Tetra HT Submersible Aquarium Heater

Free Shipping at $75

Tetra HT-Series Submersible Heaters are created especially for ease of use in your aquarium. An electronic thermostat automatically adjusts the heat output to keep the water at a constant 78°F - all you have to do is put it in the aquarium and plug it in!

  • Easy to control with no adjustment required
  • Fully submersible & shock resistant
  • Maintains constant healthy water temperature


An electronic thermostat automatically maintains water temperature at 78° +/- 2° F (25° +/-  1° C) and prevents overheating to extend the life of the heater. No adjustments are necessary.

The indicator light lets you know when the water is being heated (red light) and when it is at the proper temperature (green light). Silicon Carbide crystals improve heat distribution and transfer. The strong glass tube is heat and shock resistant.

2-year manufacturer warranty.
