I really rate the heavy industry kit. They get a hard time from Mitsu-elec in the industry, as they don't like to be associated but in all fairness the first time I put a heavy industry system in was 5 years ago, I've put plenty in since then-not a single come back.

My experiences of Daikins VRF haven't been great, I had some really cr$ppy encounters with there kit in a very stressful retail environmnet, there tech support, and aftersales really didn't help on that occasion, but that's just my own experience don't forget.

It's swings and roundabouts, others rate them, and slate companies I've personally never had a complaint about, I'm affraid it does tend to boil down to personal experience.....take the plunge and see what you think!

Mitsu heavy prices havbe got to compare favourably over Daikin though surely??

All the best with the project!
