Water heating in your home accounts for about 13% of the total energy used. Replacing an older, inefficient hot water heater with a new high efficiency model can save up to $300 a year on your utility bills. Energy efficient models include:
- Solar water heaters.
- Heat pump water heaters.
- Tankless water heaters, such as those from Rinnai.
- High efficiency tank water heaters.
Tankless water heaters save energy, and money. According to the U.S. Department of Energy, operating costs could be up to 50% lower since there is no re-heating of water as with traditional water heaters.
