Hydor THEO Heater Information



Part #: T11102

Make sure to keep your fish warm during the day and night with the Hydor Theo Heater from Pet Store. This is essentially a lighting fixture, which is similar in function with ordinary reptile lighting. There are some major differences between them, though. One of which is the bright color that it emits, and another is the function.

The Hydor Theo Heater can be installed with special lighting fixtures that will add a touch of realism to the day and night hours that you want to create within your fishes' controlled environment. Of course, this is especially used during the night to keep your pet comfortable, as well as to prevent them freezing in the water, especially during cold seasons. However, this is also useful to operate in the daylight hours. The heat that this product will radiate will remind your inhabitants of the warmth of the water surface during the day.

The Hydor Theo Heater is completely water-proof, and it is meant to be submerged in the water for long periods at a time, if not permanently. It is equipped with a glass cover that protects your fish from being burned when it goes near it.

With the Hydor Theo Heater, you can now complete an aquatic environment that will not only inform your fish about the day and night cycles that you've set up, but will also remind them of the conditions and temperature of its former home.

Hydor heaters, a pant load Product Review by DAVID KIPPERMAN (Posted on 2/26/14)
Rating
Unsatisfactory

Comments: If you want to have a Friday night fish fry at your house with your fish, use these heaters. After about six months they won't shut off. Result- cooked fish!!

Terrible Heater Product Review by GR MOORE (Posted on 2/26/14)
Rating
Unsatisfactory

Comments: The thermostat on this heater is off by 10+ degrees. I set it for 75 in a newly set up, empty 40 breeder only to find it at 86 and still climbing the next morning. Bumping the thermostat down to 73 shut it off. I give it a half star only because it isn't stuck on. Hydor pumps, yes. Hydor heaters, no.

Dead fish Product Review by ROBERT CAMPBELL (Posted on 2/26/14)

Unsatisfactory

Comments: After 3 weeks one of the 300 watt units on my 125 gallon saltwater tank lost control and turned itself on. Period. On. Next morning the tank was about 100 degrees. Ice saved some fish, all else died.

Complete Junk Product Review by JOEL SAXTON (Posted on 2/26/14)
Rating
Unsatisfactory

Comments: Don't waste your money on this piece of junk. It is totally inaccurate (on the order of about 10 degrees fahrenheit) as several unsatisfied customers have noted here. Hydor should be ashamed of themselves for selling second rate products which have surely destroyed many an aquarium.

Garbage Product Review by JOHN NARDUCCI (Posted on 2/26/14)
Rating
Unsatisfactory

Comments: First one I bought did not work. Hydor's response was that my thermometer was bad and not the heater. Second one worked for a little over a month and then I woke up this morning to find it went on last night and never shut off tank temp is 88 degrees farenheit. Heater was set for 79 and never shut off.
