The ever-dependable James, who is a professional plumber, takes you step by step through the process of removing a small radiator and replacing it with a big one. In this particular case, this room has a small radiator oddly positioned to the side of a long window.
The rad is not sufficient to heat the room and also doesn't look particularly aesthetically pleasing. James goes through taking out the old rad, measuring up to install the new one symmetrically and he also re-routes the pipework under the floorboards.
A must-watch and incredibly useful video to help provide a solution to this common problem!
