Micro Water Heater/Cooler Answered
The title says it all!
I'm looking for a small enough unit to carry (under five pounds, optimally), that can either heat or cool any liquids passing through it. I was initially considering cooling plates, but that requires an extra pump and more equipment, which kind of brings me over my weight total.
It's also perfectly fine if both units are separate, as long as I manage to get my hands on something I can use.
