EcoRenovator - View Single Post - Pre-heating shower / sink water

I fitted both of our bathrooms, which are a 40' pipe run from the water heater with switched circulation pumps. What I did was to place a pump and electric valve between the hot and cold pipes. A temperature switch on the hot pipe. To make the water hot, you push a button to latch a relay that opens the control valve and starts the pump, as well as turns on a little red light. When the hot water pipe reaches 100 degrees, the temp switch unlatches the relay, shuts the whole mess off and you have hot water. I also have one under the kitchen sink, because the way the house is plumbed the hot water has to go to the north end of the house and back to get there, approx. 60'.

The electric valve in line is to stop thermosiphoning on a continuing basis. The system was made from available items and not too costly to implement.
