Building a toxic free home, plastic piping on central heatin

Odd question, here goes ….trying to limit any toxins in my new build. From insulation to paint choice...flooring.
My questions relates to underfloor heating, the plastic pipe that is used is pex piping, logically thinking the pipe heats up. Does Plastic piping tend to release air bourne toxins when heated up. I hear warm water or drinking water ran through pex piping has been tested and contains toxins. Now worried about the materials used in underfloor heating pipes.
Thanks All

I’m all for protecting the environment but this is really an odd question - what about the 1000s of metres of piping before it gets to you?
Can't help but agree. You are going to spend a lot of time & energy controlling something you just can't control. Not unless you have your own water purification system, green power generation system, crop system and live 1000 years ago before humans starting pumping everything we can into the atmosphere.newbie29 said:

Edit; FWIW, in a previous life I worked in a company that created ultra ultra ultra ultra pure water (stuff that makes bottled water look like slime...). It was for military, medical, science etc.... All that was pumped round the machines in (specialist) John guest pipes & fittings! All plastic..

Copper is toxic in high enough doses, it's one reason you shouldn't drink from the hot water supply, the higher heat and lower mineral contents tends to leech more copper from the piping...
I thought it was traditionally down to the fact that old cold water storage tanks in the loft were not covered and there was a possibility of dead things floating around in it, plus the chance of bacteria being present from standing water.Hence the reason why hot water storage should be kept at 60 degrees plus to kill of the majority of bacteria that may be present.
Incidentally, I thought the idea of domestic hot water being at 60C, or a bit higher, was more to do with it being hot enough for cleaning purposes, but not hot enough to scald us. I didn't know about the bacteria aspect, but as we don't drink it, is that so important? I dunno, just asking.

It's primarily a precaution against legionella bacteria.frisbee said:

Copper isn't that safe.
its been used for at least a hundred years, it is as safe as they come, in the context of the ops question.Edited by Six Figs on Saturday 3rd February 14:18
