THEO UL Heater 300W

THEO UL Heater 300W  
Item #:205234
Availability:Usually ships in 2-3 business days

Provide your tank with the proper temperature with the most advanced heating technology available. THEO heaters are designed with a peculiar cylindrical shape that renders them virtually shatterproof. Fully submersible, THEO heaters function with the PTC (Positive Thermal Coefficient) heating element, a special polymer sheet silk screened with heating ink (like your car's windshield defroster), that enables them to run dry for a short time without damage. With an easy to read temperature dial, these heaters are the simplest, yet safest available.

Ideal when placed in the vertical position but can be installed in a horizontal position completely submersed.

Place in the heater in the aquarium in an area with good water circulation.

In order to set the heater, turn the knob on top of the heater, until the temperature indicator corresponds to the required temperature.

6' power cord
Rated for a 53-80 gallon aquarium

Unit is 3/4" diameter x 15.5" high.
