Hygger Titanium Aquarium Heater, The Perfect Choice For 2021!

Hygger Titanium Aquarium Heater Review by Aquarium Tales

Most freshwater and saltwater fish are comfortable at the water temperature variation from 72 to 80 degrees Fahrenheit. So, it is essential to maintain your aquarium water temperature within a specific range. You cannot do it without an aquarium heater.

Most vendors do not include a heater with the aquarium kit box, so the heater is an additional but must-needed accessory. You have to buy a heater for the aquarium, and you have to choose the right one. Hygger Titanium Aquarium Heaters can be the perfect match as they are vastly compatible with any aquarium.

Here you get four different sized submersible heaters of 50w/100w/200w/500w from the Hygger. Pick one that suits your aquarium size and other requirements.

Hygger Titanium Aquarium Heater​ Review

The Hygger Titanium Aquarium Heater is a submersible aquarium heater, which means it must be fully immersed in the aquarium water. Submersible heaters are relatively more efficient than external-type heaters. This Hygger heater is available in four different sizes that will cover a wide range of fish tank sizes from 5-gallon to 120-gallon.

How to Choose the Right Size

Hygger Titanium Aquarium Heater Sizing Guide

The right size indicates the aquarium heater’s proper capacity to raise the water temperature to the setpoint. The desired capacity depends mainly on three factors, room temperature, tank size, and the ideal temperature setpoint for your fish.

As a rule of thumb, you can do simple math to identify what capacity you need. Multiply the gallon number of the tank with the desired temperature rise (in degrees Fahrenheit). Take the result as your heater’s watt.

For instance, in a 5-gallon tank, if your set temperature requirement is 10 degrees above the room temperature, the watt requirement is 50. Similarly, for a 10-gallon tank and 15 degrees of temperature rise, you will need a 150-watt heater. But remember, you have to consider the maximum temperature that you need to uplift.

An undersized heater remains turned on all the time as it struggles to reach the set temperature. This scenario can overstress the heater and eventually ends up with a short duration of the heater’s life.

Features of Hygger Titanium Aquarium Heater

In submersible heaters, I feel more comfortable using a titanium heater like this one as it’s safer than glass heaters. I had a bad experience getting an electric shock from a glass-made submersible heater.  Accidentally, I electrocuted the entire aquarium water as I broke the glass shell and exposed the heating coil.

In this Hygger heater review, I’ll discuss features that usually every fishkeeper would love to have from an aquarium heater. Let’s have a look at the features of the Hygger Titanium Aquarium Heater.

Precise Temperature Control

A separate temperature controller will allow you to adjust the temperature effortlessly for this Hygger Titanium Aquarium Heater. As you don’t have to take the heater out of the tank for setpoint adjustment, it benefits accurate control.

The heater automatically shuts off, reaching the set temperature. The heating temperature range is broad enough, from 32 to 104°F, with a control accuracy of +/- 0.5 °C.  A good one!

A Versatile Heater to Use

This heater is suitable for freshwater, saltwater aquariums, and reef tanks. As the construction material is Titanium, so it is entirely corrosion-proof and durable. They hadn’t use glass in the construction. Therefore, the Hygger Aquarium Heater is shatter-proof and not prone to fragility.

Temperature Monitoring

You can see the temperature settings from an LCD monitor on either Celsius or Fahrenheit scale. An external thermostat measures the water temperature, which is visible on display.

The display shows the water temperature up and the set temperature down, thus quickly identifying whether it maintains temperature correctly.   

Available in Different Watts

Four different sizes of Hygger Titanium Aquarium Heater are available. They are 50, 100, 200, and 500 watts. You can pick the right size based on your requirements. 

Horizontal Placement

This horizontally placed submersible heater can be mounted on the tank with two suction cups. This feature provides the benefit that you can set the heater anywhere at any water height you want. Maintaining the water temperature can be more manageable, placing it near a steady current flow (with a pump).

Alternatives: If you don’t prefer a submersible one, which places inside the aquarium, you may go for an external type heater that can be installed externally along with a canister filter and sump.

