I'm building a large built-in that covers a whole wall between the fireplace and the back wall of the house. To one side of the roughly 8 foot span is a hot water radiator, which is 4 feet long. It's a "modern", 1 foot high tyoe, not a big cast iron model. The built-in goes up and over the radiator, with about 5 inches of clearance below the cabinet. It doesn't get insanely hot in the cabinet, but I do want to route as much of the heat forward as possible. I've thought about designing a curved deflector to curve up from the wall right at the radiator, then curving forward under the cabinet, in hopes of diverting the heat to some extent. I also thought about insulating above the deflector, as well as covering the deflector itself (possibly .032" aluminium) with shiny foil to help reflect the heat. Has anyone had any experience with this sort of thing?
thanks,
