Hello fellow DIYers and those helpful professionals. Apart from the size difference (and any piping alterations that may be required), are there any advantages/disadvantages to fitting for example a K1 single convector rad or a K2 double convector rad or even A P+ rad all of the same BTU output? In my particular case I need to supply about 12000 BTU with 3 rads.
Thanks in advance for your help.

The differences between the types of rad are purely cosmetic or simply to cater for different room sizes.

Hi plumbbob. Thank you for your reply.
