WCN on a water heater refers to the Water Connection Number, identifying the specific water supply connection for efficient operation.
If you’ve noticed “WCN” on your water heater’s documentation or model number, you’re likely wondering what it means. WCN stands for Water Control Number, a unique identifier manufacturers use to track specifications and warranty information for specific water heater models.
Understanding WCN in Water Heater Model Numbers
The WCN typically appears as part of a water heater’s model number. For example, in the model “ELU-150WCN,” the WCN suffix indicates specific technical specifications for that unit. Manufacturers use these codes to:
- Identify exact product configurations
- Track warranty coverage
- Determine compatible replacement parts
- Maintain service records
How WCN Affects Your Water Heater Warranty
Your water heater’s WCN plays a crucial role in warranty claims. According to U.S. Water Heating Solutions, manufacturers require this identifier when processing warranty service requests. The WCN helps them:
- Verify your unit’s production details
- Confirm remaining warranty coverage
- Determine which components are covered
- Process claims more efficiently
Where to Find Your Water Heater’s WCN
Locate your WCN in these common places:
| Location | Description |
|---|---|
| Manufacturer’s label | Typically on the side of the tank near the serial number |
| Installation manual | First few pages or specifications section |
| Purchase receipt | Listed with the model number |
| Warranty card | Printed on registration documents |
Why WCN Matters for Repairs and Replacements
When ordering parts or scheduling service, technicians will ask for your WCN to ensure compatibility. For example, the best water heater element wrench for your model depends on specifications tied to your WCN.
WCN vs. Other Water Heater Identification Codes
While WCN identifies control specifications, water heaters have other important codes:
- Serial Number: Unique to your specific unit
- Model Number: Identifies the product line
- Date Code: Shows manufacturing date
- ANSI Certification: Safety standard compliance
How WCN Relates to Water Heater Efficiency
The WCN often indicates efficiency features. For instance, HTP’s Elite Ultra models with WCN suffixes feature advanced heat exchangers that provide 150-450% greater opening area than traditional designs.
When You’ll Need Your WCN
Keep your WCN handy for these situations:
- Registering your warranty
- Scheduling repairs
- Ordering replacement parts like the best water heater thermostat control
- Troubleshooting with manufacturer support
- Upgrading to a compatible new model
Special Considerations for WCN in Combi Boilers
Combination boilers like the Elite Ultra 150WCN require precise configuration. Their WCN ensures proper integration of space heating and domestic hot water functions, which is why professional installation is strongly recommended.
