An electric water heater uses electrical energy to heat water for residential or commercial use. Instead of burning fuel, electric models rely on one or more heating elements inside the tank to warm water. They are often easier to install, do not require venting, and are available in tank and tankless formats. Choosing the right size, efficiency level, and electricity rate considerations are key to long-term cost and performance.

Electric water heaters pair well with solar or renewable power, making them a cleaner hot water option as grids get greener.
Are electric water heaters cheaper to install than gas?
Often yes, since they do not require venting or gas piping, but electrical upgrades may be needed.
Do electric water heaters cost more to run?
It depends on local electricity rates. Higher rates can increase operating costs compared to gas.
Can I add a timer to an electric water heater?
Yes. Timers can cut standby losses if hot water use follows a predictable schedule.
