What we liked

  • + The listing says it sticks permanently to glass and works as a 24-hour heat source, with no lamp or bulb to replace.
  • + It is listed as UL/cUL approved and usable with a thermostat, which is how any under tank heater should be run.
  • + A pack of 2 covers two small tanks or a spare, and the 10 to 20 gallon rating fills the size gap in this guide.

Trade-offs

  • - It costs more than the 4 watt single pad it replaces because the price is for two heaters, so check you need both.
  • - Heat from below only warms the floor, so it will not give an overhead basking spot or air warmth for the whole enclosure.
