Header
A header is an important component in heating and cooling systems that connects multiple pipes together, similar to how a power strip lets you plug in many electrical devices. In heating systems, headers (sometimes called manifolds) help distribute hot water or steam to different zones or rooms in a building. Think of it like a central hub that takes the main supply of heated water and directs it to where it needs to go, making sure heat is distributed evenly throughout a building.
