Product Features

This Mini tankless electric water heater differs from conventional storage-type mini water heaters. It doesn’t store hot water. Instead, water is heated instantaneously as it flows through the unit. A flow switch activates the powerful heating elements as water is drawn from a hot faucet connected to the appliance.

Due to the absence of standby loss, the mini heater is more energy efficient than storage-type water heaters. In addition, the unit is equipped with multiple safety devices and will continuously supply hot water as long as the faucet is open.

1. Besides, the unit has the following features.
2. Tankless, instantaneous heating for on-demand hot water, no pre-heating.Nostand-by heating loss. Energy-saving.
3. High-strength ABS splash-proof casing, UL RECOGNIZED heating element.
4. Compact appearance and unlimited supply of hot water.
5. Easy installation: The heater can be installed above or under the sink. Easy operation: The heater provides hot water at a constant temperature.
6. Micro-computer control, adopting patent heating technology. Multiple layers of composite nano-insulation material completely separate water from electricity.
7. Over-temperature protection: When the outlet water temperature reaches or exceeds 75 °C, the appliance will avoid getting scalded and start working automatically while the temperature drops to a specific temperature.