Suitable Heater for Most Species of Tropical Fish

The manufacturer designed this heater, making it a suitable match for Betta fish tanks, to maintain a uniform water temperature inside the whole aquarium. But keep in mind that this heater is only useable in glass tanks. 

Not only for Betta fish but also for most other popular aquarium fish, the Hygger Titanium Aquarium Heater is equally efficient.

Pros and Cons

  • Equally efficient for small and large tanks.
  • The extended Power cable is convenient to use.
  • It is easy to reposition with suction cups. 
  • The Titanium is not fragile like glass, so it is durable. 
  • Useable in freshwater and saltwater. 


  • It is not suitable for an acrylic tank.
  • The thermostat is not waterproof.
  • There is no guard of the heating element.

Safety Precautions

The aquarium heater is the most sensitive equipment of your fish tank, and it requires cautiousness to operate safely. Here I am discussing some safety precautions for using the Hygger Titanium Aquarium Heater.

1. Keep it fully immersed

Never start the heater unless the heater rod and the temperature probe are fully submerged in water. It is a necessary precaution for submersible aquarium heaters. If it runs dry, overheating is the consequence, that can eventually burn the heater. 

2. Do not burry it under gravel

Do not bury the heater undergravel. It will cause overheating as gravel doesn’t transfer heat as quickly as water does.

3. Set fully before power-up

Never power up the heating rod alone. Always connect the temperature probe and the thermostat while using. Without getting the actual water temperature and the desired setpoint as inputs, the heating rod may keep running to overheat.

4. Always keep water circulation

Keep water in circulation when the heater is on. The water circulation will distribute the heat uniformly. If water is not continuously recirculating, it can cause localized overheating of the water.

5. Keep a distance between the heating rod and the probe

Do not put the thermometer (temperature probe) too near to the heating rod. The probe senses the water temperature, and the controller turns on/off the heating rod accordingly to meet the set temperature. It cannot sense the entire aquarium’s true representative water temperature if you place the probe too near to the rod.

6. Cool down before maintenance

Before taking the heater out for any maintenance, shut it off and allow at least 30 minutes to cool it down. This step is crucial for your own safety. Otherwise, you may suffer from a heat burn touching it. It’s too hot!

7. Only use the dedicated controller

Do not use the temperature controller for other brand heaters; vendors prohibit it for safety reasons. A wrong controller can malfunction, which might be dangerous for your fish.

How to Set Temperature for Hygger Titanium Aquarium Heater?

  • Place the heater and probe inside the aquarium and ensure both are fully submersed.
  • Plug-in for electric power.
  • When you power it up, a red light indicator is on, and the heater starts functioning.
  • You can see the water temperature from the LCD.
  • Adjust the set temperature by pressing adjustment buttons on the controller.
  • The display will show the set temperature that blinks for three seconds, and now it’s all set.
  • To shift the temperature unit between Fahrenheit and Celsius, use the ‘Up’ button.

Frequently Asked Questions (FAQ)

Does the heater controller retain its set programming after a power outage?

Yes, the setpoint retains the last value. You do not need to re-adjust. The only problem is the temperature unit reset to Celsius by default. If you want to see it in Fahrenheit, you will have to change it manually again.

Where to put the temperature display?

Unfortunately, there is no hook or suction cup to fix the display controller somewhere secured. You will have to find a place like a dresser or a side table to put it.

Can I place Hygger Titanium Aquarium Heater vertically in my aquarium?

The vendor does not recommend it. The heater is too long to place vertically. If your tank is not large enough, you can’t keep it submerged by vertical placement.  It would be best if you kept it fully submerged to prevent overheating and heater burnout. Besides, heat distribution is better in the horizontal installation.

Final Words

A nice little heater, I will happily recommend it for your aquarium to keep your small pet’s home warm and cozy. For the best performance of the heater, the vendor Hygger recommends using a pump that circulates water. If you place the heating rod somewhere near the pump discharge, warm water distribution will be better.
