in the section of flame on the iron forum

Friends, help me with advice.
Everyone knows that for the best transfer of heat from the processor to the refrigerator, the touching surfaces should be flat, smooth and even polished to mirror gloss, as well as they should be slightly lubricated with thermopasta. I have an electric plate in the kitchen, and its shapes are not only not smooth, they are noticeably ribbed, round waves from the center to the edges. The days of the pot and bowl are also far from a flat surface, not to mention mirroring.
Do you think it makes sense to align clothes and dishes? What if you use a thermometer? The electric plate heats significantly longer than the gas, probably three to four times. Probably there are big losses.
And also the popular question - why do the electrical plates make so ribbed?
