We're in the process of remodeling our bathroom are expanding its size by capturing a few feet from a walk in closet. By doing so, we're going to be intersecting a baseboard radiator that runs on the outside wall about 4 feet of the 3 feet we want to capture. I'd prefer not to have to alter the hydronic system, so my questions are as follows: can I remove the radiator cover/reflector, wrap the pipe and fins in insulation and then build the wall over/around it? I would then build the tub platform over the then-insulated radiator in what will be the new bathroom. We intend to install radiant floor heating under the tile, so I'm not concerned about the overall heat situation in the to-be larger bathroom. Boiler system is a loop system, with the entire 2nd floor on one zone, furnace cut-out temp is set at 160 degrees in the winter.
Any thoughts/advice is appreciated.
