  • The most effective method to determine the right size of tank is to consider if your existing tank meets your needs. If it does not (there are times when you run out of hot water) or if you do not have past experience to guide you, try to estimate your hot water needs.

    Hot water use varies depending on the number of people in your home and the types of appliances that are installed, as well as how your family uses them. Some types of appliances, such as large soaker tubs and whirlpool tubs require a lot of hot water when they are used, but they may be used only infrequently.

  • Typically this is due to the location of your water heater with respect to your shower. Often water heaters are installed in one end of the house, while bathrooms are located in the opposite end of the home. It takes time for the hot water to travel from your water heater, through your home’s plumbing before it reaches your shower.

    If you are involved with new construction, carefully consider the location of your water heater.

  • Utilities Kingston provides an installation allowance for water heater rentals.  

    Ask your installer up-front to provide you with any costs that might not be covered by the allowance. Additional costs may incur for the installation of the venting pipe and mixing valve.

  • In accordance with Ontario building code, when a water heater is replaced or installed, a mixing valve must also be installed. This required device controls water temperature, to protect occupants from scalding and is included in the price charged by the water heater installer you choose.  

    Utilities Kingston is committed to the prompt repair or replacement of the water heatershould it leak or fail.  

    About the maintenance or replacement of mixing valves:  

    • A mixing valve is a plumbing device, separate from the water heater. 

    • Maintenance and replacement of the mixing valve is not covered under our rental agreement. 

    • Utilities Kingston servicepersons are licensed gas technicians and may not work on or replace the mixing valve.  

    • It must be maintained and installed by a licensed plumber. Property owners must contact a licensed plumber to maintain or replace the mixing valve, at their cost 

    We pride ourselves on fast and reliable water heater service. When you call for service, it’s our priority to respond to calls within 24 hours. Our representative will ask you a few questions related to both your water heater and the separate mixing valve plumbing device. Providing accurate responses to these questions will help facilitate a timely repair.

  • Gas- and oil-fired water heaters require proper venting to safely remove combustion gases. Sidewall venting vents horizontally through an outside wall and may be either direct vent or power vent (fan-assisted).

    When we install a water heater, our certified installer ensures that the venting is safe and up to current building code. However, when it is time to replace your water heater, your venting may be updated to System 636 PVC flue gas venting, in accordance with provincial natural gas code.

  • Water heaters account for 17 per cent of the energy consumed in the average Canadian home. However, newer models of traditional water heaters have improved their energy efficiency by only about five per cent. There is little in the way of energy savings to be gained by switching to a newer model.

    There are, however, many effective free or inexpensive measures you can take to save on water heating energy consumption. To learn ways you can start saving today, check out the FAQ that follows.

  • There are many effective free or inexpensive measures you can take to save on water heating energy consumption.

    • Insulate water pipes.

  • A tankless water heater consists of either an electric element or a gas burner that heats flowing water and does not have a storage tank. 

    If you’re concerned about the heat dissipating from a traditional tank that stores hot water, consider that in Canada, during 6-8 months out of the year, this heat is dissipating into a space that you are trying to heat up anyways.

    Also consider: a tankless water heater uses more British thermal units (BTUs) than traditional tanks. If turned on and off frequently in a day, a tankless water heater can be more energy draining and costly than stored hot water tanks.
