When I install my new system this summer I would like it to look like this if it will work. It is very similar to Nofossils "simplest pres. storage design" but with an additional zone added for my sunroom.
My plan is to use the Grundfos Alpha to run the 3 zone valved zones ( 2 baseboards and the DHW) and have a seperate pump on the sunroom in-floor radiant. The propane back-up boiler would only come on if the sytem water temp fell below 145F.
I have not included the usual stuff like safety pop-offs, auto fill valve, air seperators and shut-offs in the drawing for simplicity.
Take a look please and let me know what ya think.
thx, Pat
