What Others Say

When looking at what people had to say about the Aqueon Pro Aquarium Heater, we were impressed to see the majority of consumers had great things to say about it. Customers who have had the heater for several years reported that it continues to work just as well as it did when they first purchased it.

There were a few people who mentioned that after 3 or 4 years, their heater stopped working. They went on to report that the Aqueon company does honor their lifetime warranty, and these folks received a new unit.

There were people who were impressed by how powerful the heater was. They went on to say that it was able to heat their aquarium really quickly, but they also commented the temperature was very accurate as well.

Customers liked that this heater is fully submersible and the suction cups well. Some mentioned the temperature detection and auto-off switch were useful features. People also mentioned they found the heat distribution of the heater very even and it wasn’t at all centralized.

Although the majority of consumers who purchased this aquarium heater had positive things to say about it, there were some people who were disappointed with the product. Of these critical reviews, a few people said the heater killed their fish.

One customer mentioned the heater cracked down the middle and the toxic internal components of the heater contaminated the water, thus killing their fish. This particular individual went on to say they contacted the company and while they would replace the heater, the customer said the company wouldn’t do anything about the fish.

Another person said their heater cracked and they believe their turtle died as a result of the toxins inside the heater.

Although other customers didn’t have such tragic experiences, they still were not pleased. These customers mentioned that the dial on their heater was not accurate and it had a tendency to cause the temperature to fluctuate. Some have said the temperature is off by as much as 5 degrees.

One customer said they were able to adjust the temperature and it would stay accurate for a while, but they were afraid it would drop lower and potentially harm their sensitive fish. A small handful of people said the heater they received was either damaged upon arrival or it didn’t work as it was supposed to.

One hooked their heater up to a HVAC technician’s amprobe and they discovered a 150 watt heater only runs at about 137 watts, to which they were quite upset because they wanted a 150 watt heater.

Final Thoughts

The Aqueon Pro Aquarium Heater is designed to be versatile, long lasting, and effective. This submersible heater is available in several different wattages, so you will be able to heat up your aquarium. If you have a tank larger than 75 gallons, you will need two, but for those who have modest aquariums, this is a great option.

We like this particular aquarium heater because it has an easy to use and easy to read dial to which you can control the temperature. The heater is within 1 degree of accuracy, which is pretty decent. We also appreciate that there is an indicator light that lets you know when the heater is on and when it is at the designated temperature.

The construction of this heater is impressive – from the durable materials used, the strong suction cups, and the accurate, easy to use dial. If you’re looking for a heater that will stand up to large fish bumping into it, this is your heater.
