If you are looking for one of the top-end aquarium heaters that are feature-rich, you can’t go wrong with the Fluval E Series heaters. But do they deserve the top spots in the best aquarium heaters list? Are there any flaws? Read on till the end to find out!
What I Like About The Fluval E Series Heater:
The Fluval E Series Heater has a handy LCD display which I like the most. The heater’s LCD screen displays the water temperature in real-time and communicates the reading in Celsius or Fahrenheit.
The most helpful feature is that it comes with a color-coded alert system.
Here’s an example of the color the LCD screen in the Fluval E Series heater would display based on the temperature:
The LCD screen will change color to let you know about the safe zone temperature and the high/low fluctuations.
The temperature reading will change color if the water temperature varies +/ – 2° F or more from the pre-set temperature.
So whether you are just passing by your aquarium or before sleeping, you can just take a quick look at the color of the heater’s LCD screen and have that peace of mind. You don’t need to worry if it’s green, as it indicates the safe zone.
But if the color is red or green, you can investigate and solve the issue quickly to prevent any potential damage related to low or high temperatures. That’s helpful.
Another cool thing I like about the Fluval E Series Heater is they come with a protective casing – heater guards.
A heater guard is a cover (usually made of plastic) that encloses your aquarium heater. It helps in protecting the heater glass from any physical damage. Also, it prevents the fish from coming in direct contact with other tank decors and the fish.
Even though the heater burning issue with fish or tank decorations is not so common, we still can’t rule out the possibility. So it’s better to be safe than sorry and have an aquarium heater guard.
With Fluval E Series Heaters, you don’t have to spend anything extra for the heater guards, as it already comes along. Hence, that’s an added benefit you get!
What I Don’t Like About The Fluval E Series Heater:
The first thing I dislike about the Fluval E Series Heaters is their cost. For instance, the Fluval E300 (A 300 Watt Fluval E Series Heater) is more expensive than other best aquarium heaters on the market, like the Eheim Jager Aquarium Thermostat Heater 300 Watt.
But you also get the added benefit of the Fluval E Series heater, which is missing in Eheim Jager.
In Eheim Jager, you only get an on/off indicator light and no heater guard. On the other hand, Fluval E series heaters have an advanced LCD with a color alert system and a heater guard.
So the Fluval E Series Heater is worth the price if you are willing to spend for the added benefits you get in return.

Another problem that could be an issue with Fluval E Series heaters is the flow rate issue. If you don’t set up the heater properly, you will probably keep receiving an “LF” warning – a Low Flow rate issue in the LCD display screen, which you might not like.
One of the important criteria for setting up the Fluval E Series heater is to locate it correctly in your tank, in an area with good enough water flow. The water flow should be directed towards the top side of the case enclosing the heater, as the sensors are located in that area.
The aquarium heaters generate heat using electrical energy. And as the heater starts functioning, the surrounding water gets warmed up and comes to the required temperature we want.
Hence, it is important to have proper water circulation in the tank to get a constant temperature throughout your tank. Otherwise, areas of hot and cold pockets will arise in the tank water, which is not great for the fish.
Aquarium heaters are pretty compact in size compared to the amount of heat they produce. So it is essential to have adequate heat exchange in their surroundings or else they would get damaged.
Now, most normal aquarium heaters are not equipped with such advanced sensors that can tell us about the low flow warning. But with Fluval E Series heaters, you can get this opportunity.
So even though receiving an LF warning can be an issue, it’s actually the specialty of this heater. And by setting the heater near a high water flow area (near the outflow area of a powerhead or filter), you shouldn’t face any problems.
