2. HEATING WATER IS THE MOST ENERGY INTENISVE SUBSTANCE ON THE PLANET MORE THAN IRON, URAINUM AND TUNGSTE, EXCEPT FOR LIQUID AMMONIA. IRONIC THAT 99 PERCENT OF THE POPULATION USES HOT WATER DAILY. 2

3. IT TAKES 37 TIMES MORE ENERGY TO HEAT 1000 GALLONS OF WATER THAN IT DOES TO MOVE 1000 GALLONS FROM A WATERSHED TO A HOME AND ON TO A SEWAGE TREATMENT PLANT 3

4. Energy Consumption At 31%, Water Heating is the 2nd largest energy user in a typical home and a critical consideration for sustainable design. US Dept. of Energy’s Lawrence Berkeley National Laboratory

5. Distribution Q: What is a hot water distribution system and how does it consume water or energy? A: A hot water distribution system is the means of moving hot water from the point at which it is heated to the desired fixture, whether it be a faucet, shower, or other location where hot water is needed. *An inefficient design leads to water waste while waiting to get hot water, and energy waste by rapidly losing heat which needs to be made up by the water heater.

12. AVERAGE DAILY DEMAND OF HOT WATER IS 12 TO 15 TIMES PER DAY. THIS WOULD AVERAGE BETWEEN 7,000 TO 10,000 GALLONS A YEAR AND 80 TO 140 HOURS A YEAR WAITING FOR HOT WATER TO ARRIVE. 12

24. US Potential Annual waste in existing homes (10 gallons/day): 415 billion gallons (1,276,125 AF) 3 billion therms 50 billion kWh $10 billion Annual increase in waste in new construction: 1,200,000 new units per year Increased waste: 4.4 billion gallons (13,443 AF) $110 million In 20 years waste will grow to: 88 billion gallons (270,000 AF) 20 % of current waste Additional water and energy waste in multifamily, commercial and industrial buildings.

25. LOOK AT ONLY 100,000 HOMES THE WATER LOSS LOOKS LIKE THIS BASED ON 7,200 GALLONS LOSS PER HOME PER YEAR; 730 MILLIONS OF GALLONS OF WATER /YEAR 25

46. A Grass Roots Effort Will you help me help communities? Plus, you will most likely be surprised at what you learn! Water: we generally take it for granted; it’s fundamental for life!. Hot water: waste it and it’s a double-whammy – we waste energy too! Most citizens in the United States know many locales have water issues. Daily, newspapers report about water concerns. Is it safe to drink? Is there enough? How expensive is it? Are we headed toward restrictions or rationing? How about water for farming? How about the impact on your wallet? Did you know the average home spends around 20 percent of the annual energy bill just heating hot water? Do you know yours? How much of your energy bill is going “down the drain?” Are you willing to gather data on the water and time you waste while waiting for hot water in your home? It will take you about 10 minutes, total. This is a great project for children. You will probably be surprised at the results. Why this grass roots effort? The national data file will be used to develop local, practical solutions to help communities and homeowners (like you) and your locale by reducing wasted water, energy, time and money. It's a win-win for everybody!

47. Email your results to me (see below) and here is what I will do with your information: 1. I will provide you an accurate - but conservative - estimate of how many gallons of water (and hours of your time) you waste each year waiting for hot water. 2. Your results (without any identifying information) will be included in a data file of like data being collected from all over the USA. Thank you. Dave Grieshop; Sierra Vista, AZ Also, you may randomly win a $25 Starbucks gift card!

48. Collecting wasted time and wasted water data, while waiting for hot water, in your home; no pump. First, I thank you for helping me build a data base of information! The entire time involved is less than 10 minutes over 2 days. What you will need: a watch with a second hand (a cell phone works great); a measuring cup; and a small 2-3 quart kitchen pot. (The key is to make sure no one has used any hot water anywhere in the home for at least one hour; two is better.) Day 1 at the kitchen sink: 2 separate non related events. Turn on the HOT water only and start your clock. You will note two different times in seconds. The first time is when you feel the water temperature begin to change (start to get warm) and the second time is when the water is hot enough that you would now take a shower. Record the two times observed. Warm; secHot; sec Now place the small pot under the faucet. Turn on the COLD water only for 15 seconds. Measure how many cups of water you collected and record to nearest 1/4 cup. Water, cups Day 2 at a master bathroom fixture. 2 separate non related events. Turn on the HOT water only and start your clock. You will note two different times in seconds. The first time is when you feel the water temperature begin to change (start to get warm) and the second time is when the water is hot enough that you would now take a shower. Record the two times observed. Warm; secHot; sec Now place the small pot under the faucet. Turn on the COLD water only for 15 seconds. Measure how many cups of water you collected and record to nearest 1/4 cup. Water, cups

49. Finally, please answer these questions about your home: What is your ZIP code? Is your home one-story or two-stories? Approximately what year was your home built? Is your water heater storage or tankless? Approximately how many square feet is your home? Is your water heater in the garage? Yes or no? Thank you!
