EditSolar Water Heaters
Heating water with a solar water heater can save a
typical 4-person household approximately 2,700 kWh
or $325 per year if supplementing an electric water
heater, or $200 per year if supplementing a gas
water heater.
A solar water heater preheats cold municipal
water before it goes into a home’s water heater.
Generally, a solar water heating system can meet
50% of the hot water needs for a typical 4-person
household year-round. This is substantial,
considering heating water accounts for approximately
20 to 25% of a typical energy bill (and more for
electric heaters). Systems can produce 100% of needs
in the summer months and vary in production for
the winter months.
