It differs from property insurance in that a property insurance policy only covers the physical damage to the business, while the additional coverage allotted by the business interruption policy covers the profits that would have been earned.
Definition of forced air Forced air heating refers to room-level or floor-level heating which is distributed by fans next to electric coils that radiate heat. It does not apply to fuel-generated heat which is forced through ducts into various rooms.
Forced convection may happen by natural means, such as when the heat of a fire causes expansion of air and bulk air flow by this means. In microgravity, such flow (which happens in all directions) along with diffusion is the only means by which fires are able to draw in fresh oxygen to maintain themselves.
