I am bummed about washing my hands in cold water since chemo last year. 15 year old electric 80 gal water heater works well, but occasionally notice rotten egg smell, not yet consistent. Recently read that tankless water heating (close to fawcet?) would last 20 years. I recon it would take another 220 breaker and heavy wiring for each tankless heater, right? But for twenty years. I get no special elec. rate for water heating. Utility is pushing an eco-type using a compressor? and due to successful geo furnace experience, it looks attractive, but that is a lot more moving parts, relays, etc. which in my experience HAS been a small problem. And it does not give with quick on demand warm water. So has anyone used tankless heating and been happy with it and the bills? Thanks, Leo
