K3 Triple panel radiator

[RedQueenie]

Hiya, I was hoping I might get some feedback from people that have installed K3 triple panel radiators.
I'm thinking of having one fitted. I like the idea of them being smaller and still giving out the same heat, but was just wondering if that is the case?
I'm currently looking for a high output of about 9000btu. Logic is telling me to go for a wide and high Type 22 panel as it has a bigger surface area, but if I can get the same heat output with something smaller and wider that would be great.

A K3 is basically a K1(type 11) and a K2 (type 22) stuck together. So you get 3 panels and 3 sets of fins. They are thicker and project from the wall (into the room) further. They are also heavier so the wall needs to be stable/supportive.

They work exactly the same as any other conventional convection radiator and heat the space just as efficiently.

Stelrad radiator sizes and outputs,

Hi, thank you for taking the time to reply.
I'm just trying to get my head around how it can give out so much heat and still be smaller

Shorter in height but wider.
