if it was me, id run it all in 32mm from the meter. For a little increase in cost the flow losses are as small as you can make them.

Hi, I am looking to fit a Vent Axia sentinel multivent into a relatives bungalow. I have access to ceilings for all the rooms (5) that need venting. https://www.vent-axia.com/range/lo-carbon-sentinel-multivent-plus Does anyone have experience of these units ? Are they any good? Should I be looking at another brand ? What sort of ducting is best to use, flexible/rigid ? thanks Dave
