KW Zone Dophin Spiral Core Heater – 50W

The KW Zone Dophin Spiral Core Heater – 50W is a 50W fully submersible aquarium heater with a spiral heating element inside a glass tube and an adjustable thermostat at the top. It keeps tropical aquarium water at a stable temperature, switching on and off automatically to hold the setting you choose.

Key features

• 50W output — as a rough guide, suits tanks of about 50 litres
• Adjustable thermostat dial to set your target temperature
• Spiral heating core inside a glass tube for even heat
• Fully submersible design for aquarium use

Installation & use

Choose a heater size to suit your tank — a common rule of thumb is roughly 1 watt per litre of water. Mount it at an angle in an area of good water flow, making sure it sits at or below the minimum water line, then let it rest in the water for 15–20 minutes before plugging in so the glass can adjust to the water temperature. Set the thermostat and check with a separate thermometer.

Safety

Always unplug the heater before putting your hands in the water, doing water changes or removing it, and let it cool for a few minutes before taking it out of the tank. Never run it out of water, and check it regularly for cracks or damage.
