Here is a great class to take at WaterEC 2010. Water Heating, Hot Water Distribution, and Water Conservation by Gary Klein, Gary's enthusiasm for every thing related to hot water is infectious.
Purpose
If our purpose is to create buildings that conserve water, then it is important to properly choose the water heater, and perhaps more importantly, install a water-efficient hot-water distribution system. The most water-conserving hot-water system would be one in which hot water would come out of the tap as soon as we turn it on. To provide instantaneous hot water, we need a water heater that starts out with hot water, and either a very short distance between the water heater and each fixture or appliance, or a hot water distribution system structured to provide hot water shortly after the tap is turned on. The hot water distribution system will be with the building for much, if not all of its life, so it is important to have it structured properly, both when it is built and so that it will still be water-efficient as hot water outlet flow rates and fill volumes change over its lifetime.
This session will explore the relationship among the components of high-performance water-heating systems by laying out the plumbing for a typical building on the floor of the classroom. The hot water locations will be drawn out to full scale using painter’s tape to draw the building. Then, tape of different widths, representing pipe of different diameters will be used to “pipe” the building. The efficiency of different hot water distribution systems will be evaluated in terms of water, energy, and time.
Learning Objectives
1. Describe how the choice of water heater affects water conservation. Tank and tankless water heaters, both gas and electric will be compared, as will hybrids and solar water heating
2. Explore how the way a hot water distribution system is structured determines the waste of water, energy, and time
3. Discuss the implications of how changing hot water outlet flow rates will impact the ability to conserve water over time with primary emphasis on showerheads and faucets
4. Consider how to incorporate these issues into programs and codes

Gary has been intimately involved in energy efficiency and renewable energy since 1973. One-fourth of his career was spent in the Kingdom of Lesotho, the rest in the United States. He has a passion for hot water: getting into it, getting out of it, and efficiently delivering it to meet customers needs. Recently completing 19 years with the California Energy Commission, his new firm, Affiliated International Management LLC, provides consulting on sustainability through its international team of affiliates. Gary received a BA from Cornell University in 1975 with an Independent Major in Technology and Society with an emphasis on energy conservation and renewable energy.
WaterEC 2010 will be held April 27, 2010 at the Marriott Nashville Airport Hotel in Nashville, TN. Early Bird Registration is open for all of our full-day courses.
