I had a local plumber come out to look at making all the connections (I hate plumbing, and can't justify buying the crimp tools to complete just one job.) He said he understood what I was wanting to do, but was going to have difficulty explaining it to his employees, so I said I would throw together a rudimentary drawing showing the flowpath. I told him that although it looks like a bunch of 90's in it, there really weren't, I was just trying to fit everything onto a page. Does this drawing appear to be an adequate representation? I am running both heat exchangers in series with individual isolation valves and by-passes around both heat exchangers, a thermostatic mixing valve on the outlet of the water heater and a boiler fill/make-up water line tying into the return to the boiler coming from the hot outlet of the plate heat exchanger. Am I missing anything important?

Very well done, don't forget temp gauges!

I did forget those! Thanks for the reminder!

Ok two quick dumb questions;
Pumps, don't you need a few of those, in the system?
In my experience, always put a Wye or sediment strainer in front of the FPHE (both sides, OWB and Domestic)
Other than than LOOKS good :thumbup, nice simple installation

Yes, the pump is at the owb, so it is not shown in the drawing. I plan to install a wye after the pump at the boiler, but I've never heard of putting one on the domestic side. Do you really catch much of anything with municipal water?

Depends on the source ::), at my parents old house I am not sure a wye strainer would have been enough!!! They were one of the first houses off the water tower (small town of 300) and about once a month they would have to clean out the little filter things on there sinks casue they would be almost plugged with stuff coming out of the water tower.
At my house, in Southern MN I do not have such an issue, so no strainer was required.
