Room or zone heaters are heaters that are used to heat certain spaces or rooms. They concentrate heat to smaller areas, usually where the family spends the most time. It's not unusual for a home to have more than one zone heater. The purpose of zone heaters is to reduce the expense of heating the home and make some areas more comfortable, while those spaces not being used, remain cool.
