Back Heat in my 15 qt tub rack

[tsshields]

I just don't see where all the heats going, I mean your putting thin plastic against something thats 110 degrees and its coming through at 76? measure your heattape with the IR gun (btw guys IR means infrared not instant read), something just seems weird, i mean my house is at 70 degrees and my thermostats are all set around high 90's, low 100's

I will do a videos tomm morning and give all data and maybe we can come up with a conclusion if you dont mind checking it out and seeing if you could help thanks again and i will see what the tape is reading with the IR gun
