Fluval Electronic Heater, 200 Watt

I have been using it for approximately 2 months and it works great in my 80 gallon aquarium. I recommend this heater.

Awesome heater!! People say that it give you flase reading you have to have good water flow passing through the heater and positioning the heater horizontally I bought 3 and all 3 works perfect!!!

Excellent product. The temperature readout is very visible. The extra side mounting bracket is a nice option. The low flow detector is helpful to know if you need to reposition. I'm glad there is a cage to protect my fish from burns.

Love the heater but had three of them, two replaced because after around 6-8 months they cannot be raised or lowered and stay stuck on 79 Degrees. If you want to keep sending them back until Fluval fixes the flaw good luck.

Good heater if not for that constant LF error code. LF code appears even under the HOB filter output.

They worked great till now. Cant get them to change temp and now they arent working. I bought 3 and all have slowly stopped working. Also bought a E100 and it failed also. Thought I read up enough on these and they were supposed to be great. Get the warranty.

Received broken, Sent back, shows it was received, still no refund

I tried to use this to heat a 75g from ambient 65F to 80F, and it struggled a lot. It was only able to reach 76F even after letting it run for a few days and double-checking the temperature with other thermometers. My 250W Eheim Jager heater can heat the tank to 80F just fine, so I have to assume this heater is just not as capable.
