Water Heater Frequently Asked Questions

Does Union Gas rent or sell water heaters?

No, Union Gas does not sell, rent, or service gas appliances.

Should I wait for an older water heater to breakdown or replace it sooner?

An older water heater can be less energy efficient than a new unit. Contact your rental company or a contractor to have a water heater evaluation completed.

Why do I need an anti-scald valve?

The building code has been amended to specify that new or replacement water heaters supply a maximum hot water temperature of 49 degrees Celsius (120 degrees Fahrenheit). Check with your local building department for the requirements for your home.

What are the water heaters I've seen in the bathroom near the shower? Do we have these in Canada?

You may have seen tankless water heaters that supply hot water on demand instead of storing it in a tank. They may be placed close to where the hot water is needed. In Canada, they are usually located in utility rooms or the basement. Learn more about tankless water heaters.

What size storage tank do I need?

A TSSA-qualified contractor who installs water heaters or a retailer will help you make the right choice in tank size.
