I have been looking around the net for a couple of months and started building my own wood boiler. I have got most of the bases covered about size, water capacity, etc. I have some questions about the plumbing side of the whole system. I have 6 loops installed in my workshop which is 32x48. I bought the manifolds with the small pex valves pre-installed from Menards. I have an ITT bell and gossett circ pump for the system. I hope to run my boiler at 160 to 180 degrees. I understand that I should only put 100 degree water into my slab. How should I plumb my pump and mixing valve into my open (non-pressure) system? Can I pull water through the mixing valve? This would be the easiest way for me to put the pump on the boiler and push water through the whole floor system. The pump would only see the 100 degree water. I have looked everywhere for a simple plumbing diagram to no avail.. Any suggestions would be appreciated. Thanks, Brian
