Wanting to remodel my kitchen this year but still up in the air about heating. Currently there is a single cast iron radiator against the exterior wall under a narrow countertop. I'd like to place full sized cupboards/countertop down the entire exterior wall, so this is an issue. A friend of mine put in an electric heat mat under new tile and likes it, and since I'm planning on replacing the worn out hardwood with tile, that is an option. What I imagine as the best fix is to remove the radiator and somehow use the same water supply to heat a baseboard that could be in the toe space under the entire span of cabinets. Has anyone ever seen anything like that or have ideas about potential issues? The way I imagine it working is some cast iron to copper conversion, then plumbing a loop under/between the cabinets and back, so no other plumbing need be disturbed. Thoughts???
