Water Heater
You can lower your water usage and bill by using minimum water heater settings
GRU recommends a setting of 120 degrees for domestic hot water heaters. If dishwashers have pre-heaters or boosters, you may be able to reduce tank settings from 140-150 degrees to 120 degrees. Hot water to bathrooms may be disconnected or turned off at the lavatories, since most customers do not require available hot water for hand washing. Using minimum water heater settings reduces the energy demand of the tank and excessive heat given off by the water heater. Following these tips will help you save water and money:
- Consider an insulation jacket for older model hot water heaters
- Look for the yellow "Energy Guide" label when purchasing a new hot water heater
- Insulate exposed copper hot water pipes with foam pipe insulation
- Replace rusty and corroded pipes
- Do not turn water heater off and on unless you will be gone for at least two days
