  1. .....I thought to myself, as I instructed my man to cut the excess tail off a coil of Wunda UFH pipe. He cut some more, the noise got much worse. What’s going on ?!? We hadn’t hooked it up yet so a leak was impossible.......and then I twigged. The good folk at Wunda now sell the coils of UFH pipe pressurised with compressed air, and when I say pressurised, I mean pressurised. If you cut straight through you’d better be holding both pieces as it’s like stabbing a car tire ( probably ). They must have it close to 6 or more bar guessing by just how much air came out of a 100m coil. I then noticed the pipe ends. They’ve basically got plastic plugs glued / crimped into each end to keep the pressure up and keep any crud out, and I assume this pre-pressurising benefits in a couple of ways. Wunda know the pipe is sound at dispatch, you know it’s sound when you get it, and if dopy gits with long screws or multi tools inadvertently damage the pipe after installation / floors down etc there will be an undeniable “whoosh” of compressed air to let them know. Can’t help thinking that would also be of benefit during Ufh at the slab stage too as the pipe is likely to be a bit less susceptible to compression perhaps. Folly, or first class. ?
  2. As usual, things are turning a bit last minute. Manifold is now on, loops are on etc. I have started to bleed my 12 circuits and am finding that there is a lot of air being dispelled in the bucket (had to empty about 6 buckets on one loop already). As concrete is being poured tomorrow first thing I'm feeling a bit anxious. Have had to rig up a temporary water supply to the manifold from an outside temporary tap involving a longish hose pipe and there are a few drips along the way to the manifold supply valve (i.e. at the outside tap etc). Is it possible that the air is being introduced into the ufh set up, rather than within the ufh pipework/manifold? No sign of leaks in pipework yet. I won't have a pressure reading until I have water in all circuits so can't yet determine if there is a pressure fall. Certainly no leaks in the ufh pipework (had a visual check in the rooms done so far). I'm hoping the air is being introduced elsewhere - could that be the case? Does it matter that I may have some air in ufh pipework when the concrete gets poured? I presume as long as it is all under pressure then I should be okay? The air can be expelled at some other distant point I presume. Hoping @Nickfromwales or some other experts can advise! TIA!
