  1. Hi all, I can't be the first person to have a fight with leftover 75mm flexible pipe (32m), and trying to re-roll it fairly tight. Any pro tips? I don't have access to a large cable drum, but thought about using an offcut of 8x2, and attaching a couple of 2x1s to the ends to form a sort of cable drum. Would welcome any easier solutions though! Cheers Tim
  2. The blue Domus seems to be the same spec as the red Airflex, and £30 cheaper. The other ones nothing much is mentioned.
  3. I have the same unit, and did find it to be a little noisy! I installed the same ducting kit from BPC and no complaints. I added a silencer on the extract side too, and since then it's very quiet in the house. Since I did mine, they seem to have cheaper 75mm pipes - mine are all red, but green and blue are cheaper, and I cannot really see why!
  4. For my bathroom i just rely on the MHRV units built in humidistat. For the kitchen, I got a clever relay with a wide input voltage and a timer, and connected it into the wiring for the extractor fan motor. So the system boosts when the extractor comes on, and remains boosting for 30 minutes after.
  5. I would ask what professional qualifications he is looking for. The answer will probably be 'there aren't any', in which case re-submit your results!
  6. Stranded?! You're not using jacks and panels then!?
  7. Hope you chose a nice colour! Just the 1 roll?!
  8. My BPC manifolds were totally un-insulated. I fitted them to a board on the ceiling beams, and then rolled the additional 200mm loft insulation over them. Pipes from them to the main unit are in the process of being insulated with 50mm rockwool
  9. I used Excel cat6 cable, was about £90 a box I think. No issues at all. If you then have someone 'qualified' punch it down to an Excel panel and mods, they warrant it for 25 years.
  10. I found cable basket was way way cheaper than tray, despite being just as good. £5 for 3m I recall, for a 50x55mm one
  11. I don't know really, there is the required 10mm under the doors. The room has a supply valve, so heat isn't likely to be sent into the room from the rest f the house when the door is closed?
  12. Sorry for the terribly slow reply.... family life happened and nothing else got done! Since starting this thread we no longer have pets in the house, and so the bedroom door now remains open when we are home (Someone is here most days). This seems to have cured the issues during the recent cold spell, so the issue seems to have been that the room just inadequately heated - it has a 800w panel heater that's always on and is set to keep the room at about 18 degrees. Last year, before the MHRV was fitted, we did run a dehumidifier for 2 hours each morning and that kept things mostly under control, except for the corners. Thanks for all the replies, much appreciated. Tim
  13. That's what I did on mine too... inserted a connector to the solid pipe and taped, then attached the flexi with a worm drive clip, then taped over that too. I used the fabric flexi's though, and there was no way at all they were going to go over the pipes any other way.
  14. I only had a silencer on the supply, but fairly quickly added one to the extract as well. The rooms with extract you can tolerate more noise, but it was still noticeable. £25 later and the entire system is almost silent even on boost.
  15. That's a lotta reading!! I will have a look properly tomorrow. I'd like to think my system is well installed - I took a lot of time over it, as it was to be for my own benefit / enjoyment. As you have probably seen elsewhere I had considerable issues with the balancing but I think that's resolved now, I'll be re-measuring everything this week sometime to confirm.
