What is a furnace that can be installed in different configurations called?

A furnace that can be installed in different configurations is referred to as a multi-positional furnace. This type of furnace offers flexibility in installation options, allowing it to be placed in various orientations such as upflow, downflow, or horizontal. This adaptability is especially useful in different types of buildings and spaces where specific placement is required due to available space or ductwork configurations.

The versatility of multi-positional furnaces makes them suitable for a wide range of mechanical systems, helping to optimize heating efficiency and comfort levels in residential or commercial settings. Their design allows HVAC technicians to customize the system based on the unique needs of each installation, enhancing the effectiveness of the heating system overall.

While other types like multi-zoned or standard furnaces have their unique features, they do not necessarily emphasize the configurability aspect that is central to multi-positional furnaces. Similarly, adaptable furnaces might imply some level of flexibility, but the term "multi-positional" is the standard terminology used in the industry for devices explicitly designed to be installed in different configurations.
