What is the most flexible tubing out there for heating-radiant-on the market
also does anyone offer a quick connect fitting type to not lose fluid

Larry Weingarten

Hi, There has been rubber tubing, but it hasn’t held up well in the long term. PEX can flex more or less depending on size. I’m wondering what job do you have in mind? With that info, we probably can help you better. Fittings depend on the tubing, so can’t answer that question yet.

Yours, Larry

PERT tubing where not as popular is more flexible. Hydronic Alternatives has it. i think you can also get it from supplyhouse.com

REHAU has a RAUPEX SPEED radiant system here: https://www.rehau.com/us-en/raupex-speed

The A pex are more flexible, it has to do with the method of cross-linking. B pex is cross-linked after coiling and tends to want to stay in a coiled shape

Mr Pex has long advertised the most flexible pex.

PERT is an option but does not have the same ratings as pex.

I am not sure how I feel about radiant heat in igloos, they may lose some headroom over time.
Sounds like an interesting project.

Use the smallest diameter pex you can get; the smaller, the more flexible.

Know your math, flowrates and length. Then you can use the charts from the manufacturer to find head loss and therefore design the rest of the system.
