Emmeti manifold to new radiators.

[Dobbslc]

Hi I'm I've just joined and hope to gain some well needed knowledge! I'm replacing the old 1 pipe heating system in my house as its very old and full of leaks! We're putting down a solid wood floor so I don't want any joints under it that might fail!
I'm thinking of using the Emmeti manifold system for wall hung radiators but can't decide what pipe to use. I could use their own Gerpex pipe but its 16mm and I don't think it'll connect to "standard" rad valves or can I use 15mm pex pipe? Their tech guy that I spoke to said it had to be 15mm with a 1.7mm wall thickness, what 15mm pipe can I use?
Thanks!

will connect to standard rad valves but will need adapters eg

Nut & Insert Adaptor 16x15mm

Make your own manifolds 28mm pipe and fittings and use 15mm copper kuterlux pipe to the rads all joins above ground sorted. Kop

Whatever brand of manifold you use, use their pipe and fittings.
That way there should be no shortfall if an issue arises.
All pipe manufacturers will have fittings to connect onto radiator valves.
You don't want to be in a situation where you have a leak and the manufacturer states that their fittings are tested on their pipe, not anyone elses.
It would be very hard to prove the leak is from the fitting or the 'other branded' pipe

I have had no problem using Emmetti manifolds, their 10mm compression fittings and JG Speedfit 10mm pipe.
Next time, I might try a different pipe which can bend to a tighter radius....but it was bloody cold when the pipe runs were being pulled...

Also, i really like the 'point to point' style manifold heating compared to what is usually fitted in the UK.

Thanks guys, oz plumber & jerry would you think Emmeti make a trv that will take a Wiser / Nest / Hive smart thermostat?

Not sure what you mean.

Emmetti make a few different types of manifold. The T1 manifold just distributes the water and the T2 allows you to control the water.

So a T1 would be good with a single thermostat to control the entire system I.e 1 zone

The T2 can be controlled by actuators and you could therefore make each loop a zone. Great for multi-zone.

I have used the T1 to control a single floors in large houses with each floor have a single thermostat.

I have used the T2 to control the temperature in each room independently with (full) smart home controls.

I hope this helps.

I was thinking of using the T1 with smart thermostatic rad valves from Wiser/Drayton.

That should work

I've priced it all up and while not cheap it's not much more than copper pipes and much cheaper than using 15mm coils of copper!
My only worry is the PEX AL PEX Pope isn't really rodent proof! Any ideas on protecting it?
Thanks for all the replies by the way, helping the enemy (sparks)
