Join PSE Flex water heaters
Saving energy doesn't have to be a challenge. You can take simple steps every day to manage your home's energy use. This month, we are focusing on water heating. Your water heater is the second largest electricity user in your home, after heating and cooling. By joining the Flex program, you can earn rewards by letting PSE adjust your water heater’s energy use when the community’s demand for electricity rises, a process known as demand response. Read more about Flex water heaters here and check out our energy saving tips below.
- Set the water heater thermostat to 120°F or the "low" setting.
- Find and fix leaks in fixtures and pipes. If your water heater is leaking, replace it.
- Install inexpensive pipe insulation on all exposed hot water pipes and on the first three feet of exposed cold water pipe connected to the water heater.
- Wash clothes in cold water and take shorter showers.
- Use the dishwasher rather than hand-washing dishes and don't pre-rinse dishes.
- Install low-flow, high-performance showerheads and faucet aerators.
- Buy a water heater blanket, and wrap it around the tank to prevent heat loss.
