I have watched landlords switch the circuit breaker off to hot water heaters in empty apartments. I started doing the same thing on weekends.
When I left the building on Friday morning, I turned off the circuit breaker for the hot water heater. When I returned Sunday night, I switched it back on so I would have hot water on Monday morning.
I recommend shutting the electric power off to the water heater any time you will be gone for a full day or more. Keep in mind that electric water heaters do take time to heat up again.
Wrapping a water heater insulation blanket on your water heater tank is worth the cost and effort. If the water heater is out in the garage or in a utility shed, it definitely should have an extra blanket of insulation.
Strapping a blanket of fiberglass insulation around the hot water tank is an easy, do it yourself, project that will save you money. If the hot water heater is powered by natural gas, keep the blanket a foot off the floor to allow proper airflow to the gas burner.
If the hot water tank is located inside the living space, an extra blanket of insulation is good for two reasons. During the heating season heat that is lost from the water heater helps warm the living space. That is OK but it is not an efficient way to heat. During hot weather, heat wasted from the water heater tank adds to the air conditioning load.
Reducing your use of hot water will reduce your energy cost. Take short showers. Minimize the hot water used to wash dishes and clothes.
Insulation and water conservation are effective ways to keep more of your cash in your pocket.
