Aqua El NeoHeater

An electronic heater with the capability of regulating the temperature
It is flat shaped plastic and comes with an exceptionally accurate thermostat.
It delivers a new way of programming and a system of constant control of current and set temperature.
It is flat shaped plastic and comes with an exceptionally accurate thermostat.
It delivers a new way of programming and a system of constant control of current and set temperature.
- Microprocessor thermostat
- Built-in electronic thermometer (17-36 deg C)
- Light signalling of surpassing the set temperature
- Convenient temperature adjustment (‘one-touch’ system)
- Wide range of temperatures up to 36ºC
- Modern, exceptionally flat shape : unbreakable!
- Possibility of installing on any aquarium wall
- Thermal safety switch
- Fully waterproof (IP68 standard)
- Supplied with mounting bracket and suction cups
Aqua El NeoHeater is the first shatterproof aquarium heater on the market that comes with an accurate thermoregulator based solely on electronic sub-assemblies.
It is flat and comes with a double, universal bracket that allows it to be installed on any wall in the aquarium.
A circle made of LEDs is visible on the front of the heater.
Its operation is exceptionally simple and can be performed using only one button placed on the heater top.
After connecting it to the power supply it is enough to set the desired temperature by pressing the button. The temperature will be indicated by lighting a LED. After a while lighting of all diodes confirms the setting of a new temperature. Except for the diode indicating the temperature desired in the aquarium, another one will be lit as well - indicating current water temperature. If it is lower than the set temperature, the LED will blink slowly showing that the heater is operating. On the other hand if the water temperature in the tank is higher than the one set (e.g. during heat waves), the LED indicating it will blink very quickly to warn of the possibility of overheating the aquarium water.
Therefore, in addition to the heater, we receive a modern, electronic thermometer.
Additionally they are equipped with a thermal switch that protects the device from overheating in case of leaving it out of the water.
Their usage is not restricted to aquariums - thanks to very durable construction they can be used in aquariums, pools etc with turtles and other reptiles.
