Anyone using a HERMS system? I am building a new heat exchanger in a smaller (2 gal) Rubbermaid cooler. I'm using a copper coil and heat stick mounted thru the lid. Basically I circulate the beer thru the coil which is immersed in a temp controlled water bath. I need to circulate the water to even out the temperature but space on the top of the lid is precious and offers little room for a motorized unit.
My question is has anyone used these little submersible water pumps they use in decorative fountains to circulate water? I tested one out and it seemed to work great but I'm not convinced it will hold up to contant 160 degree temps.
