Fundamentals of Tankless Water Heater Warranty

When you invest in a tankless water heater, you’re also investing in the peace of mind that comes with a warranty. It’s essential to grasp what is covered and for how long so you can fully understand the protections in place.

Coverage Basics

Your tankless water heater warranty typically covers defects in workmanship and materials. Most warranties will protect the water tank and internal parts, ensuring that if something doesn’t function as it should due to manufacturing faults, you won’t be left with the expenses.

This kind of protection often includes the labor costs related to the repair or replacement of defective components.

To illustrate, Rheem tankless water heaters come with a warranty that offers coverage for different parts and scenarios, according to the specific model you own.

Duration of Warranty

The length of your warranty varies by manufacturer and model. Generally, you can expect tankless water heater warranties to last between 5 and 15 years.

For example, a Navien tankless water heater includes a 15 year limited warranty on heat exchangers for some models, which are crucial components of your system.

However, the parts and labor might be covered for shorter periods, such as 5 years and 1 year respectively.

It is imperative that you check the particulars for your specific model to determine the exact durations each aspect of your unit is covered.

Making a Warranty Claim

When your tankless water heater faces issues, making a warranty claim might seem daunting. Knowing what documents you need and understanding the steps to file a claim can expedite the process.

Before you begin, gather the necessary paperwork, which typically includes:

  • Proof of Purchase: Ensure you have the receipt or invoice showing the purchase date and place.
  • Warranty Certificate: Your warranty information is crucial to ascertain the coverage.
  • Serial Number: Find the serial number on the unit; it’s required for identification.
  • Service Records: If you’ve had any service done, these records might be needed to show proper maintenance.

Claim Process Steps

Follow these steps to make your warranty claim:

  1. Read Your Warranty: Understand the coverages with information from their manufacturer.
  2. Contact Customer Service: Reach out to the manufacturer or retailer, often through a hotline or online platform.
  3. Provide Details: Share the issue and provide the documentation, confirming if the problem falls under warranty.
  4. Schedule Inspection/Service: The company might schedule a service visit to inspect or fix the unit.
  5. Follow Up: Keep in touch with the service provider to ensure your claim is progressing.

By preparing the necessary documentation and understanding the steps to file a claim, you’ll be better equipped to handle any issues with your tankless water heater under warranty.
