Free Hot Water Analysis: |
(Number of gallons of hot water needed) * (8.34, the energy required to heat fluid 1 degree) * (Delta-T, the desired water temperature - the incoming water temperature) = (Daily Btu's required) / (SRCC collector daily Btu rating) = # of collectors |
5 units * 42 GPD = 210 * 8.34 * 65 = 113841/28,400 = 4 Collectors
Minimum Storage = 27.67 * 4 * 1.25 = 138.25 Gallons |
16 units * 42 GPD = 672 * 8.34 * 65 = 364291.2/28,400 = 12 Collectors
Minimum Storage = 27.67 * 12 = 332 Gallons |
52 units * 38 GPD = 1976 * 8.34 * 65 = 10224000/28,400 = 37.7 Collectors
Minimum Storage = 27.67 * 38 = 1051 Gallons |
