Treating your tropical or marine fish to one of these heaters means the lucky things get to take advantage of our in-depth aquarium heater experience and knowledge. And you get to relax at the thought of the 2-year guarantee and excellent safety credentials. These heaters are super-reliable, and thanks to the extra-thick safety glass and plastic end cap, are also extra safe. The positive click-control makes its easy to adjust the temperature precisely, but as the heater is already set to 24c you might not find you need to.

Easily adjustable for simple operation

Extra-safe shatter resistant glass

Easy-to-check on/off light for peace of mind
