Aquarium heater
Keep Your Water at the Perfect Temperature All Year
A dependable aquarium heater is essential to give your fish a stable temperature, day and night. At AnimalParadise, our submersible heaters and water warmers suit both freshwater and reef aquariums, ensuring lasting comfort for every inhabitant.
How many watts does my aquarium heater need?
As a rule of thumb, allow around 1 watt per litre of water in a heated room, and a little more for large or demanding tropical tanks. For a 100 litre aquarium, a 100 to 150 watt model is a solid starting point.
Glass or stainless steel heater, which is better?
Glass submersible heaters are affordable and ideal for freshwater, while stainless steel models resist knocks and suit reef setups. Always choose a heater with overheat protection that shuts off when exposed to air.
Our range of aquarium heaters
- Submersible heaters : Discreet and effective, they clip to the glass and warm the water continuously.
- Stainless steel models : Tough and long lasting, they withstand saltwater and frequent handling.
- Overheat protection : An automatic cut-off safeguards your fish if the water level drops too low.
The AnimalParadise expert tip: Always position the heater near a flow of water so the warmth spreads evenly, and wait a few minutes before unplugging it during a water change.
