In a heating system, what does the term "monoflow" refer to?

The term "monoflow" refers to a one-pipe circulation system used in heating applications. In this type of system, a single pipe is used to deliver hot water from the heating source to various heating elements, such as radiators or baseboards, and then return the cooled water back to the heating source. This design simplifies the plumbing layout and installation, as only one pipe is needed for both supply and return.

In a monoflow system, special devices known as monoflow tees may be used to allow for individual heating elements to draw hot water while still maintaining overall system balance. This ensures that each unit receives the necessary flow without the complexities associated with multi-pipe systems. The efficiency of heat distribution and ease of installation makes monoflow systems popular in residential and some commercial heating applications.
