stainless steel flexi pipe instead of pex and copper

[steosman]

Has anyone used the flexible stainless steel pipe ( similar to gas track pipe) for new heating systems or general plumbing. I had a look at it today in suppliers and it looks good. Slightly more expensive than pex but cheaper than copper. Has all the strength of copper but flexibility of pex. I'm going to try it on the next heating system i do in a week.

Is the internal bore smooth?

What the 'f' is "pex"? I've heard of and seen 'trak' pipe........... Is this for gas or water?

Don't fix the floorboards down too tight!

Probably the same stuff you get for solar. Does it come pre insulated?

It's the same construction as solar pipe but the wall thickness is a few mm thinner. It's not a smooth bore which would worry me about sediment build up. I'm going to suggest it on my next heating system but have to talk to manufacturers technical department first. I don't think it comes pre insulated but i only had a quick look the last day in the suppliers. I'll try and post some pictures and any documentation i get.
