Formule
## Water Heater Sizing **Daily Demand = Occupants x Gallons per Person** **BTU/hr = Demand x 8.33 x Temp Rise / Recovery Hours** The constant 8.33 is the weight of one gallon of water in pounds. Tank size is rounded up to the nearest standard 10-gallon increment.
Exemple Résolu
A household of 4 using 20 gallons each, 70 degF rise, 1-hour recovery.
- 01Daily demand = 4 x 20 = 80 gal
- 02Tank size = round up to 80 gal
- 03BTU = 80 x 8.33 x 70 / 1 = 46,648 BTU/hr
