There are those fixed heating units that supply heat to your entire home and then there are those portable heaters that can be carried from room to room for localized heating. The portable option may be more for a heating addition for a specific room, rather than the only heating source, like a milkhouse portable heater. These are commonly used in bathrooms, porches, and office cubicles. They provide a nice localized heating source, but are not intended to heat the whole room.
