Heating Problems--

Im having some major heating issues (at least i think they are).

I use a visitherm heater--i think 50 watt in my 5 gallon nano and i get major over heating and temp swings--is there any way to combat this? and does anyone else have similar problems?

i have it calibrated to about 78 degrees but in midday--my temp reading in like 84.9 degrees F. How can this be? I have a raised light fixture and decent air movement over the tank, yet im getting this dangerous temp reading.

And when I checked it today at about 12:30, the reading was that high (84.9), the heater was calibrated to 78 degrees, and the thing was still running!...what is going on here???


thanks for the help

cheers,

Sounds like your heater could be stuck on. What are the temperatures like with no heater?

In my opinion a vast majority of heaters on the market are crap. I've had 2 separate incidents of sever overheating killing a lot of my livestock. Best way to test is to just take out the heater. I live in Texas so this is easy for me to say, your house may be considerably cooler, but right now mine is 80 . I believe that there are some external failsafes for heaters. Also, i have yet to have a problem with an ebo jago heater, so maybe its the brand that makes the difference.

The rule of thumb I go by is 5 watts for every gallon. If you can find a heater half that size, you should look into it.

If the room isn't too cold you may have success with one of the small preset heaters like this one: Mini Heater

I've used them in 5G tanks in conjunction with lights before to maintain a reasonable temperature.

These do have a very low wattage though so if the room will be below 70 degrees or drafty this wouldn't be the best choice.

i just dont understand why the heater is running when the temperature of the water is CLEARLY above the calibrated temp...it really makes me angry becuase I think thats what melted my Riccia F.

I use other visitherms and dont have the same problem though. Its not that the heater stays on All the time, becuase it doesnt. Its just going above and beyond what I want it too--its frustrating beyond annoyance.

I wish the producers of these products would actually put some technical knowhow into their crap--then people wouldnt have these problems.

If its possible to climately control a sports complex super dome, and have very few fluctuating temperature variences, Then why cant someone come up with a reliable water heater to keep the most stable compund known to man (H2O) at a constant temp???

arghhhhh--negative cheers,
