@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.
Types of heat pumps. The two main types of heat pumps are compression heat pumps and absorption heat pumps. Compression heat pumps always operate on mechanical energy (through electricity), while absorption heat pumps may also run on heat as an energy source (through electricity or burnable fuels).
