    That is almost nothing! 2897 btus wouldn’t even do a small bedroom.
    1707 btus according to what calculations?
    The pipes should surely be straight up to valves.
    Rads can be chosen to suit joints positions.
    I really doubt it is difficult
    Get a heating installer rather than a builder.

    Just about enough for a cloak room toilet.

    1707 BTU is about 0.5 KW, so 1/3rd the size of a typical radiator for an average room. Always best to go large with Rads, quicker heating and lower temperatures.

    What size is the room - length, width and height? How many outside walls?
    What is insulation like in outside walls and floors and ceilings (if applicable)?
    New built well insulated homes have perhaps a third of the heat requirement in most rooms compared with a house of 50 plus years ago, but you still need to allow for condensing boilers working on lower temperatures and also severe winter weather.
    Generally only a few pounds extra to go a few sizes up in a radiator choice.

    Also, apart from BTU rating of rad, that tiny size in that room and under that window looks, frankly ridiculous

    Ok, that’s looking from a cosmetic angle so perhaps, not the most important feature but....., it just looks plain stupid

    Even if a longer rad is over specced in terms of output for that room, you could turn it down with a TRV and the whole thing would look a lot better anyway (also sorting out the pipes neatly of course)

    At the moment, rad looks like it’s come outta a dolls house and been put into a real house

    Something like a Stelrad Softline 600 x 1600 double panel plus P+ would look so much better and give out more than ample heat.

    1400mm would be ample & a bit cheaper.:)

    Room is 2.6x2.9x1.9. Two outside walls, 102mm brick, 100mm block, 100mm Rockwool. 0.28w/m2K. 100mm insulation above in pitched roof, 100mm insulation to room below. Fitting a bigger rad would get around the noggin issue as well.
