Product Information

Tetra HT Aquarium Heaters offer high performance aquarium heating for a range of tank sizes.

Using the latest aquarium heating technology these submersible heaters include an easy-to-set temperature scale that takes the effort out of simply taking a temperature reading and boast a double ceramic element to guarantee the steady conduction of heat through the glass heater.

For additional safety there is an extra thick heat and shock resistant glass tube that surrounds the heater core and to make it clear when the heater is in operation each heater has a clear indicator light.

It includes an extra-long mains cable, connecting to an electronic regulator to ensure that the correct temperature is always maintained within the tank and as an additional safety feature is a built-in power shut-off for if the aquarium ever runs dry.

Key Features:

  • New safety power cut off
  • Double ceramic element
  • Easy to read and set temperature scale
  • Extra long cable for convenient use
  • Fully submersible
  • Heavy-duty suckers for attachment to tank

    This took 24hrs to Heat a freshly filled 90L aquascape from 12oC to 25oC. It works, but in reality I wish I had brought a 150 or 200 model. I'd go x1.5 to x2.0 the manufacturers size.
