Frequently Asked Questions

Q: Is the 3000W instant electric water heater suitable for a full shower?

A: This instant electric water heater works well for light showering, especially in warmer months. It is not recommended as the sole shower heating source in cold climates or winter conditions, as the 3000W output is best suited for washing tasks like hand-washing, dish-washing, and warm-season bathing.

Q: Can I use this water heater with both 110V and 220V power supplies?

A: Yes — the unit supports both 110V and 220V AC power supplies, making it adaptable for use in different regions and electrical setups. Always confirm your local voltage before installation and ensure your wiring meets the minimum 2.5 mm² requirement with a circuit breaker rated above C32.

Q: How do I control the water temperature on this instant heater?

A: Temperature is regulated by adjusting the water flow rate. A higher flow rate produces cooler water, while a lower flow rate produces warmer water, within the 20–50°C operating range. The built-in digital display shows the current water temperature in real time.

Q: What should I do if the display shows an error code?

A: The unit features a built-in error code system. E1 indicates over-temperature — switch off power and run cold water through the unit before restarting. E2 points to heating tube failure requiring tube replacement. E4/E5 indicate a temperature sensor issue — power off, run cold water, then restart. A spinning display with no temperature reading means insufficient water pressure or no water flow detected.
