hendriQ Posted February 28, 2021 Share Posted February 28, 2021 I’m trying to figure out whether it’s a bad idea to site my MVHR in a hard to access part of my loft. If I need to access it once every 4 months or so that would be fine, but any more regular than that would be annoying (in which case I will change my layout).

Oz07 Posted February 28, 2021 Share Posted February 28, 2021 my filter light seems to come on every 4 months. Cant think of any other reason access is needed. The filter light comes up on control panel so wouldn't have to access machine to check Link to comment Share on other sites More sharing options...
MJNewton Posted February 28, 2021 Share Posted February 28, 2021 Other than changing filters every six months I don't go near it. There is obviously the installation aspect to consider but that's a one-off. Link to comment Share on other sites More sharing options...

I used to be able to crawl along the triangle formed by our front eaves to access the loft where all the cables go down into the cu along with various pipes that run down there. There's a fair chance now I'd get stuck and have a clutcher! 1 Link to comment Share on other sites More sharing options...

Is the position too tight to be able to remove the heat exchanger if required. Your MIs may suggest an annual clean. Link to comment Share on other sites More sharing options...
Roundtuit Posted February 28, 2021 Share Posted February 28, 2021 (edited) Frequency shouldn't be a problem, but if 'hard to access' means 'confined space', just make sure you've enough space to be able to carry out routine maintenance i.e pulling our the heat exchanger for cleaning.

For a unit that is about 750mm high, 450 wide and about 500mm deep how much space do you think is necessary? The area I have in mind is about 2m high and 1.5m deep, but very narrow. Probably around 1.1m in width. Link to comment Share on other sites More sharing options...
Oz07 Posted February 28, 2021 Share Posted February 28, 2021 More than you think for all the pipes above it Link to comment Share on other sites More sharing options...
Oz07 Posted February 28, 2021 Share Posted February 28, 2021 Where will you put manifolds if you have in the same cupboard/area? Link to comment Share on other sites More sharing options...

Maintenance on our is pretty much all from the front. As @Oz07 said, the ducting, silencer, manifolds etc do take up more space than you'd think, so it's worth spending some time planning it out.

NSS Posted February 28, 2021 Share Posted February 28, 2021 (edited) Be mindful also to where any condensate drain exits from the unit Edited February 28, 2021 by NSS Link to comment Share on other sites More sharing options...
