Title: insulation
Post by: tickman on December 21, 2012, 04:00:55 PM

I am installing a heat exchanger in my air handler in my attic. How much and what type of insulation should I use on the pex tubing. I can't decide whether to use the refrigeration type or closed cell they sell at Lowes.

You mean just on the tubing inside the home?  I would just use that frost king stuff from the hardware stores.

If heat loss is a real factor you could use 1 inch to cover the pex then cover that with say 2 or 2 1/2 inch.  Tape it good or if possible slide it on from the end while doing the installation. Of course pex you can take apart easily and slide on.  My pex is all in basement and I left open under kitchen floor to take the chill of the floor overhead.  Refrigeration has higher r value but is it worth it?   Good luck.
