@PeterW So!, green crosses approx location of roof vents (1.5m or slightly more apart) Red box MVHR unit mounted internally on wall. This seem good? Distance from in/out vents to MVHR will be short. I was thinking (oh no!) before I wall mount it if I should say do OSB , then thick rubber ( to reduce noise) then unit onto that.

Yeah . But it makes sense for me to put half the panels on either side . Vent placement probably not going to effect PV position - just trying not to shoot myself in the foot later . Will put a photo up later of where I intend vents to go

Hey @joth that would just be too easy ! My unit is about 35cm deep ; so you need at least 70cm to get the filters out . Pita in the limited loft space ( if possible at all ) . Dream in a bedroom for access !

Problem is I don’t want to scupper where PV panels will go at a later date .

Yeah - bad access will plague my unit if loft space positioned . I was trying to do 1 loft hatch for mvhr and header tank . Just not do able in any sensible way . Bedroom it is ! . Makes the install 10 times simpler !

Do the roof vents have to go high up on the roof ? All photos I’ve seen put them near the ridge . Can they be lower ? . If units in bedroom shortest run is to vents lower on roof

I also asked without installing the unit ; just stuck a plug on it and listened . Said it would be a good test as the unit will be noisier than usual due to factory defaults and air movement. Will try that next week !

Right ! Spoke to vent axia . They said unclean filters can increase noise ( guess the fan works harder ) ; so if filter access is easy more likely to clean filters . A ‘sound proof’ cupboard wasn’t an unreasonable suggestion apparently. We have our main bedroom and a secondary bedroom ( primarily for me when I apparently snore ) . Anyone guess which room the units going in !!!

Ffs ! . On the floor in a bedroom in a ‘sound proof’ box !?!?!?!? ??

Ok , ok ! What about in loft space but above a bedroom ? - anyone able to comment on noise from unit ??

Anyone got a vent axia in say a bedroom ? ( perhaps in a wardrobe ) - and perhaps sound proofed it ???? - not desperate or anything !!!

Erm ! Funny how much bigger it is when it arrives ! . No idea how to get this through a loft hatch and positioned so that filters etc can be altered . The roof trusses get in the way completely- snookered !!

Kodi ....

Jesus ! That woke me up !!!

What lovely finger nails !

Z wave all the way ! . I prefer wired switches though - back to a din rail of fibaro/quibino switches . Then just wireless z wave to control them .

Bloody spell check !

So the qubino make an audible click ? ; even DIN rail version ? - what about fibaro equivalents??

Will test cable mode later !!

Yep - it’s very nice . I can see i’m going to use it rather a lot ! Surprised how large it is!

I’ll wait for mine to explode ?

????

Build underground! It’s a dream !! ??

Best to have it all prepared before the pour ! . No adding afterwards !!!!!

Looking at the drawing ( unless I’m missing something) why not some mesh in the trench ? . Stronger and something for the L bars to tie too. This is what I had
