Insulating Your Water Heater
Wrap your water heater with an insulation blanket. It keeps heat inside and reduces energy use. Insulation also protects the heater from cold weather. Make sure the blanket fits well and does not cover vents or controls.
Flushing The Tank
Flush the water heater tank regularly. Sediment builds up inside and lowers heat efficiency. Drain the tank completely and refill it with fresh water. This keeps the heater working well and extends its life.
