The Ultratherm Undertank Heater (UTH)- 11″x17″model uses only 22 watts. Ultratherm Vivarium Heaters have been manufactured in Scotland for over 20 years to exacting European Standards. UL Listed component.

These are the higher quality, more durable fiberglass element models, NOT the printed version!

These pads can often be used WITHOUT a thermostat due to their low wattage density. The element is similar to the Flexwatt heat tape but it is a far more durable, longer lasting material and is sealed in a polyurethane.

The low wattage density of this product means in most cases it will maintain “reptile friendly” temps below 95 degrees. This can vary with the room temps so if precise control of temperature is needed these pads can also be used with a thermostat/rheostat.

Ideal for users with only one or a few vivariums to heat. Also works well with plastic storage bins.  For larger applications you may want to consider heat tape.
