13. Sizing

14. 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

15. Ground Water Temperature Factor 14

16. 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
