Piping for in-floor heat

Recommended Posts

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? Thanks, Ed

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?

There are numerous methods but this is the way I do it.

The foil back on the duct insulation reflects stray heat back to the floor. More insulation is installed underneath (not shown).

What you have there is an unknown.

Most of the piping is installed up against the subfloor with foil backed insulation below. Here is another picture of the sloppy manifold work

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.
