This is the Tetra HT Submersible Aquarium Heater. You can identify it by its tall design and metallic center. It is one of the most reliable heaters on the market, providing the four things you need in a fish tank heater: Readability, versatility, safety, and ease of use.

The Tetra HT Submersible Aquarium Heater has a highly sensitive aluminum oxide core, which both helps distribute its heat as well as to detect how much heat is needed. This is a big step up from other fish tank heaters, which mostly use costly and inefficient steel.

What are its best features?

  • The big appeal of the Tetra HT Submersible Aquarium Heater is its sensitivity, but it also brings along with its safety. It shuts off automatically when not in use and can detect whether or not it is fully submerged in the water. This is important for fish tank heater safety.

What could be improved?

  • If there is a weakness in the Tetra HT Submersible Aquarium Heater, it is its size. As with any fish tank heater, its versatility of it is limited by its size. This is a medium-sized heater, meaning that it can warm most fish tanks, but that means there are some small fish tanks it will be too big to fit into.

If you are looking for a fish tank heater that can provide heat to both a large fish tank as well as a smaller habitat while also being easy to operate and read, then we recommend the Orlushy Submersible Aquarium Heater.

An easy-to-read digital display and a variety of sizes separate the Orlushy Submersible Aquarium Heater from its competitors. Never before has there been a fish tank heater with such a range of sizes while still maintaining a simple design that helps you manage your fish with ease.

Why are we impressed?

  • The variety of options this heater provides is what really sets it above the others. The larger and smaller sizes are higher priced than the others, but not many brands of fish tank heaters even come in larger and smaller sizes. This makes the Orlushy Submersible Aquarium Heater uniquely versatile.

What negatives must you be aware of?

  • The biggest issue with the Orlushy Submersible Aquarium Heater is also its greatest strength. A variety of different sizes means that you will need to know your fish and fish tank very well to know how much heat they will need. It is an easy heater to adjust but not always easy to pick a size.

The FREESEA Aquarium Heater is easy to set up and uses a fish tank heater. It can be lowered in or laid down on the bottom of your fish tank and set to a huge variety of temperatures. Once it gets the water around it to that temperature, it will turn off to keep things from overheating.

What the FREESEA Aquarium Heater provides is warmth for a huge number of different fish. Many fish that people get is the colorful tropical kind that prefers water warmer than 80 degrees Fahrenheit. But there are just as many fish that prefer water closer to 40 degrees. This heater provides for both kinds.

What stands out?

  • The best thing about the FREESEA Aquarium Heater is that exact versatility. Rarely have we found a fish tank heater that can reach both values. Combine that with the durability and ease of cleaning this heater, and the FREESEA Aquarium Heater becomes one of the longest-lasting fish tank heaters.

What cons did we manage to find?

  • There is one thing that undercuts the value of the FREESEA Aquarium Heater's range of temperatures, though: No single group of fish needs a wide range of temperatures. That means that being able to adjust the temperature in that manner will confuse some people, turning it into a drawback for some.

Uniclife Aquarium Heater

Features
  • Type: submersible
  • Tank capacity: 5-15 gallons
  • Temperature range: 68-93°F
  • Power: 50W
  • Size: 8.6 x 1 inches

More features: comes with an electronic thermostat; red rotatable knob

If you need something that is easy to read, then the Uniclife Aquarium Heater is for you. This heater goes up to 74 degrees Fahrenheit and is sold at a variety of different power levels for differently sized fish tanks. It also comes with a thermometer to place on the outside of your tank for easy reading.

The Uniclife Aquarium Heater continues the manufacturer’s trend of developing wider and wider ranges of consumer fish tank heaters. That means upping the amount of power they both receive and output. They will always work on a normal power socket, but bigger tanks take more power to heat.

What stands out?

  • There are two great things about the Uniclife Aquarium Heater. The first is the thermometer that comes with it. This makes it one of the easiest fish tank heaters to read since its thermometer is on the outside, unobstructed. The second thing is just how many different sizes of the fish tank it can heat.

