Size is important.
You don't want to constantly run out of hot water because your water heater is too small. Make sure you consider all the factors before making a decision. If you rent a natural gas water heater from Kitchener Utilities, you pay a rental fee based on the size and type of water heater. The rental charge is subject to increase by the City after the initial year. Billing periods shall be determined by the City and may be adjusted from time to time.
