Which to pick in Vermont?

  • Cheapest to run: Heat pump water heater at $494/year.
  • Heat pump water heaters use about 4× less electricity than a resistance tank for the same hot water.
  • If you don’t have gas service, HPWH is almost always the cost winner over resistance, with payback in 3–6 years vs a $1,500–$3,000 install cost premium.
  • If you have gas already, the savings vs gas depend on your local gas price — in Vermont the difference is $131/year in HPWH’s favor.

How we calculated this

Assumes a household using 24 MMBtu of hot water per year — a typical 2–4 person U.S. household. Energy needed = useful heat ÷ energy factor (EF). For gas (EF 0.62), 1 therm of fuel delivers 62,000 BTU of hot water; for electric resistance (EF 0.93), 1 kWh delivers 3,173 BTU; for HPWH (UEF 3.5), 1 kWh delivers about 11,940 BTU thanks to the heat-pump effect.
