(only the GRU table listed their number based on a 10 min. shower at 2.5 gal./min)<br /> *Shaving: 2 gal.<br /> *Washing Hands and Face: 2.6 gal.<br /> *Shampooing Hair: 4 gal.<br /> *Hand Dishwashing: 3.6 gal. (seems low)<br /> *Clothes Washing: 25 gal. (only GRU listed usage for various washer settings, note that this number does not corrolate to the model information)<br /> *Food Preparation: 5 gal. (DOE listings)<br /> <br /> By using these estimates we figured that we use the following amount of hot water each week:<br /> <br /> *42 showers per week<br /> *12 shaves per week <br /> *100 hand and face washings<br /> *7 dish doings per week (one per day but figure 7.2 gallons as there are more occupants than what the above average assumes)<br /> *5 food prep <br /> *6 loads of laundry <br /> <br /> The average daily usage is therefore: 192 gallons of hot water<br /> *per person: 28 gallons of hot water per day<br /> <br /> Note: The above estimates are made assuming 7 residents, which is the average annual number of occupants.</div>
