I'm looking at swapping 2, 1100 wide by 500 heigh single panel converter radiators for two tower column radiators. The existing are about 890 watts each. The columns will be 440 wide 1800 heigh a single in those are 850watts. A double is 1250 watts. Would I be best of with the double column or single? Thanka

Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
Tower column rads

IMO the more surface area the better and with TRV's, overheating won't be a problem. The greater the surface area, the quicker your room will heat up and the TRV's start to throttle back. In my house, all of the rads are completely oversized because I run my system at a max flow temp of 55c and I also require a rapid warm up before my slow-moving disabled wife rises each morning.
So you'd probably go with the double columns and maybe be a tad over sized. These radiators transfer heat via radiation not convention. So best of being abit over sized as opposed to standard convertor radiators?
If you are talking about 1800mm high tubular type designer radiators. then unfortunately you cant compare these 2 types of radiators side by side. If the original radiator were Type11's, so single panel single convectors, then the way they heat the space is completely different.
Unless the room is relatively small then they will take a lot longer to sufficiently heat the space. If it's a relatively large space then the room may not heat up properly at all.

Yes it is realativley small. I know they heat via radiation. Hence why I thought over sizing the btu rating.
I looked into designer rads and they were all style over substance - had to have massive things as a feature on a wall to get the same real world output as a lower/ longer more discreet "normal" rad so went with that.
You can yes, I'd usually go at least 50% larger by output but no matter how large they are, anything out with say 4 feet will not receive any real heat by the emitters radiation therefore using it's relatively small convection properties, it can take a lot longer to heat the space.
They can work in certain rooms, bathrooms, bedrooms etc where furniture etc are closer but when it comes to larger open spaces like open plan living room/kitchens etc then they can be really poor at heating those spaces as things tend to be much further away
