If you have a PEX 1/2 line with a home run installation...worst case wait for hot water would be less than 30 secs (about a gallon - 1/4¢) I believe there might be a temperature sensor sensor that shuts the pump off when the hot water "arrives". (unless I have this product mixed up with another "point of use" hot to cold transfer system) Coupled with a timer & a "permanent on" "hot wire" job this unit might fit the bill..... but all in all, a lot of work to save a few ¢'s worth of water everyday in the kitchen. cheers Bob |

I'm as "green" as the next guy but I'm more concerned with saving aggravation than saving water. So if we go the recirculate route then I think it's going to have to be an automatic unit. The Laing unit you linked me to last week turned up "unavailable" besides being pricier than I expected, but otherwise looked good. But now I'm wondering: The water heater is in the laundry room, adjoining the kitchen, maybe six or seven feet from the kitchen sink. Maybe I can bypass the attic PEX manifold and just "hot plumb" the sink to the water heater. |

I'm surprised that it takes 2 minutes to get hot water in your kitchen. If the manifold (home run design?) is in the attic & the water heater is laundry room ...how much tube length is there to clear of hot water? If the run is 1/2 PEX & were only 50' ...that's about 1/2 gallon of water. A direct line to the kitchen sink would give you hot water fastest, that is, short of a installing a recirc loop. cheers Bob |
