PLATINIUM heaters – the highest quality standard.

PLATINIUM – glass aquarium heater with thermostat which contacts covered with a layer of genuine gold. Traditional glass aquarium heaters consist of a thermostat, contacts and a heating spiral. The thermostat controls the aquarium water temperature and, if the need arises, connects or disconnects the contacts, turning the heating spiral on or off. The most sensitive elements of the circuit are the contacts – despite of using electronic support, due to metal oxidation, their surface is over time subject to gradual decay. That mechanism shortens the life span of the heater and lowers the accuracy of water heating.

In the newly presented, revolutionary AQUAEL heater - PLATINIUM – we managed to eliminate that issue. The contacts in that device are galvanically covered with a layer of genuine gold. The metal is highly chemically inert and is practically not subject to oxidization. Application of that solution significantly extended the heater life span maintaining at the same time the accuracy of its operation. It guarantees many years of failure-free operation and complete thermal safety of the animals inhabiting the aquarium. In care of the highest quality of manufacturing, each single unit is computer-tested in professional AQUAEL laboratory prior to being passed to the hands of the user. The accuracy of thermostat operation is 1ºC.

Key features are:

  • gilded contacts guarantee long life span of the device (guaranteed 2 years)
  • electronic thermorelay ensures accurate temperature
  • stepless regulation of temperature in wide range (from 18-32C)
  • each piece computer-tested
  • LED indicator on/off

This premium heater is suitable for aquariums 10-25L.

Ask a question about this product
I was thinking of this for a Fluval Edge 23L but, the room that I plan to put it in is usually only about 60/63 degrees. (except the brightest of summer days) Would that room temperature make this little heater work too hard? Do you think I should go for the 50W? Thank you for your time. :)


Not much in it but if you want a heater to last longer, make it work less. So bigger one would have more longevity.

Whys does the led one and off indicator keep going off


It goes on when it's heating the water.


When the light is on it means the heater is heating the water and when it is off the heater is practically shut off, it is just maintaining the heat rather than heating the tank up.
