To install a Black and Decker electric tankless water heater, follow the manufacturer’s instructions, ensuring proper electrical connections and plumbing setup for optimal performance.
Installing a Black and Decker electric tankless water heater requires careful planning and proper electrical/plumbing connections. This guide covers everything from mounting to final testing for safe, efficient operation.
Tools and Materials Needed
Gather these essentials before starting:
- Adjustable wrench
- Pipe cutter
- Voltage tester
- Teflon tape
- Wire strippers
- 1/2″ NPT fittings
- 8 AWG copper wire (for 13kW+ models)
For electrical work, consider hiring a licensed electrician if you’re unfamiliar with high-voltage wiring.
Step-by-Step Installation Guide
1. Choose the Right Location
Select a mounting spot that meets these requirements:
- Within 50 feet of main electrical panel
- Protected from freezing temperatures
- Accessible for maintenance
- Near water supply lines
Black and Decker units like the BD-POU-13HD model need at least 6″ clearance on all sides.
2. Mount the Unit Securely
- Locate wall studs using a stud finder
- Mark mounting holes from template
- Drill pilot holes
- Secure with provided screws
Ensure the unit is level before tightening completely.
3. Connect Water Lines
Follow these plumbing steps:
- Shut off main water supply
- Install isolation valves on both sides
- Connect cold water inlet (marked blue)
- Connect hot water outlet (marked red)
- Use Teflon tape on all threaded connections
For hard water areas, consider installing a descaling system to prolong heater life.
4. Electrical Wiring
Warning: This involves high voltage (240V). Turn off power at the breaker first.
| Model | Breaker Size | Wire Gauge |
|---|---|---|
| 7kW | 2x 30A | 10 AWG |
| 13kW | 2x 60A | 6 AWG |
| 18kW | 2x 80A | 4 AWG |
Connect wires to corresponding terminals (L1, L2, Ground). Follow National Electrical Code for proper conduit installation.
5. Final Checks and Testing
- Open water supply valves slowly
- Check for leaks at all connections
- Turn on power at breaker
- Set desired temperature (typically 120°F)
- Test hot water at nearest faucet
Troubleshooting Common Issues
No Hot Water
Check these potential causes:
- Tripped breaker
- Insufficient water flow (minimum 0.5 GPM)
- Faulty flow sensor
Water Not Hot Enough
Solutions include:
- Increase temperature setting
- Check for crossed hot/cold connections
- Verify proper voltage supply
For persistent issues, consult the manufacturer’s support or a professional.
Maintenance Tips
Extend your heater’s lifespan with these practices:
- Flush annually with vinegar solution
- Inspect electrical connections yearly
- Clean inlet filter every 6 months
- Check for error codes regularly
Proper installation ensures your Black and Decker tankless water heater provides reliable, energy-efficient hot water for years to come.