What cons did we manage to find?

  • As with many specialized fish tank heaters, the biggest issue we found with the Uniclife Aquarium Heater is its complexity of it. Each model is designed to distribute its heat to a larger and larger fish tank. You have to know how big your fish tank is and what temperature you need to make use of this.

The Hitop Adjustable Aquarium Heater is a fish tank heater that sticks to the side of the inside of your fish tank by a pair of suction cups. Its temperature can be adjusted by the nob on top and red by a thermometer that is plugged into it and attached to the wall adjacent to the fish tank heater.

The great thing about the Hitop Adjustable Aquarium Heater is its ease of use. Fish tank heaters that use suction cups are great for attaching themselves to the wall of a fish tank and being easily accessed for cleaning later. This also keeps them from getting too dirty in the first place, lengthening their lives.

What makes it special?

  • What is great about the Hitop Adjustable Aquarium Heater is its durability. It would be enough for it to keep itself away from the dirtiest parts of the fish tank with its suction cups. But it is also made of special plastic that repels algae and fungi, meaning that it has a long service life that increases its value.

What cons did we find?

  • The big drawback of the Hitop Adjustable Aquarium Heater is its lack of versatility. You get exactly one size of the heater when you get the Hitop Adjustable Aquarium Heater, and that is a 100-watt heater made for fish tanks sized 10 to 30 gallons. If you need a bigger fish tank, look elsewhere.

Best Budget Heater

GMsound Aquarium Heater

Features
  • Type: fully submersible
  • Tank capacity: 10-20 gallons
  • Temperature range: 65-93° F
  • Power: 50W
  • Size: 10.5 x 2.7 x 1.7 inches

More features: easy to read; can be adjusted automatically

Responsiveness is incredibly important to a fish tank heater. You cannot be around the fish tank all the time, so the heater of the fish tank should usually pick up some of the slack. This is where the GMsound Aquarium Heater comes in, as it uses a unique construction to make a highly sensitive heater.

The GMsound Aquarium Heater is a low-power demanding heater that is designed to work with complete autonomy. You still have to set the desired temperature to that of your fish’s habitat, but apart from that, you can leave it totally alone. This makes it a first of its kind from the brand.

What are our favorite features?

  • What is so great about this kind of automatic functionality is that it is, in many ways, more accurate than what a human could provide. You do not have to adjust the temperature or turn it off habitually. It will do that for you, allowing you to rest assured that your fish are comfortable in their new home.

What could be better?

  • The design of the GMsound Aquarium Heater is simple, but if there is a downside, it is its lack of options. It has plenty of options for different levels of heat, but you have to get unique builds of the same product to access some temperatures. This can prove problematic for first-time buyers of a heater.

Best High Heat

SALUTE Aquarium Heater

Features
  • Type: submersible
  • Tank capacity: 10 to 20 gallons
  • Temperature range: 63-95°F
  • Power: 100W
  • Size: 10.8 x 2.8 x 1.7 inches

More features: auto thermostat; adjustable; has two suction cups

Tropical fish can be hard to take care of due to their unique environmental demands. That is what makes the SALUTE Aquarium Heater stand out: its temperature range can go as low as most other heaters, but it can go higher than almost all other heaters, making it ideal for demanding tropical fish.

The SALUTE Aquarium Heater is designed for comparatively smaller fish tanks sized 10 to 20 gallons. There are options that provide enough power for larger tanks, but the fish, the SALUTE Aquarium Heater, is geared towards usually do not need them. This speaks to the heater’s specialization.

Why is it special?

  • That is what makes the SALUTE Aquarium Heater unique. Every fish tank heater we review is trying to please everyone. The SALUTE Aquarium Heater decides that it is going to specialize in tropical fish and their high-temperature demands. In doing so, it does things no other heater can do.

What are the flaws?

