Hello,
We've just purchased a new home that has an Onix radiant floor living room installed between the joists from below. I've read the manual on installation and I have a few questions I'm hoping someone can help answer.
First, we neither have, nor does the manual say anything about installation of the metal fins that hold Pex or other tubing for other types of radiant floors. I'm curious to know if such a thing is made or Onix tubing and if it's something that can be done. It simply seems to me that with so little surface area between the tubing and the subfloor that the heat transfer is marked inefficient.
Second, the thermometer of the mixing valve for the radiant floor zone is set to 180 degrees. This seems high to me. I gather that considerable calculation goes into determining the heating loads for a space, the BTU's deliverable by the furnace, the flow of the water and the house itself. But I didn't see any direct guidance regarding this temperature and wondered what advice you might offer. The floor is hardwood oak.
Thanks in advance,
Val
