Radiators... Talk to me - Please

Are the pipes fastened in to the wall? How big is the room? Any aesthetic considerations?

Pipes are coming up from the floor so will be replacing like for like size wise.

Replacing very very very old single panel radiators.

Will post sizes later but they are very wide. Is a Victorian semi, front and rear living rooms with high ceilings.

Assuming I know the BTU values etc, what design of rad is most efficient?

Are vertical radiators efficient?

Also, if mounting a radiator ABOVE french doors, is this even a sensible option? Physics tells me not but you never know :D

I thought new rad designs pushed warm air through the top and bottom?

The required BTU for the back room is about 7500 BTU.

2 external walls.
2.6m window space

That limits my rad choice unless I want to have 2 radiators.

Well, most of the BTU calculators say around 7500 BTU for the back room, so taking into account inaccuracies and a cold house, I am getting a 9500 BTU rad. No harm in over speccing is there?

The thing is, I do not want to be removing pipes (concrete floor) so has to be a 2000mm rad anyway.
 
Right...

The old rad was imperial, 2150mm.

The pipes are buried in concrete so moving them is not an option.

So, the rad size choices are:

2000mm
This will need the pipes/tails returning in by 75mm each end.

I fear this will look ugly?

2200mm
This will need pipes/tails being extended by 25mm each end.

Is this an easy task?

I am not doing it, Plumber is booked for Wednesday :D

If so, is this any good:

ooh, or this one:

Does one go for a 500 or 600mm height? Aesthetically, does it make a big difference?
T21 vs T22 - The depth difference makes a T22 rather "chunky" in my opinion.

Perosnally, I would rather have the extra height but less depth.

If you have 1 large room, I assume not having enough BTU at one end and compensating for it in the other just means one room is cold and the other is too hot right?
 
Got a P+/K1/T1 radiator in the end (Double panel, single convector) for the back room, was fitted today.

Went with 2200mm in the end and luckily, it fitted where the imperial Rad was with no additional joints. The imperial rad was about 2150mm ish.

Turns out the old pipe work had some "play" to it so squeezed bits in and worked a treat which was lucky as looks much tidier.

P+ and K1 are different, P+ is a Type 21, K1 is a Type 11. Always confuses me all the different terms, Type is the easiest i find, first number the number of panels, second number the number of convectors.

Bonus that it went on so easy. Why not go for a Type 22 though minimal extra cost for a decent increase in output.

Too deep, would stick out too much.
