3.2 Electrical Requirements
The Senville 13KW model requires a 240V electrical supply. Refer to the specifications table for detailed electrical parameters.
- Voltage: 240 Volts
- Wattage: 13000 Watts
- Max. Amp Load: 1 x 54.1 A
- Recommended Minimal Wire Size: 1 x 6 AWG copper wire
- Recommended Circuit Breaker: 1 x 60 A double-pole breaker
Ensure your electrical panel has sufficient capacity and that the wiring run is appropriate for the distance to avoid voltage drop. Consult a qualified electrician for proper sizing and installation.
3.3 Plumbing Requirements
- Water Connection: 1/2" NPT
- Min. Permissible Pressure: 30 psi / 2.07 bar / 0.207 MPa
- Max. Permissible Pressure: 150 psi / 10.34 bar / 1.034 MPa
- Min. Water Flow to Activate Unit: 0.3 GPM (1.2 L/min)
It is recommended to install a tankless water heater bypass valve/isolator kit for easier future maintenance and descaling.
3.4 Flow Rate and Capacity Guide
The performance of your tankless water heater depends on the incoming water temperature and desired flow rate. Use the guide below to determine the appropriate flow for your area and needs.
Image 3.2: This selection guide helps determine the appropriate flow rate based on your geographical location's inlet water temperature and the desired outlet temperature.
To use the guide:
- Find your location on the map to determine the average inlet water temperature.
- Check the advised flow rate (GPM) at your desired outlet water temperature (e.g., 108°F).
- Calculate the fixtures that may run simultaneously to ensure your unit can meet the demand. For the 13KW model, typical flow rates for fixtures are: Bathroom Faucet (0.5 GPM), Kitchen Sink (1-1.5 GPM), Shower Head (1.5-2 GPM), Laundry (1-1.5 GPM), Dishwasher (1-2 GPM).
4. Operating Instructions
The Senville 13KW Tankless Water Heater features a user-friendly digital display for temperature control.
4.1 Powering On/Off
Press the power button (U) on the control panel to turn the unit on or off. The digital display will illuminate when the unit is active.
4.2 Setting Water Temperature
Use the '+' and '-' buttons on the control panel to adjust the desired water temperature. The display will show the set temperature. The unit's self-modulating technology will automatically adjust power levels to maintain this temperature as water flows through.
4.3 Flow Rate Indication
The digital display may also show the current flow rate (L/min or GPM) when hot water is being drawn, providing real-time operational feedback.
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your tankless water heater.
5.1 Descaling and Flushing
Over time, mineral deposits (scale) can build up inside the water heater, reducing efficiency. It is recommended to descale and flush the unit annually, or more frequently in areas with hard water.
- Bypass Kit: If not already installed, consider purchasing and installing a tankless water heater bypass valve/isolator kit. This kit simplifies the flushing process by allowing you to isolate the unit and circulate a descaling solution without affecting your home's plumbing.
- Flushing Procedure: A flushing kit, typically consisting of a pump and a bucket, is used to circulate an acid solution (e.g., white vinegar or a commercial descaling agent) through the water heater. Follow the instructions provided with your flushing kit and descaling solution.
5.2 General Inspection
Periodically inspect the unit for any visible leaks, corrosion, or damage to the electrical connections. Address any issues promptly.
6. Troubleshooting
This section provides solutions to common issues you might encounter.
6.1 No Hot Water
- Check Power: Ensure the unit is powered on and the circuit breaker has not tripped.
- Water Flow: Verify that the minimum water flow rate (0.3 GPM) is met. If flow is too low, the unit may not activate.
- Inlet Temperature: In very cold climates, if the inlet water temperature is extremely low, the unit may struggle to reach the desired temperature at high flow rates. Reduce flow or adjust temperature setting.
- Scale Buildup: Significant scale buildup can restrict water flow and heating efficiency. Perform descaling maintenance.
- Error Codes: Check the digital display for any error codes and consult the full product manual (if available) for their meaning.
6.2 Inconsistent Water Temperature
- Fluctuating Flow: Ensure consistent water flow from the fixture. Rapid changes in flow can affect temperature.
- Multiple Fixtures: If multiple hot water fixtures are running simultaneously, the unit may be exceeding its capacity. Reduce the number of active fixtures.
- Scale Buildup: As with no hot water, scale can cause inconsistent heating.
6.3 Leaks
- Check Connections: Inspect all water inlet and outlet connections for tightness.
- Internal Leak: If leaks persist or appear to be internal, immediately turn off the water supply and electrical power to the unit and contact a qualified technician.
For issues not covered here, or if troubleshooting steps do not resolve the problem, contact Senville customer support or a qualified professional.
