worth changing type 21 radiator panels?

[GinGaz]

Got 3 small rads 800 x 600 that could do with replacing as are becoming quite corroded .....
Would there be any point changing from type 21 to 22 when buying new ones?

You need to find out if those radiators are correctly sized for the room.

There are online 'radiator calculator' that will give you an indication, and go from there.

If you are happy with the performance of the rads and the rooms are comfortable then stick with what you have

I don't want to change the size of the panels as i don't want to change any pipe work .... just wondered if anyone thought the slightly higher output would be worth it ....

Are they currently up to the job of heating the room? If yes, stick with the same, if no, get the larger type.
