Efficient water heaters use far less energy to heat water than traditional water heaters. Water heating is the second largest energy expense in your home. Efficient water heaters include:
- Electric heat pump water heaters: usually located in a garage or basement, and use half the electricity of storage electric water heaters.
- Tankless gas water heaters: provide water only when needed. Rather than store water in a tank, water is heated quickly as it moves through a heating unit.
- Storage water heaters: heat water in a tank using natural gas or other fuel, and have better insulation and improved heating efficiency.
- Wastewater heat recovery: also known as drain-water heat recovery systems, these water heaters capture the heat from water going down the drain to help heat fresh water coming in to the bath or shower.
You can also use renewable energy to heat water in your home, using a solar water heating system.
Federal, local, or utility programs may offer incentives for installing certain energy-efficient devices in your home.
