Lawrence, I would look into purchasing a radiator for that specific purpose before plunging into a project like that. The radiator that you have is designed to work by heating all the surfaces in the room its in. The floor the wall the furniture ect. An in wall type radiator wont waste heat or cause a potential problem by radiating heat into the wall. Also there are many other styles of modern radiators available that you may like better and be better suited for your space and heat requirements.
