Jeremy Harris Posted April 27, 2019 Share Posted April 27, 2019 14 minutes ago, Simplysimon said: so should i go with grundfos or get a different pump? 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. 1 Link to comment Share on other sites More sharing options...
ProDave Posted April 27, 2019 Share Posted April 27, 2019 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? 1 Link to comment Share on other sites More sharing options...
joe90 Posted April 27, 2019 Share Posted April 27, 2019 Another one for a wilo pump ? Link to comment Share on other sites More sharing options...
jack Posted April 28, 2019 Share Posted April 28, 2019 We've had a Wilo running our UFH for three years, summer and winter. Hasn't missed a beat and is completely silent. Link to comment Share on other sites More sharing options...
