Sizing
Model Selection Guide
• To properly size On-Demand units for a home, two factors are of
critical importance . . .
1. Incoming ground water temperature
- Will determine the amount of “temperature rise” required to
achieve the desired hot water outlet temperature (120ºF is
recommended)
2. Peak hot water demand
- How much hot water the home will need during its busiest usage
period
13
Ground Water Temperature Factor
14
Peak Hot Water Demand
• Consider all the applications and fixtures in the home that use hot
water, including lavatory faucets, kitchen faucets, washing
machines, dishwashers, showers and bathtubs.
• Determine how many of these appliances and fixtures will be in use
at the same time during the busiest usage period.
– For example, if one kitchen faucet, one shower and a washing
machine are all in use during the busiest period, use the number
3 to make your selection from the Model Selection Guide.

Energy Star® Qualified Models
Tax Credit
High efficiency water heaters are not just environmentally sound–over the course of their life-cycles,
they can also help homeowners save a lot of money. Due to a recent extension of residential tax
credits for energy-efficient improvements, several of our American On-Demand models are now
eligible for a tax credit of up to 30% (with a cap of $1,500) of the purchase and install price.
