I remember that there was some chatter about hot water circulator pump activated by motion sensor. Lost my notes from previous discussion. Does anyone have email address on vendors/manufacturer of such systems? Thanks in advance.

What is better a hot water pump or tankless heaters?
Joe
Joe,
Are you thinking of putting a tankless unit in closer to your faucets?Others will know more about that, but you are looking at a much larger expense than an inexpensive pump to pull the "cold" water from the hot water line and "push it back into the cold water line, until the water reaches the desired temp.
I have the 2 bath and kitchen all on corners of the house and I was planning on a pump but I didn't know if tankless might be better. I know a pump is a must though!
My plumber is recommending a 5 gallon 110v electric heater on the hot water line as close as possible to the fixture(s). He says it's cheap to run 'cause you're never really heating cold water, just maintaining the temp of the small tank. Circulating pumps can get suprisingly expensive to run. Also, you're probably aware that in many instances, an experienced plumber can set you up a 'passive' recirculating loop.BTW, how many feet of 3/4" copper pipe holds a gallon of water? I need this to figure if a 5 gal tank will run out before the main hot water arrives. The pipe run is around 60 feet.ThanksBill

3/4 " copper.... do they still use that for plumbing? seems copper is the "new gold"
with a basic motion detector that will power up your pump and a run/start timer... you can make your pump only run for say... 2-3 min... and it won't allow it to kick back on for say an hour and then only if there is motion...
