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 Baths 2 - 2.5 Baths 3 - 3.5 Baths
Number of Bedrooms 1 2 3 2 3 4 5 3 4 5
Number of Bedrooms 20 30 40 50 50 50 60 50 60 60

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.
