    Hi guys, I am deeply pressured at present with in-laws arriving in 2 weeks just for starters so I could really use a pointer. I need a HR Unit the spec for which seems to fall between single room ducted units and small MVHR units. It has to be ducted; it will be extracting internally from 1 position (6m run) and supplying internally to 2 positions (1m and 4m runs ) and it would really, really, help if the external spigots and internal spigots were at either end of the Unit ie for fitting up onto a ceiling. The good thing is price is no object (within reason).

    I have only found 2 Units like this: the Xpelair Xcell 150 (but Specific Fan Power 3.2 W/l/s:cry:) and the Vent Axia HR200V which is only 70% efficient max and is nowhere near balanced (supply 40% Extract 60%). I am very happy to use a more powerful unit than I need, especially as I think it is much better to use a unit on low power than use one on full power but the more powerful units are Whole House and are much bigger and have spigots all on one face meaning U bends and crossing ducting in a very tight space.

    There must surely be a better option out there? Otherwise it's the second hand (new) DV75 on sale here, the 3.2SFP thing or the 70% unbalanced thing.

    Zehnder Comfoair 160 can go on ceiling - I'm looking at it for approx 70m2 floor plan, single storey.

    Great, thanks seascape, specs look good - can't actually find it for sale on Internet, even went to 4th page on Google (unheard of), have found distributor details, in Rustington (not 2 miles away from where i used to live and where I want it delivered!!) - have sent E Mail to them but how much is this thing - do you have any idea?

    Ha found it! - would you believe it is Italian, where I live now. BUT they list its price as 2400 Euros, well over £2000 which is ridiculous, surely this isn't selling at more than double it nearest most expensive remotely comparable product in the UK........for example have just found this MRXBOX95LP1 at £961 higher spec, half the SFP, better capacity, more flexibility all around, a real Rolls Royce at under £1000.
