Best Heaters and Chillers of 2022

Fish and other aquatic pets need a stable water temperature in order to survive and an aquarium can be very susceptible to temperature fluctuations. For this very reason, reliable temperature control and monitoring are among the most important parts of your aquarium build.

We put together a list of our most trusted aquarium heaters along with our best-selling aquarium chiller. Each of the different heaters on the list provides a unique value to tank owners and receives the highest ratings across the category.  While chillers are nowhere near as common as they once were, we highlighted just one brand that happens to be one of the best-selling and most versatile lines of aquarium chillers in the industry.

 

AquaEL Ultra Heater

AquaEL Ultra Heater Coral Mounts

AquaEL Ultra Heater is not really a throwback rather a new version of a heater design that hit the market just a few years back and brought some really cool advantages to the heater game. It's plastic and it's flat, two things we just don't see on other heaters.   

Plastic means it's very durable and will hold up to accidental bumps or drops. The profile is flat which is super convenient for AIO tank owners because it fits pretty much anywhere. In between baffles but also flat up against the back wall of your tank. The digital dial is also unique with a single button that changes between the set temps.  You also get an indicator that displays the water temperature or overheat when in operation.

 

Eheim Jager

Eheim Jager

The classic Eheim Jager has long been a favorite because of the accuracy you get with the controls. While it is glass, it is made of Pyrex which is a super durable glass material that will withstand moderate abuse. 

What makes the Jager special is the calibration feature. It has two dials, one that controls the set temperature and another that allows you to essentially calibrate the water temperature reading and compensate for any variances. All thermometers are going to have some level of variance and with this calibration feature, you can synchronize the heater's temp. reading using a separate calibration thermometer. 

 

Innovative Marine Helio PTC Smart Heaters

Innovative Marine Helio PTC Smart Heaters

Innovative Marine Helio PTC Smart Heaters are among the newest of the bunch and are notable for the redundant protections.  

It uses a digital temperature controller that is separate from the titanium elements which means you can replace either component with ease. The controller gives you the ability to not only set your temperature down to 0.1° F but you can also set a low and high-temperature alarm to notify you if something goes wrong. It can control two heating elements and features a remote titanium temperature sensor with a magnetic mount for easy monitoring in your display aquarium. 

The durable titanium elements provide their own level of redundancy and are the first heater elements to be controlled by an internal microchip. The chip won't allow the heaters to rise beyond a set internal temperature which reduces the chances of a dangerous overheat. The ability to run two heating elements side by side adds another layer of protection against underheating the water; should one element go out, you still have another functioning element to prevent dangerous temperature drops.
