That's simply poor design. Claiming that microbore is superior because an idiot can't install it inappropiately is a strange way to justify it....mind you..in your case...

Well, we surmised it might be scale, because: no evidence of sludging, and only affected a couple of rads, then predominantly one rad, and eventually shutting off ALL rads bar that one seemed to shift whatever it was.
It's suspected that a bit of scale broke off from within the boiler (it was rather prone to kettling for a while) which is what then lodged somewhere in the system. Can easily see how a flake of scale would end up attempting to fit down a microbore pipe having come out the boiler on rather thicker piping, and plug it enough to prevent flow to a rad or two, depending on where it ended up.
There were no indications of anything else going on, no leaking overflows, no hot feed tanks, rads were (when they actually all heated up) hot at top and bottom, no sign of sludge coming out when system drained and flushed, etc.
I still can't see a lump of scale managing to block the bigger bore pipework (that's effectively about what goes in/out of the boiler) like it could block microbore.

That level of scale/sludge would block up a small bore or microbore system. As Andy has pointed out, micro has nothing whatsoever to do with the blockage, and condemning a system fitted by the millions, because of one poorly designed/installation/maintenance is quite foolish.

That's why IMM has a microbore sewage system. In pipe diameter, size doesn't matter, and he is in a permanent state of verbal diarrhoea, he flushes out his sludge frequently.
Gawd. Anyone who can't see that a small bore system isn't more prone to blockage needs his arteries examining..

depending on use, water, maintenance, etc, anything from 10-28 years.

Its useless to argue with IMM. Unless you are prepared to print a glossy brochure and send it to him with a manufacturers name on it, he won't believe anything you say no matter how reasonable.

Ah, like the one you used to justify using microbore to replace a poorly designed small bore system.

What a relief. Instred of IMM's veiled allusions a complete rational description.
To which my comment is 'true, but probably irrelevant'
UF heating is done this way anyway mostly - well mine is, and yes, it is amenable to all that stuff, but it gets a bit irritating to implement.
The one thing I did enjoy tho, was being able to balance all the zones
*at the manifold* using the tiddly little flow meters on each branch.

Alas you used Polyplumb, not recommended by Gledhill. The only plastic pipe maker I know that holds this distinction by any other maker.

, and condemning a system fitted by the millions, because of one
So of copurse condemiong all small bores systems because of one poorly designed/installation/maintenance (example) is of course completely correct.

Go to the Polyplumb web site.

They have a an "overlay floor heating system". It is insulation layed over an existing floor with dedicated grooves for the piping. Quite thin too. You can download the info or send for it.
