The new definition of Smart, Safe & Stable heating.

The Helio line from Innovative Marine are a new line of aquarium heaters utilizing advanced PTC (positive temperature coefficient) technology to exceed current reef aquarium heater standards for improved safety and reliability. Unlike traditional heating elements that utilize resistance wires to generate heat, the Helio heaters were developed utilizing PTC technology from the aquaculture industry, which relies on solid-state ceramic chips that are programmed to reach a predetermined temperature. Thanks to these smart ceramic chips, the heaters are naturally resistant to overheating, and the PTC smart controller continually communicates with and monitors the heating elements to maintain a stable temperature.



  • Corrosion resistant PTC titanium element
  • Titanium remote sensor
  • Magnetic sensor holder
  • Magnetic heating element holder
  • Fast warm up with low surface temperature
  • Solid State Ceramic Chips regulate heat
  • Long Life, energy efficient
  • Audible Alarm
  • 5 Year manufacturer warranty


Each piece of the Helio heating system was created to work together. The PTC smart controller has been fitted with a titanium remote temperature sensor and dual heating element power lines. Since each heating element has its own built in temperature regulation system, there’s safety in redundancy from the controller’s temperature sensor. And if dual heating elements are employed, there is yet another level of safety added to the system. Commercial grade titanium heating sheaths and screws prevent corrosion. Rare earth magnetic heating element holders allow optimal water flow. Quick disconnects for the controller’s temperature sensors and heating elements make for easy maintenance and upgradeability.

Product Questions

Does it work on UK 240V power ?
Question by: anoop on Dec 18, 2023, 12:28 AM
Hey there, These will have the plug to work on 110v if you are looking for a 240v version I would suggest to reach out to IM on that. Thanks!
Answer by: Codey on Jan 8, 2024, 2:13 PM
I want a 400 watt (dual element) but I don’t see the option to purchase this combo. If I but a 200 watt single and an extra 200 watt element do I also need to purchase the magnetic holder? I can’t see any info if the element comes with a magnetic holder or if the controller comes with two holders.
Question by: Colby Debolt on Dec 3, 2023, 12:11 PM
We unfortunately do not carry the 400 watt dual element. For the 200 watt single, you would need to purchase an additional magnetic holder.

Can this heater be used for freshwater ?
Question by: Brandon on Feb 4, 2023, 6:56 PM
Yes, this will function in freshwater!

According to the manual on IM's website, the Helio controller is the same Item Code for all wattages (item 830001). If that's the case,
(1) can I buy a single-element kit now and then buy a second element later?
(2) can I run 2 different elements, e.g. 100W (830003) & 200W (830004), together on the same controller?
Question by: Michael Arko on Nov 3, 2022, 9:58 AM
Heating elements can be purchased separately but the same wattage for each element should be used on a single controller.
Answer by: Scott F. (BRS Staff) on Nov 9, 2022, 1:20 PM
Can u buy just another heating element? As I already got a 350 and just need another 350.
Question by: Sven Pflug on Oct 19, 2022, 2:46 AM
How long are the wires from the heater to the controller? Wonder if I put controller on board outside the cabinet are cords long enough to reach into sump , thanks
Question by: Joseph Castro on May 22, 2022, 11:41 AM
The cord length between the Helio controller and heating element is either 4 foot or 8 foot depending upon the wattage of the element.

Can i use the BRS titanium heating element as a second element for the Helio PTC?
Question by: Jeff on Jan 12, 2022, 7:20 PM
Unfortunately, you cannot. The Helios does not use standard power outlets.
