Use less hot water

Reducing hot water use is an easy, affordable way to see significant savings on energy and water bills. Ideas include:

  • Run automatic dishwasher only when full.
  • Wash and rinse full loads of laundry in cold water.
  • Install low-flow showerheads with thermostatic shut-off valves to turn water off when shower water is ready.
  • Check for and repair plumbing leaks.

Insulate hot water pipes

Insulating the hot water pipes in your home can save energy wasted through heat loss, and keep your hot water from cooling before reaching the tap. Wrap at least the first 6 feet of pipe coming from your water heater, or extend the insulation throughout your home piping system for more energy savings.
