Water Heater Replacement. Traditional storage water heaters have an expected lifespan of between 10 and 12 years. In contrast, heat pump water heaters are typically cited as lasting between 13-15 years. When considering a heat pump water heater, we recommend that you proactively plan to replace your existing water heater.

Selection Criteria. When selecting a replacement water heater for your home, consider the following: Fuel type, availability and cost. The fuel type or energy source you use for water heating will not only affect the water heater''s annual operation costs but also its size and energy efficiency. See below for more on selecting fuel types.
