Adsibob Posted November 30, 2022 Share Posted November 30, 2022 A number of members here recommend Wilo for quiet UFH operation. We have four pumps in our install, made by "Warmer". They are quite loud. The positions of these pumps means most of them are outside of a the bedrooms, but there are two in particular that can still be heard. One services three zones, total floor area of about 34m2. The other services 4 zones, total area of about 62m2 Which pump or pumps do I need? A quick search for Wilo pumps found a few different options: https://www.bes.co.uk/catalogsearch/result/index/?q=wilo Link to comment Share on other sites More sharing options...
JohnMo Posted November 30, 2022 Share Posted November 30, 2022 I have a couple of the central heating pumps, you just need to size them for your system. Also have a grundfos all are super quite. Is the noise the pump, or just the water moving through the system? Link to comment Share on other sites More sharing options...
Kelvin Posted November 30, 2022 Share Posted November 30, 2022 Most pumps are generally very quiet. I had a Grundfos pump start to whine which was a pre-cursor to it eventually failing. Most of the noise from our previous system was water flowing through the valves. Link to comment Share on other sites More sharing options...
jayc89 Posted November 30, 2022 Share Posted November 30, 2022 I have a Grundfos on our UFH (think it's a UPS3). It's running at speed 3 to provide the flow demand of all loops at the same time (single zone). There's a distinct humming noise when it's on, that can be heard ~ 3m away, separated by the under-stairs and a closed door. Link to comment Share on other sites More sharing options...
dpmiller Posted November 30, 2022 Share Posted November 30, 2022 Yep, we've three Yonos and they're *very* quiet. Standard length variant would be: https://www.bes.co.uk/wilo-yonos-pico-25-1-6-central-heating-pump-20460/ Link to comment Share on other sites More sharing options...

I couldn't see dimensions for the amount of space this would occupy. Our "warmer" pump has already been boxed into a cupboard and this one looks like it protrudes out much more than the one we have, which is this one: Link to comment Share on other sites More sharing options...
dpmiller Posted November 30, 2022 Share Posted November 30, 2022 you'd need about 11cm *in front of* the retaining nut Link to comment Share on other sites More sharing options...
