Buying Guide

I know you might have loads of questions about buying the best titanium aquarium heater for your fish tank and with the huge variety and number of options available, it is obviously very easy to get lost and confused between those options.

So, don’t worry, as this guide has answers to all of those questions and doubts in your mind and help you choose the best titanium aquarium heater to provide a better temperature living environment for your cute little aquatic pets.

Now we are here, reading and searching about titanium heaters for aquariums, but have you thought why only titanium, why not any other metal like steel or aluminium. You will find the answers to these questions along with many certain questions as you read ahead. 

Why titanium?

Titanium is a lustrous transition metal that has a silver colour and low density. Not only this, but it is incredibly durable and long-lasting. Titanium is used in heaters for aquariums and ponds because it is highly corrosion-resistant in seawater, aqua regia, and chlorine. 

Along with its gleaming look and low-density property, this metal is very strong and very light. Even if it is used in medical lines like titanium cages, rods, plates and pins are inserted into the body and can last for more than 15 to 20 years. 

Even dentists use dental titanium, such as titanium posts and implants, which can last even longer. If you can use it for such critical purposes, then why not aquarium heaters. 

Even big fishes and aquatic animals of large tanks like Oscars or turtles cannot knock down your titanium heater proving its reliability and strength.

How does the size of the tank matter?

Mostly when heater problems occur in your tank, it is generally due to the heater being wrong sized for the aquarium. I would suggest you use titanium heaters if you have a big aquarium as they can overheat and burn out when used in small aquariums and tanks. 

This is because they always need to be submerged in water. If the water level drops in a small aquarium and it is easy to heat the full tank volume in very little time, the heater may overheat in confined spaces.

In a large aquarium, heat will dissipate more rapidly, giving no chance to your titanium aquarium filter to overheat or burn out. 

You can still use some in small aquariums with extra equipment like sensors, remotes and stuff to always keep the heater in check and control. If you think your heater will overheat or make water temperature rise more than needed, just shut it off for some time.

Are titanium aquarium heaters expensive?

Titanium heaters can definitely be expensive, but it depends on the company and the standards that manufacture them, their quality, and the additional cost of the heater.

Titanium itself is quite expensive as compared to stainless steel and many other metals, so it is obvious that the titanium heaters price will be comparatively a bit higher and noticeable.

A titanium heater can also be more expensive or less expensive, depending on the watts. Heaters with higher watt values that are mostly used in the huge aquariums are costlier than those with lower wattage used in comparatively small-sized tanks.

Best price for the best titanium aquarium heater

Whenever we go out to buy something, the first thing we look at is its price tag. The human mind has a tendency to tilt towards cheaper options to save some dollars. But sometimes, this can be a compromise with the price over quality. 

Well, this doesn’t mean you need to spend money blindly on kinds of stuff that isn’t of high worth. You will find tons of aquarium heaters starting from 20$ to maybe 100$. Now, which one will you choose?

Going with the cheapest option might not always be a good choice. Before that, you must read the reviews of the people who had already bought the product and used it. This way, you can know if the heater provides expected quality services or not.

This does not necessarily mean that high price heaters are always better and will work perfectly. It still depends on the company that manufactured the titanium heater.

Going with an option with more features and services at the average minimal cost would be a smarter choice rather than buying a high price one without any additional features like thermostat control, temperature showing LEDs and other stuff. 

Features of a titanium aquarium heater

You must look at the services and features that are provided with the titanium heater. They must be designed to be very user friendly. 

Go with the one with led displays that are very easy to read and have good thermostat control, as the control system will monitor any temperature fluctuations that occur throughout the day in your aquarium. 

The heating elements should be constructed from titanium and include top quality components to give precise temperature control, and for the controllers, if the heater is exposed to air at a certain level while it is still plugged in, there will be a built-in sensor that will cut the power. 

Along with this, the most important feature of the titanium heater is its corrosion resisting property. As the most common placement, the heater is submersible inside the aquarium, and it has to be there constantly for a long time.

When talking about titanium heaters, as the outer casing of the heater is completely metallic, there is no glass being introduced inside your aquarium hence reducing another hazard from your dear fish. 

Even compared with other standard submersible heaters, the heat radiation is far superior for titanium heaters. There is less oxidation on the immersed casing causing less rusting even in saltwater aquariums.

Also, in terms of power and wattage, titanium heaters are known for dealing with high wattage, providing sufficient heat and energy to supply in a very large tank and keeping it warm for the fish.


Most of the standard submersible heaters generally go up to 400 watts, but titanium heaters can go up to 800 watts. 

Because of such high power, a very large aquarium that had always been running on two heaters needs just one titanium heater to maintain the surviving temperature of your aquatic creatures.

Water circulation is important 

For efficient temperature control and accuracy in maintaining and raising the temperature of the water of the whole tank equally at all parts, it is really important to have a good water circulation feature or system in your aquarium.

This is because to maintain the equal and proper distribution of heat through the tank, or one side of the tank will remain warmer than the other side.

Some heaters come with pumps for better water circulation, while if your tank does not have a pump, you have to spend a small amount to buy one. 

Check the ratings

Before buying an aquatic heater, it is really important to check its ratings. You can never tell just by looking at the product if it is good or bad, will it work for the aquarium or not, and quality assurance.

This is where the ratings and reviews of the product help you as they are given by the people who have actually bought the product and have been using it or might have used it in the past.

Keep those products first in options that have higher ratings, and the lowest rating products should be kept to be looked at as the last considerable option. You can discard the products of least ratings for your list. 

Keeping ratings in check will not only ensure that you are buying the right titanium heater for your tank, but it provides good features and high performance.

Filtering and categorising products depending on their ratings will not only make it easier for you to choose the right option but also save loads of your time. 

Size of Aquarium Heater

All kinds of aquarium heaters come in various sizes. Some are very bulky, while some are very compact in size. The same goes for titanium heaters.

Smaller heaters are easier to hide in your tank and won’t disturb the look and decor of your aquarium, but they are best for small tanks as they do not provide enough efficiency to regulate the temperature of big tanks.

On the other hand, bigger heaters are more suitable for larger tanks as they have a higher chance of getting burned out in compact tanks than the larger ones. This is due to its high rate of producing heat.


Aquarium heaters are indeed an essential part of your aquarium, and nothing can be more reliable and efficient than titanium aquarium heaters. 

The major role that titanium heaters play in the health and well-being of aquariums remains dominant for providing a perfect temperature for your fish and aquatic pets to live in. 

As finding the best titanium aquarium heater is not as simple as it sounds, I hope that this article helped you in choosing one of the many options available in the market that fits and works best in your aquarium.
