MVHR intake BEHIND cladding? Vents for black board on board cladding?

[markocosic]

Is is mad to consider pulling intake air from BEHIND cladding?

 

We have a board on board finish. 25x50 battens vertically every 600 mm. 25x75 battens horizontally every 600 mm. 150 x 25 board-on-board cladding on top of this; so a decent free area available for airflow:

 

 

It would be nice to pull from BEHIND this so as not to have any visible intake vent for the MVHR. 

 

Is this daft? Is there any scenario where we're going to deliver too much into the cladding by doing so?

 

(first thing in morning when ambient air is warmer than the wall that's cooled overnight?)

 

Else any ideas for neat vents for black board on board cladding?

 

The exhaust I had planned go drop through the floor into the 1 metre high / open all sides space underneath it (it's on groundscrews/piers) again to avoid a visible vent.

I would be worried about accessing the vents for cleaning, cobwebs dust etc on the intake. There may be an increase in VOC's from the timber, especial in warm weather. 

 

Having MVHR terminals on differing facades of the house can make it tricky to keep balanced in windy weather.

Mad idea for both supply and outlet.

 

Over thinking something that doesn't need fixing.
