Hey everyone, I just took some measurements on the power of my stove, and I did a little reading about BTUs on wikipedia. I wanted to measure the effective BTUs of my kettle & kitchen stove top. Let me know if my calculations are off. Has anyone else taken these measurements? What were the results & what's your setup?
My setup:
Kitchen stove, 2 burners (kettle straddles the two)
7.5 gallon stainless kettle (14" diam, 12" height); the sides are really thin
Heating up water with kettle lid OFF:
Start temp: 141F
End temp: 168F
Change in temp: 27F
Time: 7 min
Gallons of water: 3
Pounds of water: 25
BTUs: 25 * 27 = 675
BTUs/min = 96.4
BTUs/hour = 5785
Heating up water with kettle lid ON:
Start temp: 134F
End temp: 192F
Change in temp: 58
Time: 20 min
Gallons of water: 5
Pounds of water: 41.65
BTUs: 41.65 * 58 = 2415.7
BTUs/min = 120.8
BTUs/hour = 7247
