Best Aquarium Heater For 55 Gallon Tank (Review & Buying Guide)

Best Aquarium Heater For 55 Gallon Tank

Aquarium heaters are a necessary and often overlooked part of keeping aquatic life. They provide the required warmth to your tank, ensuring that the fish stay healthy and happy. 

In this blog post, I will particularly talk about Best Aquarium Heater For 55 Gallon Tank.

The 55-gallon tank is one of the most popular sizes for fish tanks as it’s suited to intermediate and advanced levels. And it looks beautiful with a broader view of underwater creatures.

Picking the right heater is crucial for successful aquarium keeping.

However, knowing which one is best for you can be challenging with so many different aquarium heaters available. So, I am here to help!

What Should Be The Heater Size For 55-Gallon Tanks?

A rule of thumb, in general, is that one would need 2.5 to 5 watts to heat 1 gallon of water. So, when it comes to heating a 55-gallon tank, you need roughly 140 – 275 watts.

But you should aim for 200 – 300 watts when buying your heater because the environment temperature is also a factor in getting efficient heating.

If the outside temperature is colder than usual, it’s vital to ensure that you have a heater capable of heating up water at your desired level. The recommended wattage for this would be higher.

Features To Consider Before Buying Heaters For 55-Gallon Tanks

Before you go out and buy a heater, be sure to have your aquarium needs in mind. All heaters aren’t the same; some will work for your tank while others won’t. Also, you need to understand what temperature range is best suited for fish that live there.

Glass Vs. Titanium

When you look for an aquarium heater, glass is the most common material. However, if you want the best quality heater, consider titanium tubes because they’re more durable and reliable than other options like borosilicate or quartz.

Adjustable Vs. Fixed Temperature

An adjustable heater will allow you to set the temperature according to your needs. A 55-gallon tank is a large tank and usually houses different species. So it should have an adjustable maximum and minimum range that ensures all tanks occupants are comfortable.

A heater with a fixed setting may not give you enough flexibility and control over your tank’s environment, so it could be better to purchase one that has an adjustable temperature control instead.

Submersible Vs. External

For 55 gallon tanks, ideal heaters are submersible ones. These types of heaters usually come slim in design and take up minimal amounts of space, so you can house your fish and plants more efficiently.

The submersible can offer better temperature control in larger aquariums, so that’s what I recommend for those who want a smooth experience with their aquatic pets.

Still, external or hang-on options might be a good choice as well!

Safety Feature

When choosing a heater for your tank, there are several safety features you need to consider. One is an auto shut-off feature that turns the device off when it reaches its preset temperature.

Also, you should ensure that the heater you choose has a safety feature like it will turn off automatically when taken out of water.

Be on the lookout for heaters made out of shatterproof and shockproof materials because these are less likely to break if they fall off-balance.

Ease Of Maintenance

Many heaters are very hard to open and access the internal components for cleaning – avoid these complex models! Instead, choose simpler ones with easier-to-open designs and smooth reassembly inside the tank.

Digital Vs. Thermostat Control

An aquarium is a showpiece, and aesthetics are vital. A digital aquarium heater is more for visual appeal than convenience. The LED temperature control changes color whenever the desired range has been crossed, but that’s all there really is to it!

Display

It’s helpful to have an easy-to-use control panel if you buy an aquarium heater. Look for heaters that show the current temperature in big numbers and display your preset temp on the screen. 

Just keep one thing in mind; these models are usually more expensive than others!

Warranty

To get a good deal, you should always watch out for warranties because they can be very helpful when things go wrong with your product.
