Aquael Platinium 25W Aquarium Heater – Electronic Thermostat

Aquael Platinium 25W Aquarium Heater is a premium adjustable glass heater designed to provide accurate, reliable temperature control in small freshwater and marine aquariums. Featuring a fully electronic thermostat, convenient One Touch temperature adjustment and easy-to-read LED indicators, it makes maintaining a stable aquarium temperature simple.

Designed for aquariums of approximately 10–25 litres, the Aquael Platinium 25W is an excellent choice for suitably sized nano aquariums, small tropical fish tanks and planted aquarium setups requiring controlled heating.

Unlike traditional heaters that rely on mechanical thermostat contacts, the Platinium uses electronic temperature control with a stated accuracy of ±0.4°C. Its built-in electronic thermometer and LED indicators allow you to check the temperature setting and monitor operation without complicated controls.

Accurate Heating for Small Aquariums

Maintaining a suitable water temperature is important for the health and comfort of tropical aquarium fish and other temperature-sensitive aquatic animals.

Rapid temperature fluctuations can cause stress, particularly in smaller aquariums where water temperature may change more quickly than in larger systems.

The Aquael Platinium 25W features a high-precision electronic thermostat designed to maintain the selected temperature accurately during normal operation.

Its stated thermostat accuracy of ±0.4°C makes it a useful option for aquarium owners who want better temperature regulation than a basic non-adjustable heater.

Important: Heater performance depends on aquarium volume, room temperature, water circulation and the temperature difference between the aquarium and its surroundings.

Simple One Touch Temperature Adjustment

The Aquael Platinium range features an intuitive One Touch control system, allowing the temperature setting to be adjusted using a single button.

The LED display provides clear temperature information, including the selected setting and the current water temperature indication.

This makes it easy to check the heater without removing it from the aquarium or adjusting a traditional mechanical dial.

For temperature-sensitive fish, always verify the actual water temperature using a separate aquarium thermometer.

Fully Electronic Thermostat

Traditional aquarium heaters commonly use mechanical contacts to switch heating on and off. These contacts can experience wear with repeated operation.

The Aquael Platinium Heater uses a fully electronic control system without conventional mechanical thermostat contacts.

This design helps reduce mechanical wear within the temperature control mechanism and allows Aquael to provide precise regulation.

The heater also incorporates an electronic temperature sensor and LED indicators to assist with monitoring.

Suitable for 10–25 Litre Aquariums

The Aquael Platinium 25W is designed for aquariums with an approximate volume of 10–25 litres under suitable operating conditions.

It may be appropriate for:

• Nano tropical aquariums: Heating smaller tanks containing fish suited to the aquarium volume.
• Small planted tanks: Maintaining appropriate temperatures for compatible aquatic plants and livestock.
• Small shrimp aquariums: Providing controlled heating when required by the species being kept.
• Freshwater aquariums: Maintaining temperatures for compatible tropical species.
• Small marine aquariums: Suitable saltwater applications where the heater capacity is appropriate.

Choose heater wattage according to the actual water volume, room temperature and required water temperature. A larger heater may be necessary if the aquarium is kept in a particularly cool environment.

How to Install the Aquael Platinium 25W Heater

1. Choose a suitable position inside the aquarium where water circulates freely.
2. Attach the supplied mounting accessories to the heater.
3. Secure the heater to the aquarium glass in accordance with the manufacturer's instructions.
4. Ensure the heater is positioned at the required water depth and remains fully covered as specified in the manual.
5. Allow the heater to adjust to the aquarium water temperature before switching it on, following the supplied instructions.
6. Connect the heater to an appropriately protected electrical outlet.
7. Use the One Touch control to select the required temperature.
8. Check the displayed temperature and verify the water temperature with a separate thermometer.

Safety: Always disconnect the heater from the power supply before removing it from the aquarium, changing the water level or performing maintenance. Follow Aquael's specified cooling and handling instructions.

Tips for Maintaining a Stable Aquarium Temperature

• Position the heater near an area of gentle water movement for more even heat distribution.
• Avoid placing the heater where decorations or plants obstruct surrounding water flow.
• Check the water temperature regularly with a separate thermometer.
• Keep the aquarium away from strong sunlight, cold draughts and sudden temperature changes.
• Ensure the heater remains correctly submerged whenever it is operating.
• Inspect the power cable, glass body and mounting accessories for damage during maintenance.
• Disconnect the heater before cleaning or handling it.

In warmer Australian weather, remember that an aquarium heater cannot cool the water. If tank temperatures rise above the required range, suitable aquarium cooling or room-temperature control may be necessary.

Choosing the Right Aquael Platinium Heater Size

Aquael produces the Platinium range in several wattages to suit different aquarium volumes.

• 25W: Approximately 10–25 litres.
• 50W: Approximately 15–50 litres.
• 75W: Approximately 35–75 litres.
• 100W: Approximately 60–100 litres.
• 150W: Approximately 90–150 litres.
• 200W: Approximately 130–200 litres.
• 250W: Approximately 180–250 litres.
• 300W: Approximately 230–300 litres.

These are manufacturer-recommended aquarium volume ranges. Actual heating requirements depend on ambient temperature, aquarium insulation and the target water temperature.
