What Is An Aquarium Heater?

 

An aquarium heater is a device used to warm up the water of your fish tank. To keep fish healthy and happy, it’s important to maintain a stable water temperature and to reduce temperature fluctuations. The aquarium water heater has a thermostat inside; it constantly monitors the water and will switch off once the desired temperature is reached.

Types Of Aquarium Heaters

 

Submersible Aquarium Heaters

  • Most commonly used and popular type of aquarium water heater.
  • Also called an aquarium glass heater because the heating element is usually coiled around a thin glass tube or ceramic insert.
  • Easy to set and adjust via the temperature dial at the top.
  • Good-value submersible heaters include our range of Aqua One Glass Heaters or Aqua One Thermosafe Heaters.
  • The best aquarium heater can be found amongst our range of Eheim Jager Glass Heaters.

External Inline Aquarium Heaters

  • Installed on the hose of an external canister filter or sump pump.
  • As water moves through the inline heater, the aquarium water is heated before it’s pumped back into the aquarium.
  • Consistent water temperature is easily maintained as water is always moving through the heater.
  • Check out our Hydor External Inline Heaters.

Nano Heaters

  • Designed for smaller aquariums less than 50L.
  • Ideal for nano tanks or betta fish tanks due to their compact size.
  • Usually preset to 25°C and are not adjustable.
  • Check out our range of Aqua One fish tank heaters, especially the Aqua One Nano Glass Heaters and Aqua One Nano Plastic Heaters.

Is A Heater Required For My Aquarium?

 

Whether or not you need an aquarium heater depends on what type of fish you keep. If you have tropical or marine fish, then the water in your fish tank needs to be warmer than if you keep coldwater fish like goldfish or bettas. Even so, it’s recommended to have a heater running during cooler months to keep coldwater fish active and happy.

Choosing The Right Heater For Your Tank

 

As a general rule, we recommend 1 watt per 1 litre of water. To run the most efficient aquarium heater, it is better to round up to the larger size when calculating which heater to buy. This is because a larger heater will heat up the water faster and stay switched off for longer. A heater that is too small, or not powerful enough for your tank, may cost more to operate in the long run.

Please also check the manufacturer’s recommendations when choosing a heater. For example, Aqua One recommends their 300 watt aquarium heater for a 300L tank.

However, as their heaters are larger and more efficient, Eheim recommends their 300 watt aquarium heater for tanks between 600L–1000L.

Where Should I Place My Aquarium Heater?

 

Submersible fish tank heaters are best placed near the output of the filter so heat can be evenly dispersed throughout the tank. Position an aquarium thermometer on the opposite end of the tank so you can monitor the temperature of the aquarium.

Place aquarium heaters at a 45-degree angle to prevent them from switching off prematurely. If a heater is set in an upright position, the thermostat, located at the top of the heater, could be accidentally triggered by the ambient heat rising directly from the heating element.

How Long Does It Take For An Aquarium Heater To Heat Up Water?

 

It usually takes around half an hour for an aquarium heater to heat up the water in a fish tank. This will depend on the current temperature of the water, how strong the aquarium water heater is, and the size of your tank. It may take up to a couple of hours to heat up larger tanks.
