Type 22 vs Type 21 radiators

[JohnW2]

I undertook some comparisons of Type 21 and Type 22 radiators, and it seems that with most makes and most suppliers, for a given height and heat output the price of Type 21 and 22 ones is much the same, the difference being that (due to less fins) the Type 21 are generally about 200 mm wider (for a given height and heat output).

That being the cases, is there ever any reason for favouring Type 21s ?>

Kind Regards, John

Yes I had this scenario and opted fro the type 21 because it did not stick out so far.

Ah, right, I didn't realise that, although I suppose I should have realised that such would be the case! Roughly how much deeper are the 22s?

Not a massive difference but it was enough of a difference for me especially due to the position the rad was fitted - also I was swapping an old one for another and did not want to alter the vale positions which have different centres on 21 and 22.
I think different manufactures have different code like p1 and p1+ p2+ indicating 1 panel plus fins ect

Yes, I've just had a look at one make, and the 21's are 67mm deep, whilst the 22's are 100mm deep - so, although 50% deeper, that's only a difference of 33mm.
