They are usually placed at an angle so that a lower water level won't cause them to break. If a heater is functioning under water and then taken out of the water, it will usually break because of the sudden temperature change. These heaters are also usually placed under the filter output so that the water entering the tank is heated just as it enters the aquarium.
This helps to evenly heat the tank. Hanging heaters hang over the side of the aquarium like a filter , although the heating tube is inside the aquarium. The temperature dial usually sits right on the hanging part. As with the heaters above, you will have to make sure the water level never drops down to the glass part of the heater, it might break! The water usually comes through the filtration and is on its way back to the main tank when it passes through the "in-line" heater, where it is heated to the appropriate temperature before it gets back to the aquarium.
This type of heater is great if you have aggressive fish that may damage an internal heater. In-line heaters are also more accurate, insuring your temperature does not fluctuate. Most heaters include suction cups to keep them against the side of the aquarium. The temperature dials vary greatly on all models. The heater is watt thoughi hope it will be okay. It has a temp dial I havent been able to find an inline heater with low wattage. It is common to use heaters rated for much larger tanks that you own.
For example if the heater heats water, returns it to the tank right by the canister filters intake and this warmed water is then pulled back into the filter. Simply put the system would heat water, return it but then pull in and reheat the same water mixed with new water. This may leave your tank a bit below your desired temperature.

Keep these tips in mind when deciding what aquarium heater size you need: Small aquariums can be heated much quicker and should avoid oversized heaters. Large aquarium heaters may not work as well as two smaller heaters. This is highly dependent on water circulation.
Either choose two smaller heaters or direct strong currents towards your heater for the best results. Always keep a back up heater! Even if your back up is a cheaper model it can still save your fish while you get a longer lasting model. Hey Mike, This is an interesting one. What I would do really depends on a few things.
However, they can be broadly categorized into two main types of heaters, in-tank heaters and in-line heaters. An in-tank heater is placed inside an aquarium. These are the most common type of aquarium heaters.
There are three main types of in-tank filters which are submersible heaters, immersible heaters, and pad heaters. Submersible heaters are the most popular type heaters used in aquariums today. As the name indicates, this heater is placed inside the aquarium, fully under water.
These heaters are efficient and reliable. They are often made out of glass material, and they are attached to a suction cup. This allows the heater to be placed on the side of the aquarium wall.
The heater can be positioned near a filter intake or output, in order to make sure that the heated water is circulated throughout the aquarium.
For efficiency, it can be positioned horizontally near the bottom of the tank. Since warm water rise to the top, this is a good way to make sure that the entire tank is heated.
This strategy should be used especially for taller tanks. If you do place the heater near the bottom of the tank, make sure you leave some space between the heater and the gravel layer. The Aqueon Adjustable Pro Aquarium Heater is our top recommendation for most aquariums due to the durable design and safety feature.
This is a good choice because it is an aquarium heater with a protective guard already built in. However, Aqueon offers a budget friendly option as well. The Aqueon Glass Heater does not have the plastic housing on the heater, but it is made of shatter resistant glass. While less expensive, this model also has a built-in auto shut off function that prevents the heater from overheating.
Immersible heaters function similarly to submersible heaters, except they can not be fully submerged under water. They are hanged from the edge of the aquarium wall. They are less versatile in terms of their positioning.
They also tend to cost less than submersible heaters. While they were more common in the past, they are becoming less common as they are being replaced by fully submersible heaters. Both submersible heaters and immersible heaters are often manufactured with glass.
Therefore, it is important to handle them with care. Invest in a heater made with shatterproof or impact resistant glass. Covering the heater with an aquarium heater guard may be a good idea as well. Pad heaters, or mini aquarium heaters, are installed on the bottom of the aquarium floor.
These are generally small aquarium heaters designed for smaller aquariums such as betta tanks. Most of these heaters, such as the Hydor Slim Heater have preset temperatures so the temperature can not be adjusted.
They are easy to operate, and they can work well for small aquariums and bowls. They are connected by a tube line, which can be connected to a filtration system. They can be installed with only a pump, without a filtration system as well. One advantage of an in-line aquarium heater is the visual appeal. It is not installed inside the aquarium, so it can be placed out of sight. Another advantage of an in-line aquarium heater is the ability to maintain a constant temperature throughout the aquarium.
Some in-tank heaters have issues maintaining a constant temperature throughout the aquarium, especially when it is not placed in an area with good water flow. An in-tank heater may heat up one side of an aquarium and shut off, while leaving the other side of the tank under-heated. An in-line aquarium heater will avoid this issue by having the heating mechanism right where the water is being pushed. Where should an aquarium heater be placed? If you are installing an in-tank heater, it should be placed where there is good water flow.
Placing the heater near a filter intake or output would be a good idea. This will allow the heated water to circulate throughout the tank. If the heated water remains stagnant around the area of the heater, the thermostat on the heater may turn off the heating mechanism before the entire tank is heated.
If you have a tall aquarium that has a narrow shape, place the heater near the bottom of the tank since warm water will rise to the top. If the heater is placed near the surface of the tank, the warm water may not have a chance to circulate all the way to the bottom of the tank. Of course, placing the heater at the bottom is only possible with a fully submersible aquarium heater. How does an aquarium heater work? The thermostat, or the aquarium heater controller, is the component that senses and maintains the water temperature.
When the water temperature drops to a certain level, the thermostat will trigger the heating mechanism. When the water temperature reaches a certain level, the thermostat will shut off the heating mechanism. Small aquarium heaters such as pad heaters and bowl heaters may not have a thermostat. They may also have a thermostat that is present to a certain range of temperature that is applicable for most tropical fish. Keep in mind that their temperature may not be adjustable. In addition, they are typically designed for smaller aquariums, so they will take much longer to heat up a tank.
