Comfort Zone Golds are glass aquarium heater with with gold plated thermostats.

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 Aquael Comfort Zone Gold heaters 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 oxidisation. 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 1°C.

  • gilded contacts guarantee long life span of the device
  • electronic thermorelay ensures accurate temperature
  • stepless regulation of temperature in wide range
  • durable openwork housing made of plastic
  • does not cause burns in fish
  • resistant to mechanical damage
  • each specimen undergoes computer-assisted testing
