WCN on a water heater refers to the Water Connection Number, indicating the specific plumbing connections for efficient installation and maintenance.
If you’ve noticed “WCN” on your water heater’s model number or documentation, you’re likely wondering what it means. WCN stands for “Water Control Number,” a manufacturer-specific identifier used in model numbers for certain water heaters and boilers.
Understanding WCN in Water Heater Model Numbers
The WCN designation appears primarily in model numbers for high-efficiency combination boilers and water heaters. For example, the HTP Elite Ultra ELU-150WCN uses this designation in its model number.
How Manufacturers Use WCN Codes
Water heater manufacturers use WCN codes to:
- Identify specific product configurations
- Track warranty information
- Determine replacement parts compatibility
- Manage service requests
WCN and Water Heater Warranties
The WCN plays an important role in warranty claims. As noted by U.S. Water Heating Solutions, manufacturers use these identifiers when processing warranty claims. You’ll typically need the complete model number (including WCN) when:
- Registering your water heater
- Requesting warranty service
- Ordering replacement parts
Warranty Claim Process with WCN
- Contact manufacturer with your WCN-containing model number
- Receive warranty authorization number
- Schedule service with approved provider
Finding Your Water Heater’s WCN
Locate your WCN by checking:
| Location | What to Look For |
|---|---|
| Manufacturer’s label | Model number on unit’s side |
| Installation manual | First few pages |
| Purchase documentation | Receipt or invoice |
Common Manufacturers Using WCN
These brands frequently use WCN in model numbers:
- HTP (High Temperature Products)
- Bradford White
- A.O. Smith
WCN vs Other Water Heater Codes
While WCN identifies water control systems, other codes serve different purposes:
Common Water Heater Model Number Components
- WCN: Water Control Number
- BTU: Heating capacity
- GAL: Tank capacity
- V: Voltage requirements
For example, when looking at water heater thermostat controls, you’ll notice they’re matched to specific model numbers that may include WCN designations.
Importance of WCN for Repairs
Service technicians use the WCN to:
- Identify correct replacement parts
- Access technical specifications
- Verify warranty coverage
- Determine compatible accessories
If you need specialized tools for water heater maintenance, the WCN helps ensure you get the right equipment for your specific model.
Example of WCN in Action
A customer with an ELU-150WCN boiler needs a new heat exchanger. The WCN helps the technician quickly identify the exact replacement part rather than guessing based on general specifications.
Special Considerations for WCN Models
Water heaters with WCN designations often have unique features:
Common Features of WCN Models
- High-efficiency heat exchangers
- Advanced control systems
- Modulating burners
- Combination heating/hot water systems
These features often require professional installation and maintenance, making the WCN particularly important for service records.
