Experience with different ceiling valve brands

[James_H]

Hello all

 

I'm not quite ready for to do the full MEV to MVHR retrofit I posted about a while ago, but need to replace some ceiling valves.  There are a lot of valves around the £10 mark, but some fancier ones nearer £30 (or more).  I've seen a couple of posts on looks:

https://forum.buildhub.org.uk/topic/11560-ugly-mvhr-vents/

 

But something such as the Zehnder ComfoValve Luna looks interesting, as looking a bit neater than some others and supposedly offer acoustic benefits.  it talks of the Coanda effect for the supply valves.  The supply valve only handles 50m3/h (or about 14l/s), whereas the extract version will do 75m3/h (or 21l/s), so should be ok for the kitchen and family room needing one of each and 13l/s for the Part F requirement.

 

It does have fixed settings for balance at the valve, though I'd plan to do it at the manifold instead.

 

While £30 instead of £10, its not as excessive as the Lindab Airy needing various matching parts to be bought.

 

Any particular experience with this brand, or is the relatively few posts on valves themselves means they are much of a muchness and not worth going for anything special?
