michigan Residents Should Know
Electricity in Michigan averages $0.184 per kWh — above the national average. For a typical three-person household, heating water with a standard electric resistance tank costs roughly $562 per year, while a heat pump water heater doing the same job draws about a third of the electricity, costing around $148. That gap, roughly $414 every year, is what pays off the higher upfront price.
Against natural gas the math is closer but still favorable in Michigan: at $1.05 per therm, a standard gas tank costs roughly $162 per year for the same household, versus about $148 for a heat pump water heater. Whether the difference justifies switching depends on installation cost and how long you plan to stay — run the calculator above with your actual numbers.
One practical note for Michigan homeowners: heat pump water heaters need roughly 700–1,000 cubic feet of surrounding air and run best in a garage, basement, or utility room that stays above about 40°F, since they pull heat from the air around them. With a typical 10–15 year lifespan, the annual savings above usually repay the higher purchase price well within the unit's service life.
With the federal 25C credit having ended December 31, 2025, state and utility programs are now the main incentives — Michigan residents can access up to $1,200 through state heat pump programs, and many utilities offer their own water heater rebates of $300–$1,500. Heat pump water heaters typically install for $2,500–$4,000, so these rebates meaningfully shorten the payback period.
