there is a drain at the bottom of the coil in case it makes water also a drain to empty the barrel. my well water is around 50 degrees . the air is regulated entering the coil so very little flow . i only run 10-15 lbs through the hood. on days i use it i will fill it the dump ice in it right before i start. cool your head and neck your body wont know it's hot .
i plan to wrap it with foil insulation i have laying around . country boy country ways .
