Other things to consider
- ? If someone is running out of hot water in the household it could be due to items such as oversized or jetted tubs, using multiple consecutive showers or several large loads of laundry. A larger capacity water heater should be considered.
- ? Gas units: Check to make sure exhaust vent will handle a larger water heater with more BTU input.
- ? If a family is planning to stay in their home for a long period of time, models made with a longer warranty should be considered. It's less expensive when installation and maintenance expenses are considered.
- ? Electric units: If the water heater has hard water that leaves deposits on fixtures and requires frequent replacement of heating elements, self-cleaning models should be considered.
