  1. In the big steel mills, they heat metals to liquid state in giant vats that are cool to the touch. They are painted with a heat resistant paint. I used this myself probably over twenty years ago to paint exposed hot water pipes along floor baselines. This completely eliminated any loss of heat and any chance of getting burned touching a hot water line. The pipes could even be covered by regular paint in order to blend in. The company did not normally sell to non industrial users and it was expensive. I discussed the possibility of using this paint on the walls and ceiling instead of insulation and they said that it should work. I couldn’t afford it so did not pursue. It significantly lowered the cost of heating the water.
