So I got a piece of flex on a 2-41qt tubs and a 32qt tub. The first 41qy said 93 on the floor. The second one said 90. The last one said 85.

All same size flex. All tubs same height off the floor.

Checked with acurites in each tub. The one burning hotter at 93 is brand new. The other two are a tad older. Maybe a few months.

I don't know what's going on. Are the thermometers off? Or does flexwatt have a burn in period?
