Wattage means input. In general we can say that the higher input, the higher output. A 200 watt heater will heat a 100 litres (26.42 US gallons, 22.00 Imperial gallons) aquarium much faster than a 50 watt heater. Use our , enter your fish tank's dimensions and see what's recommended wattage for your aquarium.
50 watts of heater in a 10 gallon was the minimum that would keep them warm. Some of these tanks I had to wrap in a thick towel at night. I did not have overheating problems. I know it can happen. All my heater failures were fail-off. They would not come on. I've had many different heaters in my 32 years of tanks. The best heaters were made by Supreme believe it or not. I've had failures on all brands though. Most were fail on. And since I had 2 heaters going nothing fried. The ones that failed off were usually the heater element. Back then you could by replacement elements. Again, since I had 2 heaters instead of just one nothing ever got cold enough to cause any long lasting damage to the fish.

50 Watts (Tank Size: 10 to 16 Gallon) Adjustable Aquarium Heater Anti-explosion Submersible Fish Tank Water/ Temperature Range 18~33'c (65°f and 93°f.)Generally speaking larger aquariums need more powerful heaters. The smallest aquariums on the market need only some 25 watt heater, but a 300 liter (79.25 US gallons, 65.99 Imperial gallons) tank requires 300 watt or more powerful instead. The size of a fish tank heater does matter and it is also important to understand following: Even a 50 watt heater can heat a 300 liter (79.25 US gallons, 65.99 Imperial gallons) aquarium to a certain level, but the speed how the desired temperature is achieved is very questionable.As the gold starts to set in, my fish room is cooling as well. I was still short one heater for a 5 gallon guppy tank, so I ordered another Tetra HT10 submersible 50 Watt Heater. I like the simplicity of these heaters.
Tetra HT10 on Amazon: The above shows that manufacturers recommend 2~5 watts for each gallon of water. One thing I have noticed though, is that lack of wattage can be compensated by good water current in the fish tank to a certain point. Once after I had replaced my with a in my 40 gallon aquarium (because the Jager was too bright for my aquarium’s black background), the water temperature was stable because of the good water flow. The only difference is that the 50W heater has to stay on for a longer period of time than the 100w.
