In my last post I was asking about replacing a missing cast iron radiator (which seemed more expensive than I was thinking). I wanted see what people thought of the following. 1. Replace the missing radiator with an identically size one from the bathroom. 2. Remove the bathroom from the loop. 3. Install electric radiant flooring. My thought is that it would kill two birds it would let me continue to use the existing cast iron radiators, plus it would allow me to independently control the temperature in the bathroom, potentially keeping it warmer in there for comfort and giving more flexability in avoiding freezing risk when we aren't there. Thoughts? Does anyone have experience with electric radiant heading? If so are there specific brands or installation methods that are preferable (using a mat vs. heating wire)?