  • Naturally, this is also the heater’s biggest drawback. To be the best at taking care of tropical fish, the SALUTE Aquarium Heater gives up its ability to heat larger fish tanks. It can still take care of fish that are not tropical, but there are better options for doing so that provide greater longevity.

Safety is often overlooked when it comes to fish tank heaters. People simply do not expect the devices to pose a risk to anyone or anything’s safety. That is an expectation that the BOEESPAT Small Aquarium Heater is designed around. It is built with safety, readability, and functionality in mind.

The BOEESPAT Small Aquarium Heater is unique from other fish tank heaters by the manufacturer, and in fact, unique from others on the market. This is because it specializes in small fish tanks, providing a low power heat that helps keep them warm without ever overheating them.

More than that, it also shuts off once it reaches its target heat in order to stop its environment from overheating. It also has safety features that turn it off automatically once it leaves the water to prevent it from hurting users.

Why did it make our list?

  • The size and design of the BOEESPAT Small Aquarium Heater are both some of the best we have seen. There is no exposed metal for you or a fish to accidentally touch and no ambiguous thermometers to read. It fits neatly in a smaller fish tank with no fuss when taking it out to clean or adjust.

What is not ideal about it?

  • The biggest drawback of the BOEESPAT Small Aquarium Heater is part of its design, and that is its size. There are no larger or more powerful options for this heater. What you see is what you get. This is a case of specialization paying off big where it is intended and coming with expected drawbacks.

The PERSUPER Aquarium Heater is a fish tank heater that is easy to keep clean and adjust. It uses a unique LED display that makes turning the temperature up or down easily. It can fit into most fish tanks and goes from the high 60s in temperature to the mid-90s, making it great for all fish.

What we found is that the PERSUPER Aquarium Heater is a complete redesign of its previous iterations. No more cylindrical design, no more suction cups, just free-floating plastic with heat emanated from the sides. It also comes in a greater range of power outputs than other models.

Why is it special?

  • The great thing about this redesign is that it is far more intuitive. People will usually get appliances like this and expect to be able to adjust them exactly. They will also be able to touch it freely. Neither of these things is usually true, but the PERSUPER Aquarium Heater goes out of its way to be very intuitive.

What are the flaws?

  • This makes it all the more noticeable that it lacks some of the basic automation that other fish tank heaters have. It does not turn itself off when it leaves the water, nor does it turn off after it reaches its target temperature. That means you have to make a habit of turning it off manually.

Most Versatile

Petbank Aquarium Heater

Features
  • Type: submersible
  • Tank capacity: 5-10 gallons
  • Temperature range: 64-91℉
  • Power: 50W
  • Size: 6.57 x 5.24 x 1.97 inches

More features: LED display; remote control; intelligent temperature control technology; thermometer strip

We have said much about the expectations of a fish tank heater’s design and how it interacts with the actual design of fish tank heaters. The Petbank Aquarium Heater is one such heater made to fill every expectation someone might have on getting their first fish tank heater.

The Petbank Aquarium Heater builds upon its predecessors in two big ways. The first is that it is more safety-oriented and better designed than others. It has a plastic casing that makes it safe to touch when it leaves the waters and temperature control so that it can turn itself automatically.

What stands out?

  • Its greatest feature, though, is its remote control. This wireless remote allows you to control the temperature of the fish tank in a way that no other fish tank heater does. There is no fiddling with nobs and no removing the heater from the fish tank itself. You can do it totally remotely, cutting down on errors.

What cons did we manage to find?

  • The biggest downside of the Petbank Aquarium Heater is its size. It will not be delivering heat to many different sizes of the fish tank due to only outputting 50 watts of electrical heat. Its small stature also means that it has a shorter shelf life, if only slightly shorter than other things like it on the market.

