- HMA-S Heater w/ Analog Controller - Finnex
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 HMA-S heater is virtually unbreakable unlike glass heaters and are corrosion resistant.
All HMA-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.
Finnex HMA-S heaters come with an attached analog 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 HMA-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.

Must mount horizontally By Joseph on 5/1/2020Joseph wouldn't recommend this product to a friendI primary ordered the 50w version for it's small form factor to go in the back of my biocube 12. To my disappointment the instructions say to mount it horizontally. So now I have a heater in the display part of my AIO. The thermostat seems to be accurate, but the pumps, lights, and room temp keep the tank at 80. So the heater will be set at 77 for tank stability. I'll update after some use, but if you need a small heater for your all in one, keep looking.
Waste of money By Luke on 7/12/2019Luke wouldn't recommend this product to a friendDoes not hold temp. Keeps a 4.5 degree temp swing from 75.5 a 80. Would not buy again.
Update to "Works out of the box" By William on 5/15/2019William wouldn't recommend this product to a friendI've had it for almost precisely three months and it has failed. Will no longer hold temperature. It still gets warm, but not warm enough. At least it did not fail "on." To be fair, we worked it hard, often turning the house heat way down at night. It always was very accurate.
Works out of box By William on 2/17/2019William would recommend this product to a friendI'll write a follow up review in 6 mo to a year, but, out of the box, I stuck it in the sump, plugged it in, and set the temp. 300 w version in a 65g and 20g sump. Warmed up to 78 and holds quite steady in a room that gets down to low 60's at night. 4 stars bc cord is stupid short after controller.
Product needs to go back to R & D By Christopher H on 2/11/2019Christopher H wouldn't recommend this product to a friendHeater is some what reliable to when using a third party controller. By its self it is can be off as + or - 6 degrees. it is a little disappointing though when you have a brand new heater not even a week old explode, and no it wasn't run dry. Hopefully the other three 500watt heaters I have last more than 6 months.
Fine with an apex By Kwikkatxr7 on 2/8/2019Kwikkatxr7 would recommend this product to a friendIt works fine with an apex, I just had to set the thermostat on two of these units to 88 to keep my tank at 78. This was the Hma-s 300. But for the price I can’t complain too much. watt.
hma-s heater w/ analog controller-finnex By Chuck on 2/1/2018Chuck would recommend this product to a friendI like this company for their heaters, I have used Finnex before on several other heaters. I like the digital units the best.
Decent By Cherub on 10/4/2017Cherub would recommend this product to a friendThis was a decent buy but the cable is very short. I was surprised how short it actually was. I don't know about it being off a few degrees or not as other mentioned. I use a controller with temp probe to control the temp. It is a pretty loud click when it turns on. Overall I would recommend this. Buying a second one as a back up.
Just ok. By Carson on 10/1/2017Carson wouldn't recommend this product to a friendHas a loud click when turns on, Heater temp is -4 degrees F off from two separate probes. Using the 150 watt in a 43 gallon. 78 F tank temp, ambient temp off 76.
Great heater By Nicholas on 7/17/2017Nicholas would recommend this product to a friendI have used this for a few months now and it was very accurate right out the box set at 77 and keeps tank at 78 F with almost no swing even when measured throughout the day with an external probe. The guard is nice as well, I have a red hawk fish that loves to perch on everything, and it protects him
Good Heater With a poor self thermometer By Andy on 11/28/2016Andy would recommend this product to a friendI have the 300 watt version of this heater. It is very stable and does a good job heating my 75 gallon reef tank. However, I had to set the temperature up to 81 degrees so that I could get it up to around 78 degrees where I like to keep my tank. Glad I have my tank controller to keep the truth about the real temperature.
Will this controller keep its last set temperature if power is cut? I'm looking to use two of these as suggested in the BRS series. I am looking to tie two to my APEX, and set this temp controller a degree higher than the APEX is set to for redundancy.
This will keep the temp recorded even when unplugged. Feel free to let us know if you have any further questions!
Does the controller have the capability to turn the heater on and off after programming a set degree. For me, this heater will need to interface with my chiller so the two components do not fight against one another.
This heater will be able to control itself to turn on or off if above or below the set temperature. Feel free to let us know if you have any further questions!
Will this heater function accurately in the horizontal position, as in flat on a sump bottom where the flow from a baffle will move directly over it?
Have a great day!
