mridgeelk Posted November 24, 2009 Report Share Posted November 24, 2009 This is the first time I have seen this piping. It is marked for snowmelting and for in-floor heating. I thought my pictures would be clear enough to identify the manufacturer and type, not so. Anybody familiar with it? Also this is the first time I have seen the manifold piping installed in this manner in an unconditioned area, the crawlspace. Any opinions about this installation?

Mark P Posted November 25, 2009 Report Share Posted November 25, 2009 The black tubing looks a bit like "ONYX" by Watts, great stuff, but the install looks like a real mess. Radiant floor heating is a very exact science and every job is enginered to the specifications of the house. This looks like someone did not know what they were doing. I mean how is the heat supposed to radiate through the insulation? Quote Link to comment Share on other sites More sharing options...
kurt Posted November 25, 2009 Report Share Posted November 25, 2009 It looks like the Heatway with oxygen barrier, or maybe Onyx. Here's a pic of some Heatway I saw last week. I can't really tell anything from what's visible, other than the manifold is a messy tangle.

mridgeelk Posted November 25, 2009 Author Report Share Posted November 25, 2009 Most of the piping is installed up against the subfloor with foil backed insulation below. Here is another picture of the sloppy manifold work Click to Enlarge 42.55 KB. I will recommend that a qualified heating contractor evaluate a way to straighten this mess out including insulating the exposed piping. Thanks for all the information.
