Zoo Med Reptitherm® Under Tank Heaters

The Repti-Therm® line of under tank heaters are designed to heat the ambient (inside) air temperature of your terrarium a minimum of 5-10 degrees warmer than room temperature.

Repti-therm® Under Tank Heaters are the most economical way to heat your terrarium to safe levels. These heaters range from 4 to 24 watts, and cost only pennies a day to operate.

  • All heaters use a solid state nichrome heating element with a U.L./C.S.A. approved power cord attached.
  • Heater developed from aerospace technology. The same type of heaters are used to prevent fighter jet fuel tanks from freezing.
  • A special glue adhesive attaches the under tank heater to the terrarium, forming a solid bond for better heat transfer.
