@andreadrhodus I think the grade is a general grade not only for the dieting part, they include the benefits such as the vitamins and so, 360 for medium fries is not that bad since we are allow to eat around 1900 or 2000 a day.
A variety of technologies are available for heating your house. In addition to furnaces and boilers, heating options include wood and pellet heaters, active solar heating, and heat pumps, which are used for both heating and cooling.
A heater coil is a device used to heat water or air. Typically electric, the heater coil acts like a large resistor, and as the electric current flows through it, it begins to heat up. The resistance wire used in common household toasters is the same type of wire used in a heater coil. The amount of heat produced by the heater coil is controlled by a rheostat switch. Many appliances, such as hot water heaters, electric clothes dryers and electric ovens, all use some type of heater coil to produce heat.
