We have both, a Grundfos on the UFH manifold and a Wilo on the DHW preheat heat exchanger.  Both are reasonably quiet, but the Wilo is a fair bit quieter than the Grundfos.

Another +1 to Wilo.My cheap manifolds from ebay came with IBO pumps that were dire. Both now changed for Wilo which are incredably quiet.  

 

Grundfos are also good, but it might be worth asking if there is a Wilo option?

Another one for a  wilo pump ?

We've had a Wilo running our UFH for three years, summer and winter. Hasn't missed a beat and is completely silent.
