Answer to Question 1

Aquastat controls are used for hot water oil fired furnaces. They maintain the furnace water at the proper temperature. There is a high limit setting and a low limit setting. The high limit will shut off the burner at a preset temperature.
When the water temperature reaches the low limit, the burner will start up again so that the water temperature does not drop too low.

Answer to Question 2

The disconnect should be sized at 115 of the minimum circuit ampacity 1.15 x 31.5 = 36.225 since disconnect sizes jump from 30 amps to 60 amps, a 60 amp disconnect will be needed.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
