The Flow Heater is equipped with electronic temperature sensors to protect the tank from overheating. When they detect the cessation of water flow – they automatically turn off the device. The heaters are manufactured in accordance with strict European safety standards, which ensures safe operation and maintenance. Each device is tested and calibrated in the Aquael laboratory. A very convenient solution is to indicate by the LED display the water temperature in the tank programmed by the aquarist and the current temperature. Flow Heater operates with an accuracy of ± 0.9 °F [0.5 °C] in the range from 68 to 91 °F [20 to 33 °C]. It is easy to use thanks to the One Touch system, which allows you to change the operating temperature with the touch of a button.
