I was stranded and needed a new heater so I put one of these in my LFS and the difference between turning the heater on and off was 4*F. I pulled it out and replaced it with asap an Eheim Jager as Smog. I will continue to use it as a flow heater, but I will no longer expose the animals to these extreme temperature fluctuations.
