Plastic pipe on full installs

[ceedy]

In addition to my gibberings about my experience with plastic..

The Black plastic tubing I used in my first install all those years ago was only a single layer tubing no special multi layers, so no oxygen barrier , but then had no problems either.

Originally driven by a Parkray solid fuel, with no controls .. on windy days you could make horsehoes in it ! LOL. and later with a Thorn Housewarmer
( being replaced this month).

The First few metres of pipe was imperial size Copper to the Tank/pump etc..and the rest was brass manifolds ferrules plastic pipe etc.

Over the years the amount of debris/sludge that appeared in the system
has been negligable.

And for many years it ran on plain water with no additives.

Only when I recently changed the piping as mentioned before, I did a chemical flush and to be honest it wasn't worth the cost of the flushing agent, so little muck appeared.

I'm off 😱

Would that have been Acorn pipe ? We had awful trouble with that , water like oil !
Our water is soft , no limescale what is yours ?

All the new house builds & refurbs i go on all use plastic to carcass out htg & supplies, to alot of folk its the norm now.Plumbers also dont want bundles of copper tube lying around waiting to be nicked.Its all about costs these days & using plastic seems to be more cost effective.

single oxegen molecules are smaller than water molecules hence the barrier in heating grade plastic

plastic is easy to use/ bend just the joints are so bulky but in combination wth copper can save shedloads of time just remember those inserts or its niagra time

The pipe was from some company who also seemed to sell sunbeds.. LOL what a recomendation !, must have been going for a while as I added a rad quite a few years later and was still able to buy it from them .
the system came with brass dual pipe rad valves for 1 end entry by Danfoss.
Just can't remember the company name at the mo... ( still got a small reel of pipe in the loft somwhere..)
