I've git a single-skinned hot water radiator (thin, modern type) that I want to install in my bathroom. It has no fins on it. It's size is about
25% bigger than the existing radiator, but the existing one has fins... Is there a rule of thumb that says how much bigger a non-finned radiator needs to be in order to equal the heat output of a finned radiator?TIA

Another way is to look at some figures for comparable types on sale now (manufacturer data is pretty good on the better ones) and work out a fudge factor.

Thanks re bith replies. TBH, I wasn't aware that single-leaf rads were still available! The 1.5x ballpark figure is good enough for my purposes.
