Alan Ambrose Posted July 27 Posted July 27 Apologies for another brand comparison re-hash: The Brink is about £3.9K vs. £2.3K for the Zehnder i.e. about 70% premium. This is for a requirement of 160 normal/210 boost m^3 /h and so the Brink is about 1.9X oversize and the Zehnder 2.2X. Am I missing something?
Alan Ambrose Posted July 27 Author Posted July 27 And a bonus question - assuming a bit of wired switch / app control - what connectivity options have you chosen for each of these. I see this for the Zehnder: and this for the Ubbink:
Alan Ambrose Posted July 27 Author Posted July 27 For anyone following along at home: The difference between the Brink Flair 400 and the Brink Flair 400 Plus is the inclusion of an upgraded Plus PCB board (i.e. it includes the UWA2-E board). This enables "the Brink Home online and app control via (W)LAN internet connectivity and also extra analog inputs, digital inputs, and terminal connections for advanced accessories like post-heaters or complex multi-zone sensor setups." The base model includes "standard connectivity like eBus, Modbus for building management, RJ12, and USB port for an RF dongle. Also, basic local control via integrated display or 4-way switch." Price difference is about £300 - in the UK I think by buying the 'E' board separately. 1
Alan Ambrose Posted July 27 Author Posted July 27 The Zehnder box seems to require the 'ComfoConnect PRO' add-on at about £250 for LAN / wireless / modbus.

Ping me a PM when you’re ready to buy We’ve been here, Brink is often the winner on price / performance and more; CVC Systems in Oxford have not once let me or my clients down, ever. Passivhaus certification where I’ve needed it, and beyond. Fitted a Zehnder recently, nothing to report wrt boosted quality etc tbh. Black PVC tape to mask the unit during handling, so it didn’t get scratched. I think the tightest plant space I have ever managed to squeeze one into lol. I suggested a Brink here, physically smaller unit which would have done a plenty-good-enough job, but the client went supersized for zero reward, but hey 🤷♂️, if you’ve got the money and know better……..

It was all accessible. Tight as feck, but I made it work. Sat the unit on 2x neoprene clad 3x2” feet, so it could be lowered down and replaced if necessary, but in reality everything is changeable from the front panel. All good, I made it to be so Got zero thanks, but 🤷♂️, we move lol 1

My Brink 400 was a little less than £2k on his advice. Which reminds me, and on the subject of thanks @NickfromwalesIf i forgot previously a huge thankyou for the tip. 3
Alan Ambrose Posted 6 hours ago Author Posted 6 hours ago OK a bit more info: + the Zehnder unit has the benefit of not being 'handed' (as it's switchable) but the drawback is that it's quite a lot physically taller - 850mm vs. 650mm. + the Brink unit seems to be consistently £600 more expensive than the Zehnder. + the Brink Vigor / Flair etc brand confusion doesn't inspire confidence. Which organisation will be supporting? Neither was my experience of their duct system which seem half-baked ... just like someone on their design team had never ever tried to install it. + both Brink & Zehnder seem to need an extra bit of electronics for web control. Although, in the end the built-in RS485 / Modbus might be the best control solution. According to Google AI (which I have not verified) the Brink units need an actual internet connection for the app to work, the Zehnder units don't. While the bigger physical size is a pain, I'm leaning towards the Zehnder unit. 1
