5 ways to save money with your water heater

Set the thermostat to 120 degrees

If your water heater lacks a thermostat, check the temperature by running an instant-read cooking thermometer under hot water at the kitchen sink. Electric water heaters have two thermostats – don’t forget to lower them both.

Insulate the pipes

Use pipe insulation or self-adhesive pipe-wrapping insulation tape to insulate the first 3 feet of pipes entering and leaving the water heater. Just don’t wrap the actual water heater – that could cause problems.

Turn it off when you leave town

No need to heat water when you aren’t at home for more than a few days. Some natural gas heaters even have “vacation” settings. Just don’t forget to turn it back on when you get home – it will take at least an hour to re-heat.

Conduct regular maintenance

Your manual will tell you how to keep your water heater happy.
