THEO UL Heater 400W (Hydor)

THEO UL Heater 400W (Hydor)  
Item #:205220
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 carís 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.

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.

This heater is highly accurate due to the use of precise micro-switch technology. For saltwater or freshwater aquariums. UL listed; 6' power cord; shatterproof glass which, while not unbreakable, is designed to resist breakage in most normal aquarium situations.

Ideal when placed in the vertical position but can be installed in a horizontal position completely submersed. Good for aquariums between 80 to 105 gallons.

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

Heater has a 2 year warranty against defects in materials and workmanship.