Things to Consider

Now that you have an idea of what the best 10-gallon fish tank heaters bring to the market, you are probably wondering about fish tank heaters in general. Reading a sales pitch about a fish tank heater will only tell you so much in isolation.
The key components of a fish tank heater are the type of fish that it is made for, the tank capacity it is capable of heating, the power that it needs to draw and output, its own size, the manner of its installation, and the range of temperatures it can output.
This probably seems like a lot, so we will go one at a time to give you an idea of what each feature means and which products provide good examples of them.

Important Features

These features all pertain to a question you should ask yourself before buying the heater. For instance, the type of heater you buy will be determined by the type of fish that you have. Some questions are easier to answer than others, though.

Type

The type of fish tank heater you get is entirely determined by the type of fish that you have. Generally, you can separate the type of fish that you have into “tropical” and “subtropical” fish, with tropical fish preferring water warmer than 80 degrees.

Subtropical fish prefer water under 80 degrees but above 60 degrees. Technically there are fish that live in water that is colder than this, but you will basically never own them as pets, especially in a fish tank.

But the type of fish tank heater that you get is not just a matter of the temperature. It impacts every aspect of the fish tank heater you use, from the heat to the safety measures the heater employs. A subtropical fish needs comparatively cooler water than a tropical fish, meaning that it cannot be left with a heater running overnight.

In short, the question of what kind of fish you are getting a fish tank water heater for is one of the biggest questions you have to answer before buying one. Keep this in mind as we go through each of the other features of the fish tank heaters.

Tank capacity

10 Best 10-Gallon Fish Tank Heaters - Perfect for Small Spaces (Summer 2022)

Tank capacity is something you should keep a close eye on when you are buying a fish tank heater. The reason is that a fish tank heater will not be able to raise the heat of a fish tank that is too large.

This is because the device relies on distributing its heat evenly and raising the heat of the whole body of water. If you were to place one of these heaters in the ocean, then it would hardly cause the whole thing to heat up. The same goes for a fish tank that is too big—or rather, a heater that provides too little heat.

Fish tank heaters work by outputting an amount of power that is then turned into heat. That amount of power determines how high this heat can go, as well as how far it can go through the water before dissipating.

The size of the tank that the fish tank heater can heat will usually be indicated on the packaging, as it’s the case with PERSUPER Aquarium Heater. Whether this detail is included or not is determined by the heat it outputs and the amount of power it uses to output that heat. This can make it seem complicated, so you should definitely prioritize a heater that lists these things.

If you want to remember how much heat a fish tank heater provides, think of it like every 50 Watts of power heating up 5 gallons of water to its desired temperature. That means that if it uses 200 Watts of power, it can heat up a 20-gallon tank.

Power

“Power” in this context refers to two things: The first is how much power the fish tank heater draws. This is not too much of a factor you need to worry about, as just about every fish tank heater will require no more power than that of a home outlet.

The only fish tank heaters that require more power than those provided by a normal wall socket are those that are designed for much bigger aquariums. These are not the kind of fish tank heaters you are going to buy unless you are looking for them.

To be specific, a fish tank heater, like SALUTE Aquarium Heater, will take 120 volts to power. For comparison, a food heating pad or clothing dryer will take 240 volts. That means that a fish tank heater’s power demands are no more than a normal household appliance.

Their power output is slightly different. You will want to keep an eye on the power output of your fish tank heater because not only does it determine the size of the space it is capable of heating (as detailed above) but also its risks.

Put simply, and a more powerful fish tank heater will be more dangerous to handle. “Dangerous” is a strong word—you are unlikely to get seriously hurt by a fish tank heater. But “unlikely” should not be misread as “never going to.” It is an electrical device submerged in water, so be careful with it.

Most fish tank heaters come with their own safety features that turn them off when they leave the water. This keeps them from hurting you when you clean them. Just be sure to handle them with care to avoid this in case they do not have this feature.

Size

10 Best 10-Gallon Fish Tank Heaters - Perfect for Small Spaces (Summer 2022)

Even if it does not have a safety feature that will shut it off automatically, fish tank heaters are designed to use the conductivity of the water in their heat production process. That means that if part of their heater is not in the water, no heat is made.

