Hello All,
I am looking for the right recirculation system for my home.
1. I will provide 1/2" return lines to kitchen and two remote bathroom groups, each with a tee to the hot water supply for each location (all currently homerunned) and with a check valve at each end point.
2. I plan to tee all three 1/2" return lines lines into a single 3/4" line at the boiler
3. I plan to have the recirculator connected to the 3/4" return, which will connect to the cold water supply to indirect tank.
4. I plan to install buttons at all three locations, which call for the recirc pump to activate.
The advantages of this arrangement is using only one pump, and having recirculation on command from point of use. There is an inefficiency in that it will heat hot water in all three lines, when only one is may be needed, however, it won't run on a timer, heating the lines when not needed at all.
Requirements:
1. 3/4" connections
2. ability to call from remote button (three button inputs - not sure if I connect all three to one set of contacts on the pump - probably yes, just completes circuit and sends a call)
3. bonus feature - the system knows when the water in the line is already hot, to avoid running the pump needlessly
There are a lot of products out there. I do believe that some that are intended for under cabinet install could be installed at the boiler. Also, many that are intended to use the cold water could be connected to a dedicated return instead - I think... After looking at many products, I am unsure what is best for my application. Any advise is appreciated.
