Energy efficiency with electric water heating
Electric water heaters operate at up to 96% efficiency, with heat pump water heaters exceeding 200% efficiency. That means they waste almost no energy—or money. Compare that to to fossil fuel models that are 90% efficient at best .
There are several electric water heater options available:
- Grid-enabled water heaters
- Heat pump water heaters
- Residential storage tank water heaters
- Commercial storage tank water heaters
Tips for reducing your water heating costs
- Install low-flow showerheads and faucet aerators that will help you use less water.
- Insulate long runs of hot-water supply pipes, especially sections that pass through unheated spaces.
- Repair or replace leaky faucets. A faucet that leaks one drop per second wastes more than 2,300 gallons of hot water per year, which could cost as much as $36. The replacement washers needed to repair a leaky faucet cost only a few cents.
- Lower your water heater thermostat to 120° F. Or ask your plumber to raise the temperature and install a mixing valve to the line. A properly installed mixing valve on an 80-gallon water heater increases usable hot water to 120 gallons and adjusts the temperature to a lower (safe) level as it leaves the tank.
