Moving (and changing) a radiator 2 meters, anything to consider

[Doran]

We are wanting to move a radiator around 2 meters to the side, as we are going to be placing a TV where it is presently located.
Also thinking about getting a slightly snazzier style to fit in with the syle of the flat (the present one is quite normal/average)

This is definitely not a job we can do ourselves so will get someone in, but is there anything to consider when getting a new radiator. size, heat output, positioning etc.
And is this a big job for a plumber? anything to consider here with options?

edit - On a side note, would I be right in thinking we should NOT place a brand new large TV in front of a radiator?

Thanks in advance

Consider getting a triple panel (K3) radiator to improve heating the room while setting the C/H flow temp lower

thanks for the tip, but had a look and we are looking for different style. Looking for ones similar to the pic below
And luckily we are a new build so heating doesn't get used much.

1. Measure the height and width of your existing radiator. Check to see if it has one front and one back heating panel and whether it has "fins". between the two. From the picture it looks like a type 11, which has a front heating panel and fins behind that panel with no rear heating panel. Use the dimensions and height to look up similar radiators to get the heat output.
2. Assuming the existing radiator keeps the room sufficiently warm:
2a. Find a radiator you like which give an equivalent heat.
2b. If you are going for the tall designer type radiators, I'd add 15% to the heat output requirement, as their circulation pattern is slightly different from normal radiators.
2c. If you want an element of guarding against reduced heat flow temperatures in the future, add 35% (more) onto the heat output requirement. If you already know your heating flow (boiler output) temperature you can calculate this more accurately.
3. Your pipework is behind the wall, so this will require minor construction work to re-route the pipes, and re-decorate afterwards.
4. Its not a particularly big job for a plumber, but a plumber is not necessarily the best person to make good afterwards. Try and find one who is, or try and fins a good handyman to make good, or indeed to do the plumbing as well.
5. Most heat (around 85%) from a radiator is not radiated heat, but convected heat. The radiator mostly heats the air around it, which rises to the ceiling and rolls round the room, cooling and descending on the far side. (One of the reason tall radiators can be less effective than low ones). Thus the radiated heat is relatively low. I'd leave a gap between a TV set and a radiator, but not a large one. 75 mm should suffice.
