Hello group.. I have seen a few of these advertised, and was wondering if they really work..They claim to save you a bunch of water which is wasted by waiting for the hot water to arrive to the faucet..My desired use is for the laundry..The laundry room is quite a distance from the water heater, and being a water efficient front load washer, it uses very little water and on a hot water wash, by the time the washer fills, the water is just getting hot which then makes the washer heat its own water making a very long cycle..If these things really work, this would be a life saver as I could program the water circulator pump to come on when I do laundry usually...Here is an example of this system:
Thanks so much everyone!!! John
