Hi,
I did a hot water test of my cooler with aprox 18L. The water had an initial temperature of 71.3'C which sunk to 65.5'C in 70 minutes. I did not preheat the cooler but let it approach equilibrium for about 5 minutes before taking the temperature. The temperature sunk from 65.5'C to 61.6'C during the next 70 minutes. I placed a blanket on top of the lid for better insulation. Using the last measurement that equals a loss of about 3.3'C or 6'F per hour.
Is this heat loss acceptable for a mash tun?
18L ~ 19 quarts
71.3'C ~ 160'F
65.5'C ~ 149'F
61.6'C ~ 142'F
