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. 15 Model Selection Guide Appliances or fixtures in simultaneous use during peak demand Ground Water Temperature Zone Southern Zone Central Zone Northern Zone 1 305 or 505 305 or 505 305 or 505 2 305 or 505 305 or 505 305 or 505 3 505 or 705 (2) 505 or 705 (2) 505 4 (2) 505 (2) 505 (2) 505 5 (2) 505 (2) 705 (2) 705 6 or more Multi-system Multi-system Multi-system *Note: This Selection Guide is based on 120ºF outlet water temperature. 16 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.
