Re: Heater Rant
I have had two visi-therm 200 watt units fully submerged for about 7-8
years now, with no problems.... One of them actually cooked for a while
after I did a water change and had it running with no water. After cooling
it off with a fan (BTW, the sizzling sounds when I started filling the tank
tipped me off that something was wrong :-{) and refilling the tank I got
another 4 years or so out of it. It actually just died late last year, due
to a failure of a crimp connection between the element and the connections
on the control assembly inside the glass tube.
Basically: install them any way you want, they'll work fine, just keep them
in the water! :-).
