It is time for Project #owf17, time to get ride of the freezing floor tiles, I am installing radiant heat under the flooring from the basement, hopefully removed the insulation was the worst part, I was thinking I could just come off the supply manifold with some kind of thermostatic valve that would keep the floor at a certain temp, then have the other end of the line feed into my return manifold I was gonna stick with the one pump outside which I will be changing from a 007, the local plumbing shop did not have the valve is there another name for it? Does my setup seem ok?
