Quick Overview

Heaters are by far one of the most important pieces of equipment on any reef tank. Finnex has been making high quality, compact electric, titanium heaters for years and allow you to create a safe and very stable temperature within the tank. The titanium body of the HMX-S heater is virtually unbreakable unlike glass heaters and are corrosion resistant.


The new and improved controller on the HMX-S series has been modernized, with a touchpad control interface, and a crisp LCD display, allowing you to know the temperature of your tank at a glance from across the room.


All HMX-S heaters now include a plastic guard to cover the heating element portion of the heater. That will help keep any equipment or livestock from coming into contact with the element and overall making a much safer environment within the tank.

Product Questions

Can these heaters be recalibrated?
Question by: Fawn on Jul 16, 2016 4:21:00 PM
Hi Fawn,
The HMX-s heaters cannot be calibrated, however if you ever do notice their temperature is off, just use it as a reference. In all honesty depending on what your reference for temperature is, the heaters are usually pretty accurate within a degree or two.
Answer by: Charlie (Admin) on Jul 18, 2016 9:56:00 AM
Hello. Does the display just show the setting, or does it also show the actual temp of the water? In either case, how accurate is the display? (My current heater is set to 75 but the actual temp on two different digital thermometers is 77.)

Lastly, is the display pad waterproof?

Thank you.
Question by: OnalaskaBill on Apr 28, 2016 12:26:00 PM
Great question!
The Display will be used to set the ideal temp, after a few seconds it will display the actual tank temperature. The display will be +- 2 degrees. Teh display is not water proof and will need to be placed with care. This is slightly water resistant but not proof.

Is the LED display on these heaters water resistant? I had an older version of this heater, and it died after only a few weeks. Was told it was water damage to the controller, which was sitting on the side of my sump.
Question by: Ryan Braunberger on May 4, 2016 10:46:00 AM
Great question!
This will have a plastic cover and may be able to prevent small splashes however this is not designed to be water resistant and if water is left on it or creeps through the connection will cause damage.

HMX Owners Manual

 

Finnex HMX-S heaters come with an attached digital, touchpad controller that will allow you to precisely set the temperature within your aquarium. These heaters are great for fresh or saltwater aquariums that require a stable, and safe heating system. The HMX-S heaters will keep the temperature within a range of +/- 2 degrees from the set point and with the heating indicating LED you will know when the heater is producing heat or not. Additionally, Finnex digital heaters are equipped with memory. so in the event there is a power outage, your heater will resume your preset temperature settings at start up. Please note that the digital display reads in Fahrenheit.

  • Innacurate By Peter on 11/29/2016

    Nice looking unit but thermostat reads about 4 degrees too high when the heater is on. I guess the heating element is impacting an internal temperature sensor. Placing the heater in area with substantial water flow -- next to return pump in sump -- did not help. I have replaced this unit with a Finnex heater that does not include a thermostat, and a separate Finnex thermostat-controller that has a temperature probe at end of a wire so it can be placed far from the heater. That setup is working great.
  • Unreliable so far By Jeff on 11/24/2016

    This heater looks nice and looks like it was money well spent but I placed the heater tube horizontally in the bottom of sump and placed the led display on the front face of sump and turned it to 80*. This was aroundone 5pm the evening I got the heater. The next morning the temp in my water had dropped from 76.6* to 74.2*. The thermometer is reading higher than actual water temp. If I turn the display/controlder to 80 it jumps right up to 80 and drops to 79 heats back up to 80 and so on..if I turn it to 91 it jumps to 91 in about 5 minutes while actual water temp is 76ish. Just not happy at all with the heater
  • Very impressed By Dave on 11/15/2016

    I have recently gotten back into the hobby after a long hiatus. I've had many tanks throughout the years and have found dual metal thermostats tend to fail on rather than off. I like the idea of a digital controller. I was a little skeptical buying this as I did so before there were any reviews on this, but it has turned out great. Also, much less expensive than a separate controller. This heater keeps the temperature to +/- .1 degree! I have an LCD thermometer with an alarm set to +/- 1 degree and have yet to have an alarm.
  • Good product, Worth the money By DavidTag on 11/2/2016

    I bought this heater after my cheap (not even sure of make/model anymore) saltwater heater broke. It is very easy to use and seems to have a pretty accurate thermostat. In my opinion the best part is that the heater controller does NOT lose the settings if unplugged. This is essential when using with a controller like Apex (what I use) which turns power on and off to equipment. I bought the 100W version and it does a good job keeping a constant temperature, even prior to me installing the Apex controller. The instructions say to mount it horizontally, I guess because of the location of the thermometer on the heating element, but I didn't have space so I mounted it vertically. that doesn't seem to make a major difference as long as it has steady flow (in sump where water flows constantly. The one con is that the cord isn't very long. Luckily I didn't need it to be.
