I wouldn't have thought for all that long! Mind you. maybe the OP has a source of 400V single-phase heatersProbably not immediately. Would certainly improve the heat output significantly.Bang?

3 balanced 230V loads across 3 phases with a common star point will work just fine. No different to the 3 windings in a TP motor.
Indeed so. However, the last three or four posts have been about phase-to-phase (i.e. 'delta') connection of the heaters, which is a whole different scenario!
With the star arrangement of heaters, one would presumably have to hope that they didn't have individual thermostats (and that none of them ever became faulty), since that would play havoc with the 'balance'

John. My post was not responding to you and you missed my point. I asked the OP about his background because this is not a diy job. I referred to early posts saying this, which the OP ignored. My point is that he will be responsible for the installation, not any forum members who give advice. Given his posts, I don't know any electrician who would give advice other than get a pro to do the job.
There are plenty of instances where a poster wants to ignore the law and the approach is to advise to try to keep them safe. Usually when doing a notifiable job and the poster wants to ignore his labc. The pragmatic approach being to help him do a safe job.
A 3ph board, in a commercial premises is not a place for a diyer (or an electrician who needs design advice from any internet forum) to be working.
My point to the OP, as bas picked up, is that he is asuming responsibility for the installation not any forum member giving advice. I never said forum member would face prosecution. I have editted my post, to hopefully clarify my meaning.

Can't help but think often, if forum contributors (and that includes other forum(s?)) made a little effort to check ... and then improve where necessary the punctuation in their postings, a lot of misunderstandings could (sometimes ) be avoided.
Now children ... sit up straight.

That's very true, and it's not just punctuation - I imagine that we are all guilty of writing ambiguous things in our posts sometimes!Can't help but think often, if forum contributors (and that includes other forum(s?)) made a little effort to check ... and then improve where necessary the punctuation in their postings, a lot of misunderstandings could (sometimes

Is that a serious comment, or did you forget to add a smiley? If the former, then you are definitely misunderstanding, and I could attempt to explain if you wished.
Kind Regards, John
I don't think many 'knowledgeable' non-electricians would, either - the OP has certainly not obtained any significant advice regarding "how to do it" from anyone. Thanks for clarifying, and my apologies for misinterpreting your post.
Thanks for editing. There is no longer any ambiguity or scope for dim people like me to misunderstand!
Indeed, although at least some disapprove of that pragmatic ('risk mitigation') approach. However, that's not the scenario we are dealing with here - although I suppose there would again be a bit of a dilemma (for forum members) if the OP made it clear that he was hell-bent on going ahead with the work, with or without advice. However, fortrunately, he has taken the advice to employ an electrician..
Quite so - and, as I have pointed out, I (a non-electrician) told the OP that in post #2.

Any advice as to whether the 3 x 3kw convector heaters are sufficient to heat the area?
I'm no authority on such matters, but you could investigate this as well as I can - there are innumerable 'calculators' on-line. Having had a quick peep, it looks as if what you you propose may possibly be just about adequate - but who knows?!
How was it previously heated, or did it just rely on the sunbeds?!
Kind Regards, John
Fair enough.
Again, fair enough - it doesn't matter whether you calculate in kWs (not kWhs) or BTUs and then convert to kW.
