Which water heater brand is the most reliable?
It is unclear if there are real build differences between brands, or if buyers are simply paying for 6-, 9-, or 12-year warranties. This choice is further complicated because manufacturers often restrict direct consumer purchases and refuse to warranty DIY installations. Consequently, people cannot confidently buy a unit, fearing it will fail exactly when the standard warranty expires.
