ABSTRACT:
A hydronic multi-zone heating system mounts circulators for circulating liquid between the boiler and the zone so that all components are mounted in a common area for ease of maintenance and repair, as well as for convenient installation. Air removal is also provided from the system in a simple manner by providing an enlarged header that extends generally horizontally, and has supply pipes with open ends disposed well into the interior of the header, and below the level of liquid in the header during operation. An air vent is connected to a top portion of the header to effect removal of air that may collect. A variety of other system components, such as temperature probes, are connected to fittings extending from the header. Return pipes may also be connected to the header, and an interior wall within the header may separate the inlet from the outlet thereof, or there may be free communication. A primary circulator connected between the header outlet and the boiler may be supported by the header by cooperative mounting rings formed on the header and the primary circulator.
