👉 A furnace is a device that provides heat to a space or environment. It is typically used in residential and commercial settings, such as homes, businesses, and industrial facilities, for heating and cooling purposes. In the context of furnaces, they are often referred to as "heaters" or "boilers," although the term "furnace" can also be used interchangeably with "boiler" when referring specifically to a type of furnace that is designed for heating and cooling applications.
