A: The first thing you should always do is calculate the power you need for the space.
You can do this using the BTU Calculator on the Beat Heating website. You’ll then know how many radiators you’re likely to need and what power they need to generate.
You then need to see what wall space you’ve got to work with. Have you got dead spaces underneath windows that you can utilise? If so, a horizontal design with two or three columns would make best use of the space. If you’ve got narrow wall spaces but need a lot of heat, then vertical radiators make better use of the height.
Typically, you want to try and avoid radiators being behind large pieces of furniture. But if that can’t be avoided then think about how you can allow the heat to penetrate the room. That can be choosing a lower sofa or piece of furniture, opting for an open desk that a radiator can be placed beneath.
Basically, you can place your radiator anywhere really. You just need to know you’ve got enough heat pumping out of it and enough wall space to hang it!
