Zone heating is the practice of warming the rooms in which you spend the most time, rather than trying to heat the whole house equally. This can be done efficiently by supplementing your central heat source with a gas, wood, or pellet burning appliance, either free-standing or insert. In any case, the result is a reduction in energy consumption.
A zone is an area of a house with independent heating and/or cooling control. Zoning segments the house into particular areas that can be individually controlled efficiently using a Multi-Zone Heating Controller.
