Gas dryers run their motor, controls and ignition on an ordinary receptacle, while electric models need a dedicated two-pole circuit.

Changing between three and four conductor cords requires reconfiguring the jumper inside the appliance, or the frame ends up energized.

Splitting cooking into two appliances usually means two circuits, two sets of instructions and two accessible connection points.

Adding the wattage of every element and the oven together gives a number no kitchen ever draws, which is why demand factors exist.

Delaying when a tank heats does not reduce how much water you use, so most of the promised savings never arrive.

The efficiency comes from moving heat out of surrounding air, which means the appliance cools and dries the space around it.

Heating water instantly requires far more power than heating it slowly, which usually means new circuits and sometimes a bigger service.

A storage tank is a continuous load on its own two-pole circuit, and borrowing a nearby dryer or range outlet is not an option.

Heating elements depend on surrounding water to carry heat away, so a few seconds without it destroys the sheath permanently.

That button is an over-temperature cutout, and every time it trips it is reporting that the tank got dangerously hot.
