Sorry Beemer, I don't keep detailed records, I brew for fun. My 4000w will bring 9 gal post sparge to a boil in 20-30 minutes or so. I used to wrap the kettle w/ a blanket, but lately I don't bother. I think the heat lost through steam is far greater than the uninsulated kettle. I would think 11kw will boil 18-19 easily???
