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.
