Does anyone have a tankless water heater system? What are your opinions of it? We moved into our house a couple months ago and have horrible sulfur water. We've put in a culligan water system and replaced our anode rod in our water heater - neither have fixed the egg smell. I called a plumber and Locke Supply, both saying we need to replace the water heater. I'm wondering if a tankless system will help eliminate our problem rather than replacing a water heater every few years (the one in place is 4 years old). Thanks for any help!
