Electric water heaters are an efficient way to heat the water in your home. With several options available, it’s easy to find one to meet your needs.
keep your water hot
​The most common type of water heater, storage water heaters, keep water hot and ready for use. Capacity ranges from 20 to 80 gallons and fuel options include electric, gas and propane. One drawback is the energy required to keep the water hot at all times. Using better insulated tanks or wrapping old tanks with insulation can help minimize standby energy losses.
heat pump water heaters
Heat pump water heaters transfer energy from the surrounding air to heat water in a storage tank. They are much more efficient than standard storage tank water heaters, especially in warm desert climates.
solar water heaters
Solar water heaters harness the sun’s energy to reduce water heating costs by up to 80%. They require backup by a conventional storage tank water heater to ensure that hot water is available when solar energy isn’t.
hot water usage
A typical household spends about $300 each year on electric water heating. Heating water accounts for about 90% of the energy needed to run a washing machine and 80% of the energy to run a dishwasher. Reduce your water heating bill by up to 50% by practicing simple cost-effective measures.
water heating tips
  • hot water uses a lot of energy - wash with cold or warm water instead
  • adjust the load setting on your washing machine for smaller loads to save water
  • installing low-flow showerheads can save a family of 4 up to 15,000 gallons of water per year
  • a water heater insulation jacket can reduce your water heater’s energy use by 10% - 12%, but check the owner’s manual first - some manufacturers don’t recommend using wraps
no tank needed​
Water circulates through a large coil and is heated on demand. Tankless systems can save energy associated with standby losses. But, depending on the type of system installed, they can result in higher overall energy use.
instantaneous recirculating tankless systems
A small pump continuously circulates water in a loop so that hot water is always available. This system provides instant hot water at any tap. However, the cost of recirculating hot water can result in the highest overall cost of any hot water system.
demand recirculating tankless system
This system is similar to the instantaneous tankless system, but only circulates hot water when the user activates a button. A small pump operates on-demand to provide nearly instantaneous hot water at any fixture. This system efficiently provides quick and convenient hot water because hot water only circulates on-demand.
