EcoSmart warranty for water heaters
The short version
EcoSmart doesn't cover everything, but keeps water heater (eco 8-36) and leaks (eco minitank) covered for life. That full coverage is the same as most of the 11 brands we compared, which typically cover nothing in full. Some of this coverage only applies if you register the product.
From EcoSmart's published warranty, checked October 2026.
