What Pennsylvania Residents Should Know
Electricity in Pennsylvania averages $0.168 per kWh — near the national average. For a typical three-person household, heating water with a standard electric resistance tank costs roughly $513 per year, while a heat pump water heater doing the same job draws about a third of the electricity, costing around $135. That gap, roughly $378 every year, is what pays off the higher upfront price.
Against natural gas the math is closer but still favorable in Pennsylvania: at $1.30 per therm, a standard gas tank costs roughly $201 per year for the same household, versus about $135 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 Pennsylvania 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.
The federal 25C credit for heat pump water heaters ended December 31, 2025, and Pennsylvania does not currently offer dedicated state-level programs — but many utilities still provide water heater rebates of $300–$1,500, so check with yours before buying. Even at full price, replacing an electric resistance tank typically pays back within 4–8 years of a 10–15 year lifespan.
