How to lower the cost of running an electric water heater
Electric tank water heaters keep 40–80 gallons of water hot around the clock, switching their heating elements on whenever you use hot water or the tank cools down. The elements are typically 4,500W, and total run time for a family is roughly 2–4 hours a day, which is why water heating is often the second-biggest line on an all-electric home's bill. Heat pump water heaters do the same job with 2–3 times less electricity.
- Set the tank to 120°F (49°C) — many ship at 140°F, which wastes energy.
- Insulate the first few feet of hot water pipe and fix dripping hot taps.
- Consider a heat pump water heater when your tank needs replacing — they use about a third of the electricity.
