• Enjoy limitless hot water for showers, washing dishes, and laundry, preventing the frustration of running out during peak usage times.
• Experience consistent water temperature without fluctuations since tankless systems respond quickly to demand changes, providing hot water instantly.
• Increase comfort in your daily routine, allowing multiple outlets to run simultaneously without affecting performance.

Installation Process

Installing a tankless electric water heater involves specific tools and a step-by-step approach for a successful setup. Follow the guidelines below to ensure a smooth installation.

Required Tools And Materials

• Adjustable Wrench: For tightening connections and securing fittings.
• Screwdriver Set: A variety of screwdrivers, including Phillips and flathead, are necessary for mounting brackets and covers.
• Hose: Use a hose for draining the old water heater if applicable.
• Pipe Insulation: Helps maintain the water temperature and increases energy efficiency.
• Teflon Tape: Seals threaded plumbing connections to prevent leaks.
• Voltage Tester: Ensures the power is off before starting the installation.
• Safety Gear: Includes gloves and safety goggles for personal protection during installation.

1. Cut Off the Power And Water Supply: Turn off the circuit breaker controlling the old water heater and shut off the main water supply valve. This prevents potential water flow or electrical accidents during installation.
2. Drain The Old Water Heater: If replacing an old tank-style water heater, connect a hose to the drain valve and direct the water to a suitable drainage area. Ensure the tank is entirely drained.
3. Choose The Right Location: Select a location that is easily accessible, allows for proper ventilation, and avoids areas where liquids could drip on the unit. Mount the unit securely on a wall or another sturdy surface.
4. Install A Dedicated Circuit: Depending on your model's requirements, install a dedicated circuit to provide adequate power. Check the specification for the appropriate amperage.
5. Connect Water Lines: Use the appropriate fittings to connect the cold water supply line to the inlet valve and the hot water line to the outlet valve. Apply Teflon tape on threaded connections to ensure a proper seal.
6. Test For Leaks: Open the water supply valve and check for leaks around the connections. Tighten any loose fittings as necessary.
7. Power Up The Heater: Once connections are secure and there are no leaks, restore power at the circuit breaker. Follow the manufacturer’s instructions to set any desired temperatures or configurations.
8. Insulate Pipes: Apply pipe insulation on the hot water pipes to help maintain the temperature and reduce energy loss.
9. Perform A Final Check: Review all connections, settings, and make adjustments as necessary. Ensure proper ventilation is in place.

Following this comprehensive guide ensures a safe and efficient installation process for your tankless electric water heater, maximizing its benefits for your home.

Factors To Consider Before Installation

When installing a tankless electric water heater, consider various factors to ensure efficiency and compliance with regulations. The following points detail essential aspects of the installation process.

Location

• Choose an accessible location to facilitate maintenance and ensure proper ventilation. Avoid mounting on exterior walls in colder climates to decrease the risk of freezing.
• Ensure the unit mounts securely on a sturdy wall or surface for stability, which optimizes performance and safety.

Local Codes and Regulations

• Check local and national electrical codes before installation. Compliance with standards, such as the National Electrical Code NFPA 70 (USA) or CSA C22.1 (Canada), is crucial for safety and legality.

Safety Precautions

• Turn off the power supply to the existing water heater at the circuit breaker or fuse box. Also, shut off the water supply valve to prevent leaks during installation.

Sizing The Unit

• Determine the appropriate size for your tankless electric water heater based on your household's hot water demand. Calculate the flow rate in gallons per minute (GPM) needed for simultaneous fixtures and activities, such as showers, dishwashing, and laundry.
• Refer to manufacturer specifications to match the heater's capacity with your peak flow rate. Choosing an undersized unit may lead to insufficient hot water during high-demand periods.

• Assess your home's electrical system to ensure compatibility with the tankless electric water heater. Consider the unit's wattage and voltage requirements, typically ranging from 240 volts to 36 kilowatts.
• Install a dedicated circuit to provide sufficient power while minimizing the risk of tripped breakers. Ensure proper wire gauge and circuit protection, following local electrical codes.

Common Issues And Troubleshooting

Tankless electric water heaters may encounter specific problems. Identifying these issues early allows for effective troubleshooting and ensures optimal performance.

Error Codes

Error codes indicate specific issues with your tankless electric water heater. Refer to the manufacturer's manual for the exact meanings of error codes. Common error codes include:

1. E1: Indicates a water temperature sensor problem. Check connections and replace the sensor if necessary.
2. E2: Relates to a flow sensor error. Ensure the water flow is adequate and inspect for obstructions in the inlet filter.
3. E3: Signifies overheating. Verify that the heater is not set to a temperature above recommended levels and check for proper ventilation.
4. E4: Denotes an electrical fault. Inspect electrical connections and ensure compatibility with your system's voltage.

Regular Maintenance Tips

Regular maintenance prevents many common issues with tankless electric water heaters. Follow these tips for effective upkeep:

1. Flush the System Annually: Remove mineral buildup by flushing the system with a vinegar solution. This maintains optimal heating efficiency and extends the unit's lifespan.
2. Inspect Inlet Filters: Clean or replace inlet filters every six months. This prevents debris from clogging the water flow.
3. Test the Pressure Relief Valve: Check the valve quarterly to ensure it operates correctly. This helps avoid pressure buildup in the system.
4. Check Connections: Inspect electrical and plumbing connections for wear or leaks. Tightening loose connections or replacing damaged components prevents potential failures.
5. Monitor Temperature Settings: Keep the output temperature between 120°F and 140°F. This provides adequate comfort and reduces the risk of scalding.

Adhering to these troubleshooting steps and maintenance guidelines helps ensure your tankless electric water heater operates efficiently and reliably.
