Getting the most for your hot water needs


Hot water tanks provide hot water Besides furnaces and air conditioning, hot water tanks are the biggest energy consumer in your home consuming nearly 20% of your total household energy. In fact, according Natural Resources Canada, the average person uses 75L of hot water per day and the average Canadian household uses 225 L. Showers, faucets, clothes washers, dishwashers – all the hot water adds up, and so does the fuel!

Hot water tanks are the most common source of hot water heating in Canada for their simple design and efficient delivery of hot water. Hot water tanks store heated water in a tank available for use. When you call for hot water at a tap or showerhead, hot water flows from the tank and unheated water then flows into the tank to replace the hot water used. An electric element lights the burners with natural gas to heat the water and maintain water temperature as set on the tank itself.

All tanks are also equipped with a galvanic anode usually made of magnesium or aluminum alloys that protects the tank from rust and other mineral content that can corrode the tank from hard water.

 

What is an EF factor? What is a FHR rating?

The EF (Energy Factor) is the efficiency rating of gas fired hot water heaters. Mathematically, it is the amount of hot water energy divided by the total amount of energy used by the hot water tank over a 24-hour period. The EF accounts for standby losses when hot water is not being used and the operating efficiency of the tank when it is heating water. When comparing tanks, a higher EF indicates higher efficiency.

The FHR (First Hour Rating) measures how much hot water the tank can supply during the first hour starting with a full and heated tank. When considering your hot water needs this should match or exceed your households maximum estimated hot water use in your house in the first hour. The higher the FHR, the more hot water the tank can deliver during the peak use time. FHR is a better indicator than tank size of providing your family with the hot water it needs.
