Warmer UFH manifold and pump set

[Adsibob]

I had four manifold and pump sets manufactured by Warmer installed about 3 months ago. A couple of them have been running since just before Christmas to get the screed dry, the other two were only commissioned a few days ago. Of the two that were commissioned a few days ago, one has stopped working. So unless it's an installation issue, that is a 25% failure rate.

Hopefully it was just an installation issue that will be fixed when the plumber comes back to take a look, but I'm just wondering if anybody else has any experience with this brand.

Here is the product:

That looks just like the generic no name manifolds that I bought from ebay (for a lot less than that price).  In what way has it gone wrong?  Probably the pump failed?

 

I changed the pumps on mine as those cheap ones were noisy, I now have the little Wilo pumps on mine.

Is it Fairly straight forward to change the pumps? Of the four manifolds we have, only one is in a place where the noise might bother me, and that is the one that is being problematic. I will see what the plumber has to say, but good to know whether changing the pump is an easy job.

Yes standard fittings at each end of the pump.  If you want quiet, first choice is Wilo, second choice is Grundfoss.
