Eccotemp Water Heater Warranty — Coverage, Registration & Claims

Eccotemp water heater warranty terms vary by product line — point-of-use units typically have shorter warranties than whole-house tankless systems, and commercial models have stricter coverage limitations.

Typical Eccotemp warranty terms

Specific terms vary by model — verify with the warranty card included with your unit.

What's covered

• Heat exchanger or heating element defects within rated period
• Control board and electronic component failures within parts-warranty period
• Manufacturer workmanship defects evident from first use

What's NOT covered

• Damage from improper installation (wrong electrical sizing, gas pressure, water pressure)
• Hard-water mineral damage (descaling failure)
• Damage from water quality outside published spec (chloride limits, TDS limits)
• Freeze damage
• Use in unintended applications (residential unit in commercial use)
• Damage from third-party additives or non-OEM parts
• Cosmetic damage and shipping marks
• Consequential damage (water damage to flooring, contents)

Filing a Eccotemp warranty claim

1. Document failure with photos including Eccotemp data plate
2. Identify model and manufacture date
3. Contact Eccotemp customer service for warranty assessment
4. Provide proof of purchase and installation
5. Be prepared to demonstrate proper installation and maintenance (descaling records for hard-water-area claims)
6. Replacement parts shipped or, for major failures, full unit replacement under valid claim

Critical warranty considerations

• Registration: Some Eccotemp models require registration within 30–60 days of installation for full warranty
• Installation by licensed professional: may be required for some commercial models
• Descaling records: hard-water-area claims often require evidence of proper maintenance
• Water quality testing: if claim involves heat-exchanger failure, Eccotemp may request water test results
