If you have a 50-60 gallon tank and need a heater for your aquarium, a 200-watt heater is what you need. A 200-watt aquarium heater is suitable for keeping the water temperature stable and safe in this type of fish tank.

This is an important purchase for your fish tank because failing to regulate the temperature may negatively influence the aquarium’s inhabitants. So, to help you choose the best and most efficient 200-watt heaters, we examined a variety of goods in this area.

We discovered various incredible products, but the Eheim Jager Aquarium Thermostat Heater is the greatest and most notable. But don’t worry if you’re looking for a different design or brand; we’ve included nine more fantastic products in this list.

So, what are we waiting for? Let’s get started on the list right away.

10 Best 200-watt Heaters – Reviewed

All the products mentioned below are available online on amazon.com.

Eheim Jager Aquarium Thermostat Heater

Product details:

  1. 200 Watt
  2. Made in Germany
  3. 65° to 93° F

When it comes to even temperature control and simplicity of access and reading thermostat controls, Eheim boasts excellent and precise features.

This heater is preset to 80 degrees Fahrenheit. After some tinkering, I discovered that it keeps my 10-gallon tank at 80 degrees with the thermostat set to 75. In warmer climates, you might need to modify the thermostat once the temperature drops significantly.

One thing to keep in mind is that this 50-watt heater is around nine inches long. That’s a lot more than any aquarium heater in the 50-watt range I’ve tried.

I enjoy how the numbers on the thermostat dial are easy to see. Also, because the heater is so tall, the thermostat dial is extremely close to the surface of my tank. All of this makes it very simple to set the thermostat without having to fiddle with it endlessly.

Having to remove the heater from the tank is very time-consuming work, and this heater prevents that part for you quite efficiently. When the heater is turned on, an amber indication light illuminates. The two suction cups that hold the heater to the wall work quite well.

So far, after about six months, the heater is performing admirably, and I am delighted with this device.

What we like:

  1. High quality
  2. External controls

What we dislike:

  1. Not durable

hygger 200W Digital Quartz Aquarium Heater

Product details:

  1. 110-120V/60HZ
  2. Digital LED Display Controller
  3. Quartz Tube

The hygger 200W Digital Quartz Tank Heater has significantly superior quality than any other aquarium heater. It efficiently maintains the temperature of your aquarium. This heating system is easy to use in every way.

It’s amazing to be able to change the temperature and readily read the thermometer with its digital screen. I used it in my 40-gallon breeding tank. It did an excellent job of keeping the temperature stable. It’s little and dark, so it blends in with the background.

The instructions are straightforward, and the installation is simple. The digital controller has a clear and bright display. In comparison to other heaters in this price range, the heater itself appears to be highly efficient.

It can heat a 40-gallon tank in a matter of minutes and has no fluctuation concerns with its heating mechanism. Maintains temperature exactly at 25 degrees Celcius with little deviation. The only drawback is the suction cups tend to lose strength with time.

What we like:

  1. Extremely efficient
  2. Accurate temperature control

What we dislike:

  1. Suction cups are not very sturdy

AquaTop Titanium Heater

Product details:

  1. 68F – 92F
  2. Titanium construct
  3. Remote sensor

This is one of the best heaters for the hobby. A computerized reader makes it simple to set the temperature. Overall, the temperature is quite steady. Because the glass is composed of titanium, I don’t have to worry about it ever breaking.

This is a bit more expensive than most other water heaters, but its dependability and durability make it worth every penny. Simple to operate, with high accuracy, though you may need to fine-tune the parameters for your tank.

It’s so nice to have the heater control outside of the tank, and it’s simple to adjust the temperature up or down. My temperature sensor is located near where the water exits the filter and works flawlessly.

It comes with a highly accurate controller. I double-checked the indicated temperature with a verified thermometer, and it is correct. I adore it, and my fish are happy; I haven’t had any problems with it yet.

What we like:

  1. Accurate temperature control
  2. Easy control

What we dislike:

  1. A bit on the expensive side

hygger Titanium Tube Aquarium Heater

Product details:

  1. 200 watt
  2. 20–45 gallons
  3. 32-104°F, ±0.5°C

Great and compact heater. One of the most effective products I’ve ever used. I like how simple it is. As well as the precision of temperature regulation. It is smaller and easier to conceal than other heaters of its size.

It’s also quite strong, so you can conceal it under rocks or put it in a tank with aggressive fish like Oscar and discus without worry. Great power for my 90-gallon tank, and having the temperature and settings visible outside the tank is a plus.

There is no longer any algae fiddling with my heater, making it impossible to monitor the temperature setting or see the display light. You can put the temperature sensor on the opposite end of the tank to ensure that the entire tank is at the proper temperature.

With large red numerals, you can always see the current temperature and the set point. The set temperature remains on point, which is wonderful, but the exchange between Fahrenheit (F) and Celsius (C) causes the temperature to drop a degree F lower than what it is set to.

What we like:

  1. extrenal control
  2. Compact design

What we dislike:

  1. Not very durable

Fluval M50 Submersible Heater

Product details:

  1. 200 watt
  2. 65 Gallons
  3. 66-86°F

This small heater is ideal. This heater works well and looks good in my 55-gallon freshwater tank with live plants, mollies, tetras, snails, and shrimp. The temperature control is easily situated at the top of the heater and is extremely precise.

