Steve, Reuben & Richard: Last week I received a call from the owner of a mult-head shower drawing 15 gpm of 105F water. He lives in North Carolina and his 40 gallon electric tank-type water heater ran out of hot water in a few minutes. I gave him my advice, install a tankless water heater with a 50%-DHR system to halve the load by recycling heat wasted down-the-drain. Solar is not an option.  
   What would your advice have been?

Terminology:A navy shower = turn on to wet skin; turn off to soap; turn on to rinse.A hollywood shower = turn on full blast; start singing; soap; turn off a the end.

A thermostatic value + volume control is  way better than a navy shower button because you can adjust the volume down to a level just to keep you warm while soaping.  This may convince more people to actually use less water while showering than the pure "Navy shower" approach.   The downside is thermostatic valves and volume controls setups are expensive.
