Hi Folks
So i am about halfway through my MVHR install, using 92mm semi rigid ducts from Hybalans. Does anyone know if the Ubbink ducting usually listed as 90mm is actually the same? The fiitings all look very similar, and I would have thought that there are not that many actual manufactures of the ducting. I purchased tow50m rolls and thought it would be enough, wrong! I need approx 40m more, and the Ubbink stuff is circa £160.00 per 50m roll, versus the HB+ at circa 275.00 so quite a saving.
Anyone any tips on using EPP 180mm dia ducst for the initial input and exhaust from the unit/
Thanks
Andy
