Recently purchased 9 year old house with well water. Sulfur odor hot water side only. I am looking to replace 9 year old water heater rather than simply try a new anode rod. Tankless hot water system is more than we would like to spend. Rich Trethewey has a page that mentions stainless steel hot water tanks for some situations. This seems like a possible solution to the odor problem since no anode rod required with stainless steel tank. I was told by plumber that a stainless steel tank requires a separate heating device. I am writing to find out if there are residential stainless steel hot water heaters on the market. If anyone knows of one, would you be able to provide me with the manufacturer(s) name(s)? Thanks very much.
