DescriptionWrap your water heater in an insulated blanket to retain the heat inside.. This reduces the amount of energy needed to maintain the water temperature while it is sitting in the tank, for example during the day while no one is home, or in the night when no hot water are being used.
- hot water
- year round
Assumptions We Madeestimated savings for insulating water heater ranges from 25% - 45% depending on existing insulative properties of the water heater unit. Assume the low end of savings and energy requirements for a high temperature (140 degree) water heater. Used gas heater model to determine total annual standby heating requirements (not for heating consumed water). http://www.eere.energy.gov/consumer/your_home/water_heating/index.cfm/mytopic=13070