Size is the kind of feature in a fish tank heater that can very easily slip by your notice. The reason why size is important in a fish tank heater is that the heater needs to be completely submerged into the water in order to work. If it is not completely submerged into the water, then there is a good chance it will shut off.

These facts are highly material to the size of the fish tank heater, as a fish tank heater that is too big will easily pop right out of the surface of the water. You want your fish tank heater to either float vertically in the water or lie horizontally on the bottom of the tank. You can also get fish tank heaters that feature suction cups, like FREESEA Aquarium Heater, to attach them to the walls. In all cases, there has to be clearance above and below the fish tank heater to keep it safe.

Installation

Fish tank heater installation is generally easy, although the exact method differs from model to model. Most of the time, you start by submerging the fish tank heater in water completely, then plug it in and turn it on. Only then do you set your desired heat. Rarely will that order of operations change.

It is important that you submerge the fish tank heater before you turn it on, as turning it on first can cause it to shock your hand. It is meant to be submerged in order to function properly, so do that first.

Some fish tank heaters cannot turn on before being submerged anyways, so it is a good habit to make. Just be aware that some fish tank heaters will have you set the temperature before you turn them on.

Some fish tank heaters, like the Hitop Adjustable Aquarium Heater, have suction cups that attach them to the walls of fish tanks that you will need to use before turning them on. These are great for keeping the heater next to a water source.

In short, you should only even plug the fish tank heater in after you have gotten it into its correct position. Only once you are sure you do not need to touch it anymore should you plug it in, much less turn it on.

Temperature range

The temperature range of a fish tank heater is an important factor in which fish tank heater to buy, as some fish prefer wildly different temperatures than others. Keep a close eye on what kind of temperatures your fish want. Most fish tank heaters will be able to handle lower temperatures, as it is incredibly rare that a fish that can live in a fish tank will need its environment cooled rather than warmed.

But if a fish needs 94 degrees Fahrenheit water and your fish tank heater can only provide 91 degrees Fahrenheit, then it simply does not have the ability to sustain your fish. This might seem harsh, but it is the best mindset to adopt for the safety of your fish, as many of a fish’s chemical reactions rely on its body temperature.

This can best be exemplified in the SALUTE Aquarium Heater, which pushes its design to focus on generating the highest heat it can output. Research your fish to see if they have any particular temperature needs. There will certainly be a fish tank heater to accommodate every kind of fish out there.

FAQ

First, place the fish tank heater next to the water flow of your fish tank. That means it will be near the outflow of your filter, warming Trusted Source Warm Water Important for Cold-water Fish Like Salmon and Trout, Study Finds | NOAA Fisheries Cold-water fish need both warm and cold water habitats at different parts of their life cycle. www.fisheries.noaa.gov the water as it goes into the tank. Once it is completely submerged in water, plug it in. At this point, you can set the temperature. Turn it on after you have set it to the temperature you need. You do not need to remove your fish from the tank before you install the fish tank heater, but you can if you want. The fish will not get shocked by the fish tank heater, nor will it output enough heat to hurt them should they investigate it.

A fish tank heater’s use depends on how much of it is automated and what the temperature demands of your fish are. What this means is that most times, you will let your fish tank heater use itself, warming the water to a temperature and then turning it off once the water is warm enough.

But if the fish tank heater is not automated, then you will have to operate it manually. This means that you set it to the temperature you need and then turn it off when it gets there. Many will come with timers to help with that.

You only need to turn the fish tank heater off if your fish prefer a lower temperature. Otherwise, most fish will do fine at the higher temperatures that a fish tank heater can provide.

Heat is a curious thing that is easily taken for granted. Heat is necessary for chemical reactions like digestion and respiration to take place in fish. That means that the warmer a fish is, the more easily these chemical reactions take place. Fish are happier and live longer in warm water, and some fish can only live in warm water due to their physiology. This means that a heater for your fish tank will keep your fish alive longer and will make that life much better for them.
