Hot Water Heater

I bet your hot water heater has this dial too. It not only regulates the temperature of the water as you use it daily, but it can go on vacation too.
Why heat water all week long while you are in Maui. Or Des Moines, wherever vacation takes you. Set your water heater to a lower temperature or “vacation” while you are on vacation and save some cash. It’s the green thing to do.
