We could fit in on the other wall which is 400mm ish wider, but this means having 50kg MVHR plus ducting attached to a stud wall / dry lined solid stone wall. Will it be strong enough or could we run into issues during installation or later on?

Lastly, is it right that the condensate drain needs to run at a gradual slope (ie gravity fed) or does the water get pumped out, and can this drain into a toilet cistern or internal soil pipe - or will that be horribly unpleasant? I'm not looking forward to running the condensate drain around 3 walls to get to the plumbing.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306942#Comment_306942 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306942#Comment_306942 Mon, 07 Oct 2024 11:53:21 +0100 djh Posted By: stonecoldwhat kind of elbow room is needed for servicing?The installation manuals normally specify what space is needed. As regards the ducting, do some drawings and buy at least some of the ducting parts and have a play. Or pay somebody to design it. All the plasterboard type materials have specs that state permitted loadings.

Condensate drains normally need to be gravity fed, yes, and you MUST use a dry trap (HepVO or similar) because the water in a wet trap will evaporate. Ours goes into a nearby foul waste pipe but any waste pipe is fine.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306945#Comment_306945 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306945#Comment_306945 Mon, 07 Oct 2024 17:55:32 +0100 Artiglio https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306946#Comment_306946 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=306946#Comment_306946 Mon, 07 Oct 2024 20:52:20 +0100 djh https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=307062#Comment_307062 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=307062#Comment_307062 Mon, 21 Oct 2024 13:28:03 +0100 stonecold https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=307066#Comment_307066 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18208&Focus=307066#Comment_307066 Mon, 21 Oct 2024 17:05:45 +0100 djh
