I have a question that comes from my other life as a Mod over on Hearth.com, where we have a lot of folks that want to use their wood boilers to heat their hot tubs, as an alternative to feeding the Overpriced Electric Co...
In the hydronic world these days, people use a lot of PEX (Cross-linked Polyethylene) tubing - it is really good for heating systems, and for domestic water supply plumbing, with a lot of advantages and a few downsides.
One of them is that it lists a lot of chemical incompatibilities in some of the technical papers on it - including high levels of chlorine and various petrochemicals, and so forth.
It is OK with the chlorine levels found in tap water and such, but pools generally run a lot higher, plus people often use various oils and lotions that might be a problem (and not just for the guy trying to maintain the pool chemistry! )
I know I haven't seen any mention of using it for pool / hot tub plumbing - including just doing a search on PEX -
Does anyone (preferably w/ pool building background) have any definitive answers on whether or not PEX tubing is compatible with pool and hot tub chemistry?
