Central heating with 10mm plastic pipes

Copper is very thin nowadays as well ,not like the old copper we take out.
I would say the plastic will last longer than the copper

That is a very valid point. Some of the copper pipe these days is remarkably thin. I actally tried installing a self cutting tap into a piece of copper pipe and instead of it cutting through the pipe it crushed it- the water went everywhere

as long as it's got the kite mark on it, it will all be the same if you are looking at the same grade of tube

I'm looking to install central heating into a house built in 1899. I'm happy to take up floorboards and understand the design of central heating, however I am unsure what type of pipe to use. I'm not a plumber!

The first option is to use 15mm and 22mm copper piping with soldered joints, insulating the whole way, I thought this was the most reliable but it appears some people have problems with it. I presume it would take longer to solder all the joints and worried about leaks, damage from leaks, and the wasted time of draining system down for testing etc.

Would anyone advise using plastic joints with copper pipe?

The other plastic options appear to be:-
Hep20
Speedfit
Polypipe
Uponor
Does anyone know if there is a cost benefit for using plastic piping? And is there any real difference between the types of plastic piping and joints?

And give any recommendation, would be much appreciated!!

You need to start a new thread for this one.
Its great that you feel confident to try doing your own plumbing but don't take on too much or it may cost you more in the long run.
There are lots of pit falls in using pushfit fittings and copper, sharp edges cutting rubber O rings being one of them if you aren't careful.

Our copper pipes laid in concrete with no protective sleeve started to leak after approx 30 years, once from a joint, once from corroded pipe.

A plumber joined plastic to copper when we fixed the first leak, we concreted over, then laid an expensive wooded floor. Three months later it started leaking again. We discovered it was where the plastic was joined to the copper.

So my advice is this. NEVER join plastic to copper where it is inaccesable. We'll be using plastic to avoid joints under the concrete and connect plastic straight to the rads. I can't see how that would look DIY myself (see post above).
