  1. I’ve just spent most of last week installing the distribution boxes, ducting and plenums on my BPC/Vent Axia system. I thought it would be worthwhile sharing some pictures, It went well and was relatively easy to do. I tried to keep ducting passing over each other in the joists to a minimum but it was unavoidable in some places. Having two ducts on top of each other in a web joist was a bit tight and didn’t leave a lot of room for insulation. I had already installed the 150mm PVC pipe through the roof and drilled a 150mm hole for the second PVC pipe through the wall. I then mounted the Vent Axia unit on the wall and figured out where to mount the distribution boxes in the metal web joists between the ground and first floors. We have vaulted ceilings upstairs so it seemed easiest to mount the boxes here rather than up high in the first floor. Here’s my rough in of the MVHR unit. Ignore the angles of the pipes. These will be straightened up on the final fix. Here are the distribution boxes. Required careful planning and it didn’t seem to matter where they were because of the metal web joists there was always at least one duct which was a tight squeeze through the joists. I have a change in levels between the main part of the house and the lower level which causes a bit of head scratching as to how the get the ducts from one section to another. This was exacerbated by the fact that there was a steel running across the lower level which I had to navigate around. I built a dummy stud wall in the lower level and ran the ducts behind this. I need to get 3 extract and 2 supply ducts into the lower level. Here’s a photo after the first 4 ducts were run. A bit of boxing in required to hide them, but relatively easy solution. and here’s what it looks like in the lower level. And finally, a ceiling mounted and wall mounted plenum. I quite enjoyed doing it and it was satisfying to see it all done.
  2. Fitting my vent terminals for my Mvhr supply and extract valves and I know a few on here have used BPC for the ducting etc. When cutting the plenums down to size, the bit that sticks through the plasterboard that the ceiling valve pushes into, have people left them to protrude a little bit lower than the plasterboard? It is just when I looked at how the valve attaches to the plastic tube it needs to compress a foam gasket and I assume for this to work properly it would need the tube to be left longer than the flat surface of the p/board to make a snug fit? TIA
  3. My vent axis mvhr has a small remote control display panel supplied with a 4pin connector the only place I can see to connect it to the main mvhr unit is a socket marked BMS. Is that the correct connection? Thanks
