I’m trying to do this but just with a compression adaptor for 32mm to 40mm as my trap is further downstream.
i have bought a floplast adapter but it won’t tighten enough onto the 28mm copper pipe. Any specific brands you would recommend that are flexible enough?
Looking to order a UVC soon from Telford for my ASHP setup. Does anyone know when you would use the hi-flow variant versus the normal one?

I was looking at this recently too. If you need to put copper in between then another adapter it adds a lot to the cost. Might as well buy the Hep2o official ones.
Have also been looking at these then buy an adaptor for the size you need.

anyone else tried these or see a problem?
nice they also do red and blue ones!
not sure either of those are certified for airtightness. Probably would work but not been tested for it.
For most tapes you need to use a primer on parge coat as it tends not to stick well. There are some exceptions that can go direct but they tend to be more expensive.
I have been using a combo of me315 or PHS Modbau Internal Airtight Window Tape depending on whether I need it plasterable or not. Works out at ~£20 for 25m
interesting, I have a similar setup. It’s not a great thermal bridge! What is your cavity filled with?
mine is with mineral wool and at the moment you can see it between the steels. I don’t see what the benefit of adding PIR is here
Did you end up doing this?
I'm at a similar point and trying to decide if it's worth putting acoustic insulation in the attic floor joists. The attic will just be used for storage and MVHR, but maybe the insulation will prevent noise being transferred between bedrooms on the first floor over the walls?
Although my preference would be for in-roof panels and it doesn’t seem as though all the GSE landscape modules only work with panels that are max 1120mm in height. Yet all the panels I can find are 1134mm.
Does seem a minefield getting everything to fit together!
