Undersized radiator?

[Jaybrian]

I have had some old radiators replaced. Having checked the btu calculation myself, the new radiator is slightly undersized. It should have been 6150 btus, and the k1 rad that has been fitted (the required width in order to fit the old pipes) is 6025 btus. Output wise the next rad up would be a p+ which has a rating of 8367btus. Is the k1 rad ok, as the alternative is much bigger than required. Thoughts please!

I tend to fit over the odds , but new regs say fit as for ashp, you have trv"s fitted so you can dail down.

I already have the rad fitted. Do you think such a small difference would affect overall performance?

not that you would notice.

Are those outputs at the same delta T?
125 btu is very very roughly and approximately half of what you are giving off whilst typing these posts.
