    CAPACITY

    It's important to select a hot water heater that provides enough hot water for your home. An undersized water heater will work harder and have a shorter lifespan.

    Storage Tank

    Determine the proper capacity for your household based on the number of bathrooms and bedrooms in your home. If you choose to purchase a unit with a tank, consult the table below for help in determining storage capacity.

    Determine Water Heater Capacity
    Number of Bathrooms 1 - 1.5 2 - 2.5 3 - 3.5
    Number of Bedrooms 1 2 3 2 3 4 5 3 4 5
    Minimum Tank Size 20 30 40 50 50 50 60 50 60 60

    Tankless

    This unit heats water directly without the use of a storage tank. To determine the size of the tankless water heater you would need, you must calculate how much hot water you need to use at one time. Routine behaviours, such as running the dishwasher while taking a shower, can exhaust a smaller tankless unit. It is best to understand the demands and expectations you have for your tankless water heater before you purchase.

    DIMENSIONS

    Once you know the capacity for your water heater, remember to take the unit's dimensions into consideration.

    • The unit should have ½" clearance on the sides, 12" on the front and 18" off the floor.
    • For closets and close quarters: A new conventional storage replacement unit may be larger than the old one because more insulation is required to meet the latest strict federal energy standards.
    • When upgrading to a larger unit: You may need to have plumbing run to it if it has to be relocated. One way to avoid relocating the unit is to select a model in a non-standard size, such as a unit that is shorter but larger around, known as a "low boy" hot water heater.
    • When purchasing a tankless water heater: Ensure the location you choose for installation meets the unit's ventilation requirements. Does it require an exterior wall near a gas supply line, water supply line and/or an electrical power source? Placing your tankless heater near the correct supply lines and power sources can be the easiest and most cost-effective way to run the venting.

    Energy efficiency

    Energy Star Eco Options Whichever fuel source you use, a water heater can be the third largest energy user in your home, so select the system that ensures your needs are met without wasting energy.

    Quick Tips

    • Know the measurements of the area where the unit will go to be sure it will fit in that space
    • You may need a venting kit if you're going to install a gas unit
    • Setting your hot water heater to 60°C/140°F is usually hot enough for most needs
    • Flush your water heater at least once per year to remove sediment

    Additional Features to Consider

    Self Cleaning

    • Automatically fights lime and sediment buildup
    • Lengthens tank life
    • Extends peak efficiency

    Recovery Speed

    • Important if you use a lot of hot water
    • The quicker the recovery speed, the less time it takes to heat a full tank of water

    Automatic Shutoff Valve

    • For fire-prevention measures
    • Shuts off the flow of gas if there's movement in the ground or the gas flow experiences a sudden, sizeable increase
