What's an accurate evaporation rate for the hour long boil?
Jun 20, 2015 · In Denver, Colorado, water will boil at about 94°C. Do not confuse boiling with cooking. Cooking pasta in Denver is a slower process because the water is at a lower temperature.

Does anyone know how many watts are needed to maintain a 5 or …
Feb 18, 2013 · To boil off a gallon of water in an hour it takes about 2,400 watts delivered (not counting that lost to heat transfer) for that hour. So if you lose ~750 watts through the kettle sides you will want a 3.15kW element. I run a 4.5kW element to boil 12.25 gallons down to ~10.70 gallons in an hour...which is on the high side for boiloff rate (12.7%).

Why I am losing so much water in boil? - Homebrew Talk
Feb 9, 2017 · The rate of water loss during the boil is proportional to the heat input. If you double the amount of heat going into the BK, you will double the boil-off rate. The total volume loss is the boil-off rate times the boil time. To lose less water, you need to lower the heat during boil. You need to learn your own system.
