I'm replacing the heating system in my new place and would like another opinion before I go ahead.

The house is an old Victorian place so I'd like to fit column radiators but due to low window restrictions I think I'm going to fit vertical versions to most rooms apart from the hallway and bathroom.

How does the following sound?

 
Am I reading it wrong then? The 2000mm x 490mm is 6244BTU/1830W and the one you linked is 2054BTU/602W
 
sorry mate I linked the wrong one

but yes the equivalent conventional radiator will output far more heat than a column decorative radiator.
 
I know that but all of the radiators I've listed are pretty powerful aren't they? I understand that convector radiators would be cheaper but I much prefer the decorative ones as they're more in keeping with the overall age and style of the house.

Your house would not have had radiators so nothing is strictly in style! I'd think seriously before putting vertical column radiatorsthe in every room consider how visible they will be and sort furniture placement there is a reason people normally put rads under windows!
 
Ok, technically not in style but more in keeping with it than flat convector radiators.
The reason for vertical radiators is because the windows are very low so I'd be limited to a max of 500mm high radiators so in order to get close to the BTU required for horizontal column radiators they'd have to be almost 2m long (ie wider than the windows)
 
As someone who owns a Victorian house (london, 1896), I kind of know where you're coming from, especially as I also lived in a post war council flat with lovely cast iron rads. My house still has pipes for the gas lights and for the bell system to "ring for tea" under the floor boards...! But a building needs to evolve with the times, not be pickled in aspic. I'm not sure that those vertical rads are really "in keeping" and (to me) they look a bit like trendy bathroom radiators. I'd just get a modern, efficient double rad under the window and not try and make a feature of them. Google indicated that you can get a 400x1200cm rad that pumps out 5758 BTU.
 
We had a vertical rad in a previous house and it was terrible. You couldn't feel the heat until you were almost touching it.

If you dont want "normal" rads then look at Cast iron ones. You can get the specced up to how you wan them.
 
Also, for maximum thermal efficiency, you really want a reflective panel behind the rad so you don't waste energy on heating up the wall, esp. on an outside wall. You can only get away (esthetically) with a refelctive panel when using a modern rad.
 
How come the advert on eBay says 1780 x 590 x 78mm 3,697W 12,615BTU yet the additional information on the Milano page says BTU 7093 and then further down the same page it says BTU at △T30 2,531 and BTU at △T50 5,000

Which is the correct one? We've got a range of 2531 to 12,615, that's a huge difference!

There is, it was to do with convection (physics), and the rad under the window meant it was warm air being drawn round rather than cold air from the window which would have made it feel more drafty!

If you have double or triple glazing then thats fairly irrelevant now but its a handy spot as plenty of people dont want to put anything under the window.

tldr; Rad placement used to be important, only is now if you have single glazing only

Still relevant if you have large double glazed windows as you get a cold spot next to them.

They are probably all correct at different deltas, welcome to a world without standardised measures!

Generally speaking pretty radiators perform much worse than a standard modern panel radiator. Personally I'd install the pretty one that you think has enough btu as you can always swap it for something more powerful at a later date!

We have just done this in our kitchen we wanted some traditional style column rads so we have over specced the btu and will swap one out for a modern panel if come the winter we lack heat!

I think I'll do similar and just buy the original tall vertical radiators as they are the best compromise. Even if they aren't as powerful as convector radiators they should still be powerful enough for the rooms.
I'll put two in the living room just to be extra safe.

Cold spot yes, but its not the same it doesn't create the draft like it did with single glazing as its far less of a temperature differential

Edit, here you go https://www.first-utility.com/the-utility-room/energy-uncovered/radiators-under-windows
"Advances in double or even triple glazing means this practice is less important and in newer homes radiators can be placed anywhere in the room without the draught issues."
