Rheem warranty for water heaters

30/100 Warranty ScoreRanked 6 of 11 brandsCheck your model's manual
The short version

Rheem doesn't cover everything, but keeps tank and component parts covered to 8 years. That full coverage is the same as most of the 11 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.

From Rheem's published warranty, checked October 2026.

What it leaves out

  • Leaks
  • Stopping working from outside causes
  • Water damage
Good to know before you buy
  • Covers the original owner only and can't be transferred.
  • Coverage starts on the installation date, so keep your installer's invoice.
  • Labor, permits, and removal of the old heater are never covered.
  • If the heater is not in a single-family home, coverage drops to 1 year.
