Troy.. It basically works as a heater but through the glass. It also does the reverse and cools. Hard to explain.. umm..

It is two electric plates mounted side by side.. when electricity passes through it in one direction it produces heat. When the current is reversed it cools. I am going to use this for heating and cooling the tank.

In essence it pulls the heat from the tank and releases it to the air. And does the reverse for heating. Voila a heater n chiller in one.. [img]images/smiles/icon_biggrin.gif[/img] I am actually suprised I have never seen one or heard of anyone using one like this.. Great application.

I was thinking about making these and patenting them(the controller) but heck.. I'll share.. Too much work right now to make it quietly.. lol

It is called a Peltier device. It is a Thermoelectric cooler/heater module. A good example of one of these is those car food coolers/heaters you can get from Canadian Tire.
