Fitting MVHR unit to the wall?

[Great_scot_selfbuild]

How are people fitting their MVHR unit to the wall? I’ll be unboxing ours this weekend and hoping that there’s some instructions inside, but I’ve had no detail on installation from the company (yet - have emailed, but waiting on a reply).

Ours is in plant room, which is lined with 25mm ply so you can easily mount anything anywhere.

Chose solid outside wall for MVHR unit so no risk of vibration noise traveling through timbers, when unit ages.

Sorry to hijack thread, but I would echo the above advice. My MVHR unit is directly fixed to a wooden backboard in the loft. I have noticed that the slight vibration generates a bit of noise as described above

 

In the case that you do NOT have an outside wall - is there any advice for some kind of dampener for the fixing?

Look at anti vibration mounts, neoprene dampers.

 

A Yoga mat might be enough to fit between the unit and the mounting board.

Ours is mounted on an offcut of 2x6 that has multiple fixings into our ICF external walls. Located in the plant room.

If it's a good quality unit and is set to run at low speed / duty, then you shouldn't be able to hear it (if it's a unit that will be accepted by PH standards), and I've never had any issue with these being on a stud wall of a TF (mostly MBC or English Bro's). Most of my clients have said how quiet my installs are, but if you're at 75% duty on trickle vs my remit of 40-45% on trickle then this may be an issue.

You don't need instructions, it's just a metal strip with a few holes in it. Then the unit hangs on it like a picture. You can fit qty 4 or qty 6 x 2" squares of 10mm thick neoprene on the rear of the unit which is likely more than suffice. Offer the bracket up and mark the holes, then see what you're screwing into there, beefing up according to what you need. Manufacturers and suppliers will just give you a generic reply re fitting, as you're not getting them to do it. Or you'll just get no reply at all.
