Lets be scientist for a while! I ran an experiment to calculate the energy that the water gets over time, and from this to calculate the power of the water cooler that i need to have in order to keep the water cool. The method and the results are extremely interesting, but also extremely disappointing... I need to increase efficiency dramatically otherwise my Heating Folder will require more energy to operate than a power drill...

I know that the water will get hot. I know that i have to have a means of cooling to avoid overheat. What i don't know, is how powerful this cooler must be. There are 2 ways: The first one is to get some peltiers and run some tests... But i prefer the second one which is more scientific. I can run a test without a cooler and calculate the amount of energy that the water got, and thus calculate the power of the cooler. So, hands on workbench:
