Please be aware that an aquarium heater is designed to increase, stabilise and maintain temperature. It does not cool aquariums situated in ambient room temperatures that exceed the setting on the dial. For example, you are unlikely to achieve 22 degrees in an aquarium situated in a room with an ambient temperature of 28 degrees. It will likely be warmer or nearer to the room temperature. To decrease temperature below room temperature you will require a chiller or an aquarium fan.

Dimensions: 410(H)x23mm (Diameter) (Diameter 34mm with heater guard)
