in THE MAIN WALL
I am trying to figure out a way to radiant heat (staple up below floor) a small area (bathroom)that is part of a baseboard zone. I need to avoid additional pumps/mixing valves/ separate runs back to the boiler, etc. I was thinking about using momflow t's with a throttling valve, with or without a full size bypass with valve to control flow rate. Heatway tubing should handle the higher temps. but I'll use another product or softwall copper if prefered. The size of the tubing, spacing under the floor, and flow rate should be able to compensate for the higher water temps. (180-195 degrees). Any thoughts would be appreciated. Sam

    radiant zone in a zone

    We've done lots of these, Sam and I know of no easy (cheap) way to do it. We do close spaced tees in the loop piping and add a mixing valve and a small circ. You need a manifold to throttle the flow. Any other way would not give you the control or comfort level you seek. IF there is a better way, I'm all ears !!!!
