Balancing @ distribution box vs. valves

[tanneja]

For space saving reasons, I am drawn to the attached distribution boxes, they should give me the minimal run footprint for our small space.

They seem to come with restrictor rings to give someone the choice of distribution box based balancing rather than at valve.  I would think the unit is compatible with any brand ducting, and could be used without the restrictor rings if we so choose?

 

Has anyone got any real world understanding as to which would be preferable, since we would be doing the commissioning ourselves and our first time DIY.

 

Unsure at the moment of the best aesthetic vs. cost room valves, so knowing how i will use the distribution box will narrow things down a bit.  Any advice on the best valves that meets that description would be appreciated too.

Edit: as far as looks go, the square ones here look ok to my eye (https://www.phstore.co.uk/haelix), and cheaper than the BPC sold airy valves where you need to buy the cover plate, valve and clip separately.  However these ones only have 9 levels of restriction at the valve where most valves are continuous, would anyone expect an issue with that graduation?

I used these in my build and the MVHR was the one bit I did myself details at the blog.

You end up doing both majority of balancing at the box and some fine tuning at the valves.
