Product description

ULTRA HEATER – The first smart aquarium heaters.
New in 2020 – Smart Heating System*. A microprocessor controller selects the lowest heating power necessary for maintaining the set water temperature in the aquarium. When necessary, the microprocessor increases or decreases the power to maintain the set temperature. Using the Smart Heating System allows for lower temperature amplitude of aquarium water thanks to the more stable operation of the device. In addition, the SHS positively affects the durability of the heating element and the heater’s lifespan.
The heater is programmed using a very convenient ONE-TOUCH system featuring a single button and an LED ring indicating current and set temperatures.
The electronic thermostat offers unique precision of +/-0.25°C, maintaining constant temperature in the aquarium, ensuring thermal comfort for even the most sensitive aquarium species.
Temperature control range from 20 do 33°C makes it possible to use the heater in the treatment of many fish diseases, including the so-called “fish smallpox”.
ULTRA HEATER features also a built-in warning system in case of water overheating in hot weather. Shatterproof plastic housing makes the ULTRA HEATER water heaters perfect for tanks with large, strong fish and even with water turtles. The devices are completely safe and will not cause burns to even such sensitive fish as catfish and rays.
The ULTRA HEATER range encompasses 6 models ranging from 25 to 200 W, and are available in 3 lengths, which allows precise adjustment to aquarium size.
ULTRA HEATER devices are the most advanced products on the market intended for heating water in aquariums.
Heating aquarium water has never been so intuitive and safe. See for yourself!
