Pocster Posted April 30, 2020 Author Share Posted April 30, 2020 Sorting out those awkward angled ceiling bits . Not much fun . They are at approximately the same angle now !! OSB’d them for extra strength . Link to comment Share on other sites More sharing options...
Pocster Posted May 1, 2020 Author Share Posted May 1, 2020 Don’t like these ceiling edges . Ceiling plasterboard would sit on nothing - shove some timber in there . Also assume I need to put noggins in the ceiling at 300mm apart for plasterboard. Link to comment Share on other sites More sharing options...
Mr Punter Posted May 1, 2020 Share Posted May 1, 2020 What centres are the trusses on? They look more than 600mm, but maybe that is a trick of your 'special' camera. If 600ctrs you can just use 15mm plasterboard. Link to comment Share on other sites More sharing options...

Might still do a noggin every 300mm across them all for peace of mind . Link to comment Share on other sites More sharing options...

You will obs need some more timber where the wall on the left is flush with the truss. 1 Link to comment Share on other sites More sharing options...

Pocster Posted May 5, 2020 Author Share Posted May 5, 2020 Noggins in bathroom ceiling . More tile backer board . Socket enteries for heated towel rails ( not a socket a cable faced plate ) 1 Link to comment Share on other sites More sharing options...
Pocster Posted May 7, 2020 Author Share Posted May 7, 2020 Noggins in the ensuite ceiling - yeah I know there’s too many ! . Think I’ll move that mvhr vent - to near the door ... Link to comment Share on other sites More sharing options...

Jeremy Harris Posted May 7, 2020 Share Posted May 7, 2020 Definitely best right over the shower, for two reasons. Firstly, that's where most of the humid, warm air will come from, so it makes sense to remove it as closely as possible from where it originates, in order to minimise the spread of humid air around the bathroom, where it may well condense out on surfaces. Secondly, showers are often towards the end of a bathroom and it's always much better to place both extract and fresh air supply ducts as far away from doors as possible, and never in the centre of a room, as being as far away from the door as practical allows the longest diffusion path across the room and so minimises any spots that might hold "dead" air. 1 Link to comment Share on other sites More sharing options...

Mr Punter Posted May 7, 2020 Share Posted May 7, 2020 I would want the unit to run flat out if I was having a shower. I would have thought that having it nearer the source would eliminate it more effectively, like having a kitchen extractor above the hob. Also, the vent pipes in the house would have a fair through flow of air and I would think that the internal surface of the ducting should be well above dew point. I wonder if there is any proper science behind this? @Jeremy Harris surely cannot be wrong! Link to comment Share on other sites More sharing options...

I’m struggling to move the vent as a zillion other pipes and cables in the way !! Ffs !! Shows they just don't understand the basic physics involved. As @Mr Punter rightly says, the ducts will almost certainly be above dew point, and anyway, as soon as the MVHR boosts when a shower is run the increased air flow rate and mixing from the "dry" extract ducts will reduce the humidity level at the MVHR. MVHR units are designed to deal with internal condensation, and usually have a condensate drain specifically to drain away any condensed moisture. It's not possible to "over run" an MVHR, sounds like a bit of hocus pocus that someone has made up, to me. Humidity will never get close to 100%, I think the very highest I've ever recorded on the extract side of ours is about 70%, and that was exceptional, it rarely rises above 60%. 10 minutes ago, Mr Punter said: I would want the unit to run flat out if I was having a shower.

I wonder if there is any proper science behind this? @Jeremy Harris surely cannot be wrong! Me too. We have ours set up with a humidistat, that boosts the MVHR when the humidity rises. It boosts a minute or so after the shower is turned on and stays in boost mode until the humidity drops below the trigger threshold (usually about ten minutes or so). I can be wrong, and have been, many times! 1 Link to comment Share on other sites More sharing options...

Looks very good to me, and seems to follow all the basic principles, like trying to maximise the path length across rooms, avoiding "dead" spaces and extracting overhead sources of high humidity.
