I think these heaters are underpowered. They can't keep my 55 gal warm so I put in another heater and it's been pretty stable. I loved this heater in my 20gal as it kept the tank at exactly 78 degrees. No more no less.
I think the on off cycling is to allow the heat to evenly distribute before it heats again.

As I said I believe it is the internal temperature sensor that inhibits the `heat cycle` if too warm and it appears that unless youhave a really good water flow through the heater ( or the tank demands are really low) it will only `heatup` for approx 30% of the time that it should be heating.
Here is a youtube video; from Fluva/ I believe, extolling the virtues of the E-300 series.
LED
, this is FAR TOO HIGH.....In this day and age of being GREEN this is unacceptable.

Just got a reply from Hagen/Fluval
New Message

Dear Mr XXX
Thank you for your e-mail.
The E heater may have need to be reset, to do this turn off the heater and re-position the heater on a 45 degree angle, then turn on the heater and turn down the temp as low as it will go,18" ,then turn up the heater as high as it will go ,34" ,after this set the heater at the desired temp and leave at a 45 degree angle making sure it is totaly submerged.
We have had no problems with the heaters,the only issue we have had, is that the heaters need to be positioned on a 45 degree angle to disperse the heat .The heater are so sensitive, they will sometimes read the water temp inside the heater guard if positioned verticaly.
If non or the above helps please call me or return it,along with your proof of purchase to your supplier for replacement under warranty,as it has a 5 year warranty with them.
Hope this helps

I have one in my 50g freshwater for over a year and works great. I can even test it against other thermometers and it's accurate. Just bought one for my 55g saltwater and it heated the water in about an hour and has stayed a constant temperature.
