Dandy Air did my head in! It wasn't until the owner came out for himself with a tradie that the issues got resolved (and even then it was not right until Brivis came out a year later
I only skimmed over these posts the other day... now I have something to add because I've just learned that these guys have installed our Brivis system... when I say 'installed', it's half complete! After getting up on a ladder it appears our unit is safely chocked up on some thin chipboard... then on top of that some timber offcuts, then on top of that some bricks
In addition to the platform they've put in place, the whole unit also sits directly over where my range hood needs to vent through the kitchen ceiling. Dandy Air are stars! Our builder (Henley) are now in debates with ***** *** about their installation procedures blah blah blah... our issue will be resolved in the next few days.
