KW Zone Dophin Spiral Core Aquarium Heater - 25 W

The KW Zone Dophin Spiral Core Heater is a submersible thermostatic aquarium heater for freshwater and marine tanks, in six wattages from 25 W to 300 W.

Key Features

• Submersible heater with built-in thermostat
• 25, 50, 100, 150, 200 and 300 W
• For freshwater and marine aquariums

Choosing A Size

• A common guide is about 1 W per litre in a room kept at normal temperature.
• In air-conditioned UAE homes the room is often warm enough that small tanks need little heating — a thermometer tells you.

Available in: 25, 50, 100, 150, 200 and 300 W

Good To Know

• Unplug the heater and let it cool for 15 minutes before taking it out of the water — a hot heater can crack.
• Let a new heater sit in the tank for 30 minutes before switching on so the glass reaches water temperature.
• Mount it where water flows past, away from gravel.
• Leave a drip loop in every power cable, so water running down the cord drips off before it reaches the socket.
• Plug aquarium equipment into a socket protected by an RCD (earth-leakage breaker).
