Best Silent Internal Heater

[Ch4rlie]

Me too!
 
To be honest, I actually like it as it has a display on the LCD with temperature and goes blue if too cool and green being desired temp within a degree or 2 either way and red if too hot, this is good for at a glance checks of temp.
 
I did have a heater in the past with no LCD and just a fiddly dial with no numbers and had to keep checking thermometer on glass to be sure temp was ok, found this annoying as temp fluctuated sometimes.

I've only used cheap heaters so can't really recommend anything fancy. I had a marina heater that failed/kept overheating the tank and I replaced it with a no-brand heater that has been working great for over a year. My Tetra 300W has been working fine(and very silent) for 21 months so far, but I hate the dial it has, although according to my digital thermometers it heats the water to what the dial is setup to do, so not bad as most aren't accurate like that at all. 
I guess if it's internal heater, an option is to look maybe at titanium heaters or similar models which can't bust or burn the fish although I have never had a burned fish from any type of heater so not sure if that matters that much.
I've never had a Hagen E but thought of buying one at some stage, but they do have their problems too from what I read at the time, so research each brand is best. Measuring temperature is great with a decent digital thermometer. Same as heaters, some cheapo digitals don't show accurate temperature(my Juwel underwater digital thermometer is useless when it comes to accuracy)

I have heard of fish being burned on heaters, mainly plecos!
 
But you are right though, best to do research and come to your own conclusions.
 
I got my E Heater free since I prescribed to a years subscription to PFK and heater was a freebie. I read PFK anyway so win win for me really

Yeah, I know, I keep reading those stories but I question them. Why would a healthy fish stay next to a heater for long enough to get burned?...Stressed/sick fish in general hide behind a heater/filter, especially if there isn't much other decor so they may not have been feeling well to start with in those scenarios. I am not saying it's not a possibility and a weakened fish hiding behind the heater won't get burned with a proper heater guard or such, but the poor thing must have been way more terrified of something else if it chose to burn itself instead.

Certainly could be the case of stress or anxiety.
 
Your comment about lack of decor could be the case thats making them stressed or anxious.
 
Lack of bogwood caves or loads of live plants, lack of things like that may make them hide behind heaters?
