The mower had other ideas. 1/4 of the way through the blade snapped in half. The post mortem reveals it has been cracked for some time (it has encountered a few obstructions / stones etc many times) Awaiting a new blade to continue.
July 30, 20197 yr Author 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 !!
July 30, 20197 yr Author Anyone got a vent axia in say a bedroom ? ( perhaps in a wardrobe ) - and perhaps sound proofed it ???? - not desperate or anything !!! Edited July 30, 20197 yr by pocster
July 30, 20197 yr Author Ok , ok ! What about in loft space but above a bedroom ? - anyone able to comment on noise from unit ??
July 30, 20197 yr Author 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 !!!
July 30, 20197 yr Ours is in a cupboard in our pantry. You can't hear it unless it's on boost (which is rare - we tend to leave it on the background setting). I don't know how loud the Vent-Axia is though.
July 30, 20197 yr Author 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 !
July 30, 20197 yr Ours (Kingspan / Mitsubishi) is in the plant room next to our bedroom, with just a door (FD30) between the plant room and the bedroom. Even with the door open, you cannot hear the mvhr at normal speed, and when you put it on boost, for a shower, more noise comes from the ceiling vent than directly from the mvhr unit. I wired a house a few years back where they wedged an mvhr in the loft, it was really tight access, and they created 2 loft hatches so you could crawl in from both ends to change the 2 filters, but I have a suspicion it was going to be such an awkward miserable job that it might not get done as often as would be desirable.
July 30, 20197 yr Author 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
July 30, 20197 yr Vents are better on the roof plane rather than the ridge. Ridge vents are more for exhaust from gas and soil stacks where you want to create a negative pressure to draw the air from the vent.

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 !
July 30, 20197 yr This does make me wonder: do any units have filter access from below? Positioning it with its own loft access hatch directly underneath it would be pretty convenient in our install: just stand on steps, open a ceiling hatch and reach up to access the filters.

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

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 !

July 30, 20197 yr Author 1 hour ago, PeterW said: Roof has 2 sides ...??? 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 Edited July 30, 20197 yr by pocster
July 30, 20197 yr Author @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.
July 30, 20197 yr @pocster are you single storey? We are and our MVHR vents come out of the wall not the roof.

August 21, 20197 yr That's the model I'm thinking of using. Following with interest! Condensate-drain arrangement ready?
