Conventional storage tank water heaters are the most common type of water heater in Canada.
They hold 76 to 380 litres (20 to 100 gallons) of hot water. They readily provide hot water to your home by using a tank to store heated water. As hot water is consumed, cool water replaces it and is heated by electricity, gas or oil. Older hot water heating systems typically consume more energy than their modern, efficient counterparts.
Since water is constantly heated in the tank, energy can be wasted even when a hot water tap isn’t running. This is called standby heat loss. Today’s energy-efficient models feature extra insulation, which reduces heat loss through the tank walls. Upgrading to an energy efficient storage tank water heater can improve your water heater’s efficiency.
