Hi all,
I'm currently in the thick of renovating my house and have my floorboards up. I'm looking to install some new radiators and notice that I have 8mm microbore, which I am keen to replace so that I won't have to worry about it in the future. The Flow & Return pipes are 15mm otherwise and the tee off to each rad is 8mm.
I would like to avoid having to cut a chase out for each downstairs radiator, but equally I know I dont have enough height above to drop in 2000mm copper pipe between the plasterboard & wall. Therefore my plan is to tee off from the F&R pipes using copper and put a 90 degree bend close to the wall, attach a compression fitting coupler and then run a length of plastic pipe down to the rad, attach another compression fitting coupler and finish it in copper with a 90 degree bend out to my right angle TRV valves. For my upstairs radiators, I won't need to use plastic and will do the job in copper 15mm.
I also plan to mark up my rads, attach the brackets and cut my lengths and do my bends the day before, so I can get the job done in a day. In light of the above, I would really appreciate some guidance on the following:
1) Does this sound like a reasonable approach?
2) Are there any issues with me replacing 8mm with 15mm piping? There will be 4 rads in the house where the pipes are not accessible and therefore will remain on 8mm microbore.
3) If I use plastic pipe in between the wall cavities, will it require sheathing/insulation or clipping? I would aim to clip at the top and close to the rad anyway (approximately 2.4m apart). The upstairs radiators will be fitted with copper piping throughout, as they are closer to the floor, but I am wondering if I will need to sheath/insulate and clip the pipes? I'm concerned about getting enough depth to attach clips around 15mm pipes.
4) For my plastic pipe, I was looking at using 'FloFit FPX15B/25 Push-Fit PE-X Barrier Pipe - White 15mm' from Screwfix and I would like to check if the inserts I need for the compression fittings are proprietary to each type of pipe manufacturer or can I use any 15mm pipe insert?
Thank you in advance
