Brewing an extract Chinook IPA a few days ago. I brought the 2.5 gallons of water up to 150°F and added the steeping grains. Did some supper preparations and came back to the kettle a half hour later. Rinsed the grains and turned the heat to high for the boil. Half hour later no boil. Lifted the kettle. Only three of the center coil rings were red hot. Used tongs to pull the warm coil and replaced with the coil from the large back burner. Boiling in three minutes.
The front burner does all the high temperature and large kettle cooking. I guess 10.5 years of hard work isn’t too bad before needing replacing this coil.
