So i have been thinking and searching if its possible to use office water cooler (heating/cooling one) as a main element of fermentation temperature control system, and i dont find much information. My idea is to use plastic bin big enough to fit 2 carboys/buckets, fill it with water, add water aquarium pump (or 2) and recirculate water through water cooler heating/cooling elements. Easiest way would be to setup water cooler above fermentation bin and let water (cold or hot) flow back by gravity force. One could imagine connecting temp control element and plugging two water pumps in to it (one for heating where recirculation goes through heating element and 2nd for cooling) but i dont know how to control valves, or use one pump and wire temp controller to open hot or cold spigot (have no idea if this is even possible, solenoid valve?).
Does anyone seen project like that, is it doable or its not worth to bother and i should get chest freezer (price, big footprint and small mobility of chest freezer make me look for alternatives)