I have a thermometer on the opposite side of the tank from the heater, and it registers temperature changes about a minute after I adjust the heater. This isn’t a big deal for me because I have the heater nestled in a corner and it remains put despite the suction cups.

The heater is thin, and the shiny surface is fascinating. I believe it does a good job of not standing out like other heaters. The suction cups are huge, of good quality, and appear to stick well. The power chord is also quite long, which I love.

The suction cups are initially quite efficient, but with time they might lose their strength. This is a common issue for most aquarium heaters.

What we like:

  1. Precise temperature control
  2. Compact design

What we dislike:

  1. Weak suction

Cobalt Aquatics Flat Neo-Therm Heater

Product details:

  1. 66-96°F
  2. Resin/Thermoplastic Heater
  3. Fully Submersible

It is extremely simple to use: simply press a button to pick the desired temperature, and two LEDs display the setting and current temperature. Completely waterproof, with a set-and-forget accuracy. The fresh, sleek appearance struck me; it was very modern and high-tech.

It wasn’t a tube shape, but it was flat, which seemed to provide more surface area in touch with the water. The LED readout is an excellent method to check the temperature of the water at a glance, and it tells you whether you’re over or below the temperature you set for the machine.

One solid LED indicates that your set temperature and tank temperature are the same. A flashing light before or after your preset temperature indicates that it is higher or lower. To change the temperature, press a button at the top of the heater.

This heater is solid-state, and the maker claims that if the unit malfunctions, it will simply turn off and not continue to heat the water. This feature alone justifies the purchase for me. The Neo- Therm’s precision is dead-on, as I tested the unit’s +/- 0.5 Fahrenheit degree accuracy using a digital thermometer.

What we like:

  1. High quality built
  2. Easy to view display

What we dislike:

  1. Needs proper miantenance

Orlushy Submersible Aquarium Heater

Product details:

  1. 30 to 40 gallons
  2. 110-120V
  3. 68 to 89°F

This heater is small, yet it is remarkable. It’s substantial and considerably sturdier than the others I’ve had. In my 55 gallon tank, the temperature indicator is fairly accurate. The design is sleek and contemporary.

The dial is a little difficult to operate with one hand, which is probably a good thing if you have large fish that might bump it. I like that it is completely submersible. Some water heaters cannot be totally immersed, which is inconvenient when the tank is covered.

Another advantage is getting a digital thermometer as a bonus with the water heater for the same price. In this case, I like the digital display. Using two suction cups, you can stick it anywhere you want.

Because the sensor is completely in the water, I believe I am getting a more accurate readout of the temperature in my tank. The only drawback is that the suction cups, two for the water heater and two for the digital thermometer, take an eternity to adhere to the surface.

What we like:

  1. Digital display
  2. Affordable price

What we dislike:

  1. Suction cups are inefficient

ViaAqua 200-Watt Quartz Glass Submersible

Product details:

  1. High quality quartz glass
  2. Fully-submerisble
  3. Visible temperature setting

Let me begin by saying that this heater is fantastic. It’s just over the gravel line, and the water line indicator and my tank’s water line are a perfect fit. I’ve had it for four months, and it appears to be doing an excellent job of keeping my community Betta tank warm this winter.

I set the gauge on this heater at 82 degrees Fahrenheit, and the water temperature was 77 degrees Fahrenheit, not too shabby. Just a piece of information I’ve had it for four months, and it’s still doing great. 

Once you figure out the gauge, as I’m guessing they’re all a little different, you’ll know where to set it. I’ll say this if I turn it down two degrees, it lowers the water temperature two degrees, and vice versa.

It stays in place, but the suction cups should be on longer stems because the top of the heater presses against the tank’s edge, and the top suction cup barely touches the glass. A 1/4″ longer stem from the heater clamp to the cups would be ideal.

But, as I already stated, it remains in place; therefore, it barely accomplished the mission there.

What we like:

  1. Perfect for medium sized tanks
  2. Strong suction cups

What we dislike:

  1. Difficult to setup

NICREW Preset Aquarium Heater

Product details:

  1. 40 to 75 gallon
  2. Preset to 78°F
  3. LED indicator

I’ve had it in my tank for about two months, and it’s been fantastic. The temperature in the room is roughly 69 degrees Fahrenheit. My tank is now constantly about 78 degrees Fahrenheit, and the corals are content.

When the device is heating, the small red light illuminates, letting you know that it is still operational. I did not use suction cups in my tank because there is a section for the pump and heater in the aquarium that I am using.

I enjoy how the heater’s light is bright enough for me to see if it’s operating without having to remove the heater. I appreciate how it has an automatic feature (on/off) and a preset temperature of 78F. (I checked with a thermometer).

The ideal water temperature keeps my Molly fish happy and healthy. Very simple to use and clean. If you place your aquarium far from an outlet, be sure the cord is long enough.

What we like:

  1. Extremely cheap
  2. Precise temperature control

What we dislike:

  1. Suctions are a bit weak

Aqueon Adjustable Pro Aquarium Heater

Product details:

  1. 68 to 88°F
  2. Auto Shut-Off
  3. 75 gallons

Since the fall, I’ve been using this heater in my outdoor 60-gallon pond. It sits in your tank with two suction cup hooks and is simple to use. You can adjust the temperature from 78+/-6 degrees Fahrenheit in 2-degree increments.

This heater can be submerged in my aquarium in either a horizontal or vertical position. It has a red light on it that illuminates when it is heating. The only complaint I have is with the temperature control knob.

The heater’s knob came undone or simply fell off one day. When it comes to in-tank heaters, this is one device where you get what you paid for. So it’s certainly worth the extra money to get one.

It would have been more convenient if there was a green indicator upon reaching the target temperature. Also, the lights could be brighter to ensure that it is operating, but the lack of light is acceptable so that it blends in with the tank.

What we like:

  1. Easy to setup
  2. Worth the price

What we dislike:

  1. Knob is too tight

How to select the Best Aquarium Heater of 200-watt for Your Tank- Buying guide

Even though cold weather does not cause a dearth of dissolved oxygen in the water as it does in hot weather, it is not comfortable for your fish or plants. During such low temperatures, they are subjected to extreme stress, and mortality is visible.

As a result, it is best to take action to prepare for such a climate. And the most effective remedy will be an aquarium heater. But it is necessary to consider some key points before choosing your heater. 

Type of heater

Submersible

A heater must be entirely submerged in water to function; they can often be set vertically or horizontally within the tank. Submersible heaters are popular because you may use them in freshwater and saltwater tanks and efficiently heat tanks of various sizes.

External

External heaters are situated outside the aquarium and often use a small hose as their heat source, hanging over the tank’s edge at the top. They are a fantastic alternative for small and medium-sized tanks because they do not take up much space in the little area you have. However, because of this, they may not always disperse heat evenly.

External-Inline

Inline heaters are similar to exterior heaters in that they must be connected to the tank filter system and heat the water as it is pumped back in. As a result, they can be fiddly and difficult to set up. They may also require additional parts to function properly.

Substrate

Substrate heaters are sometimes concealed as rock, sea bedding, or other sealife plants. They can be heated via a wire hidden beneath the tank’s sandy base if you’re looking for something a little more aesthetically beautiful. However, these are not particularly practical methods of heating an aquarium and are quite uncommon.

Among these different types of heaters, the most preferred type is the submersible heaters. They have a quicker rate, can dissipate heat efficiently, and are most easy to set up.

Cobalt Aquatics Flat Neo-Therm Heater is an amazing heater with a fully submersible feature.

Wattage requirement

Rather than being identified by size, heaters are generally classified by the number of watts they produce. The more wattage you require, the larger your tank.

When it comes to a 200-watt heater, it is most suitable for controlling the temperature for a 50-60 gallon tank. If this is not followed, your tank might become prone to overheating, which is not desirable.

Eheim Jager Aquarium Thermostat Heater is the best aquarium heater among the top 200-watt heaters.

Thermostat feature

When it comes to aquarium heaters, a thermostat is essential because it simplifies altering the temperature. These frequently include legible LED screens that constantly update you on the current temperature of the tank, allowing you to stay on top of what’s going on.

Eheim Jager Aquarium Thermostat Heater is the best aquarium heater with an inbuilt thermostat that accurately measures the temperature and displays it.

Safety and automatic shutoff

To begin, ensure that the heater you’re purchasing is entirely submersible; most are, but it’s always a good idea to double-check. The automatic shutdown functions are excellent. These will turn off the heater automatically if the water level in your tank falls below a certain level or the heat in your aquarium rises above a certain threshold.

Another important feature is a digital display that will enable you to determine whether the heater is running or has stopped working. Some heaters also come with a digital display that shows the temperature at which it is set.

Although this feature can be faulty, monitoring your aquarium and rechecking the temperature with an additional thermometer can save you from damaged or broken units. It will save your fish from freezing if the heater stops working or overheating if the temperature exceeds the set point.

For this, we recommend you hygger 200W Digital Quartz Aquarium Heater. It has an accurate LED display with precise temperature control.

FAQ

How many watts should my aquarium heater be?

The basic rule for heater wattage is to utilize between 2.5 and 5 watts per gallon of total water volume in the aquarium. But, depending on how much you want to elevate the temperature, additional wattage is usually needed.

How many gallons can a 300-watt heater heat?

200-watt heaters are suitable for aquariums larger than 40 gallons, ranging from 40-60 gallons.

Do you leave a fish tank heater on all the time?

Yes, you can leave the heater on all the time. Aquarium heaters contain an integrated thermostat that switches off the heat when it reaches a certain temperature, allowing the water temperature to remain within a few degrees of the intended setting.

Can fish burn themselves on the heater?

Although unlikely, this is a possibility. It only occurs when a fish gets trapped between the aquarium glass and the heater. Secondary infections are the most dangerous concern for heater burn wounds. Although it is relatively rare, you should take precautions to keep your fish from being burned by your aquarium heater.
