Innovative MarineHelio PTC Smart Reef Aquarium Heater (200 Watt - [2 x 100W])

This replaced a pair of heaters in my 14 gallon AIO reef tank. Those were glass heaters and continually became encrusted with sponges, raising a risk of cracking. Needless to say, this titanium heater has no risk of cracking.Good:Magnetic mounts for heaters and sensor with plenty of strength to hold in place.Heater mount holds element 1.5" from aquarium wall for maximum flow and eliminating cracking risk.Cables from the controller are about 8 feet long, plenty of length to mount anywhere you want.Easy to set up and use -- took about 60 seconds. High and low alarm set points easy-peasy.Temperature sensor is spot on (double checked with infrared sensor).Display clearly shows tank temperature and set point.Not so good:The temperature sensor has a low flow alarm, which is a very nice addition. However, the alarm goes off when I pause the return pump for feeding or water changes. The only way to stop this is a manual switch on the side of the controller, which disables all alarms. This introduces a risk if one forgets to turn the alarm switch back on after performing tank maintenance.The controller really should have an alarm pause button (~ 10 minutes) to eliminate this risk.All in all, the best heater I've ever used.

Yes, this device is an enormous extravagance in a fish tank… but it’s amazing.I’ve had quite a few tanks in my day. I’m no master of fish, but on and off for 40 years. Saltwater and fresh.Number one thing I hate is junk heaters. They don’t last, they’re hard to set, they produce large temperature fluctuations that change by the day, etc etc.This device eliminates all those problems.I put it in a brand new 60gallon cube with no fish. Starting water temp was 72.About 2 1/2 hours later (dual 200w version) the temp hit my setting of 77.0.It has literally not moved 0.1dg since.I’ve tested the water temp with digital meat thermometers and a no-contact infrared thermometer too. All agree to within the decimal point. 77.0 on the nose. Honestly, it’s surprising the thermometers all agree more than that the temp is perfect.In any case, this is a worthy investment. Yeah, it’s bonkers expensive for an aquarium heater… but think about it.You e probably got several hundred invested in other equipment and might have several hundred more in fish.Spend $250 and get a good heater.Stop wasting $30 every few months on junk.

I was completely surprised by the weight of the package. I didn't think it was the correct item at 1st. Then I unpacked it, speaking of the packaging it is amazing, everything was in a separate box that fit perfectly into the main box. Most of the The weight comes from the magnetitic holders. Setting up is really easy, it is very much plug and play. I still need to calibrate it , but we needed to get it into tank as soon as possible as our backup heater just failed. I hope that this unit last , as we have gone thru several heaters in the past few years.

This is a great heater and after a month of use it holds its accuracy very well. A lot of major catastrophic failures are from tank heaters. This unit is expensive, but when compared to the overall cost of a reef, or salt water tank crashing due to a faulty heater it is money well spent. I recommend this unit.

Set it and forget it. All my temp issues are now solved 5 stars +.

I can't add anything anyone else has mentioned other than the magnetic mounts are..lousy. I have a 400+ liter tank with 12/13mm glass and these magnet mounts barely hold anything in place.

Overall it seems very high quality thus far. Easy to use. Pricey but a great product.

I bought two of the 1000 watt models. They have two heating elements each. After about 6 months one of the elements keep throwing a code. Contact customer service they say to move to a high flow area in tank, still throws code. Next they tell me to clean it , still same problem it’s only 6 months old. So far the other 3 are ok, I won’t buy these heaters again.2-12-24 update the other overpriced heater shows a code, it lasted almost a year. TRASH, dont wast your money!
