SW Standard owners
- Praise: reliable when maintained; widely available parts; established RV technician familiarity
- Complaints: anode rod replacement needed annually (vs Atwood\'s no anode); spider screen cleaning required; LP-only models notably loud burner
SAW Advance owners
- Praise: noticeably faster recovery; quieter than SW Standard; worth the $100-150 premium for active families
- Complaints: not available in all sizes
Nautilus tankless owners
- Praise: never run out of hot water; no anode rod worry; lighter weight
- Complaints: 2.4 GPM limits flow; low-flow aerators may not activate the unit; more complex troubleshooting than tank
Common across all lines
- Anode rod replacement is the #1 maintenance task owners report
- Spider/wasp nests in burner intake are the #1 cause of "won\'t ignite" calls
- Winterizing skipped in even one cold season has caused tank failures
