Ecotec PLus 825 & UFH

[Old Account]

I love working on them. So easy.

True! These are very easy to work on. A lot of space to be fair. These boilers are very heavy too:/

So you are saying I have to swap my pipes around? Are you saying the 2ay I have conntected it up is right? According to manufacturer yes. But why did the previous installers connect this the other way around?

So what would you just me to do?

will do if I meet home in person.

But what should I do now? Take the pump out from the ufh and let it run from the boiler pump only.

Could you give me an answer in what the way forward is?

whats the heat load of the ufh i would be surprised if its over 5kw thats really your issue can you down rate the heating on vaillints ?

Don’t know how much heat load it has got. But how comes that the pump at the Manifold works against the boiler pump? It does not make a sense at all to be fair. I do not think that the whole setup is correct the way it’s been done. The boiler pump pushes I to the top and the manifold pump pushes right back ...

You seemed like to have a solution to solve this problem. I could possibly take the manifold pump out and cap top and bottom end off and let the boiler do it’s job

after much looking your set up is a rehau manifold hkv-d with a
fixed temp control set

and it was piped up correctly

So, weird that there is written flow and return but pipework has to be fitted the other way around. But thanks a lot for your help shauni.

Yes you can mate

 

[markfxy]

the flow and return manifolds are marked correctly the flow from the boiler connects to the return manifold Uponor do it this way as well

Yes the ecotec plus heating load can be adjusted to as low as 3-4kw. D.ooo.
