Moonshine Posted June 23, 2022 Share Posted June 23, 2022 Has anyone installed a manifold in a studwork wall cavity before with an access hatch. I am using 89mm studwork which gives a decent space and also the location i am thinking i could make this cavity a bit bigger. My main worry is making the access panel looking o.k in a plasterboard wall, though it would be behind a door that would mainly be open. Thoughts?

Moonshine Posted June 23, 2022 Author Share Posted June 23, 2022 It would be a 6 port manifold Link to comment Share on other sites More sharing options...

I have the oppotunity to make the cavity deeper, this pump looks 125mm if i made the cavity 140mm could i fit the manifold and pump in? Link to comment Share on other sites More sharing options...

I am using 89mm studwork As Peter suggests this doesn't really make sense practically. The manifold might only be 50cm wide but you've got the pump return on the LH side so you are going to have to cut out at least one stud vertical which will then need cross bracing top and bottom and the bottom bracing will then impede the UFH out and return runs. Have you got 60 or 40cm stud centres? If 40 then getting it in is going to be problematical. OK if you really want to lose your UFH out and return runs within the studwork, then you may be able to notch back the CLS uprights to 40mm and brace/support the two cutouts sections lengths of CLS at 90°. That would allow you set back the manifold and pump 50mm or so and allow the UFH pipework to run cleanly within studwork, but then so you will still need to box out the manifold and pump area with a shallow cover maybe 80-100mm deep. Even so, this is all very tight and for very little gain IMO. Also heaven help you if you need to do any maintenance !! Link to comment Share on other sites More sharing options...
ProDave Posted June 23, 2022 Share Posted June 23, 2022 I fitted one of mine in a void made for it about 160mm deep. To achieve that I rotated the pump for least protrusion forwards. Link to comment Share on other sites More sharing options...
MikeSharp01 Posted June 23, 2022 Share Posted June 23, 2022 I would take care mounting a pump on / near thinned out studs as vibration / transmission of the hum may be an issue. Link to comment Share on other sites More sharing options...

Kelvin Posted July 25, 2022 Share Posted July 25, 2022 In the last house I created a deeper void on the stud wall and used the top of the void as a shelf with a nice bit of oak I picked up for free. We had two manifolds but the other one was in the downstairs loo and I did the same in there again creating a shelf. I couldn’t make it all fit in our stud walls.

Trw144 Posted July 26, 2022 Share Posted July 26, 2022 (edited) All my kit was supplied by Giacomini. I'll see if I can find the specific details of the cabinet (I don't have a pump in the cabinet as I have a seperate electronic mixer/pump unit). edit . 110mm or 150mm versions available Edited July 26, 2022 by Trw144 Link to comment Share on other sites More sharing options...

One oncern i have is thst the cabinet will be in a corner of the livingroom and i am concerned pump noise will be a disturbance Edit, found the 150mm version which will be best for me https://www.giacomini.com/en/products/r557i Edited July 26, 2022 by Moonshine Link to comment Share on other sites More sharing options...
Kelvin Posted July 26, 2022 Share Posted July 26, 2022 They are generally quiet when running but not silent. I doubt you’d hear it above the TV. You could also acoustically treat panel Link to comment Share on other sites More sharing options...
TerryE Posted July 27, 2022 Share Posted July 27, 2022 (edited) The main source of sound is the pump circulation, and this depends on the flow rate that you need to dump the heating to the slab. You can either work this out using math, or by trial and error. In general you want the flow to be as low as you can get away with, as this will generate the least noise. In my passive house I only have three loops covering the entire ground floor slab and I can get way with the pump on the lowest setting. Our manifold is in a cupboard in the ground floor toilet, and I can just about hear it when sitting on the can. 🤣 Edited July 27, 2022 by TerryE Link to comment Share on other sites More sharing options...
Nickfromwales Posted July 27, 2022 Share Posted July 27, 2022 Why not mount the pump at the source of the 22mm flow and return pipes instead of in the wall? It’ll be virtually silent then. Link to comment Share on other sites More sharing options...

Ufh manifold in the cabinet in stud wall i living room behind a door that is going to mainly be open and 22mm pipes going out to a remote pump mounted on the opposide of the wall behind / in a cut out of the back of a kitchen cupboard for maintainance It also means that the cabinet in the wall can be smaller.

Adsibob Posted July 27, 2022 Share Posted July 27, 2022 Is the Location of your manifold already fixed? If not, consider moving it elsewhere, maybe on the other side of that same stud wall, and hiding it with a self made MDF cupboard like this: Link to comment Share on other sites More sharing options...
