Type 21 or 22 radiator to replace old one?

[Abs4190]

Hi guys , I'm looking at replacing an old radiator in the dining room with a newer on .. I've seen the kudok ones at screwfix and TS. Would you go for the type 21 or 22 radiator. I'm after 900 x 600. My old radiator is 960 x 540 so I'll grab a 60mm radiator extension valve as well. Thanks in advance.

I'd go for a 22. You'll need to alter the pipes either way as both a 21 and a 22 will have the pipe centres further from the wall than the current radiator. It'll save you buying extension tails though
