Abstract: A manifoldhead and expansion tank combination is provided. The manifoldhead comprises an outer housing having an inlet channel and an opposed outlet channel extending laterally from the manifoldhead and a connection means, surrounding a third opening from the outer housing, for sealably connecting the manifoldhead to the to the expansion tank. The manifoldhead further includes, secured internally within the outer housing, a baffle plate extending longitudinally within the manifoldhead and having an opening extending through the baffle plate, the opening being preferably aligned with the inlet and outlet channels. The baffle plate extending into AND through the third opening to continue to separate the flow moving through the entire expansion tank into inlet and outlet flows, entering and leaving the third opening. There is also preferably provided another set of baffles extending across the third opening limiting the inlet and outlet flows through the expansion tank.

Abstract: A switchable magnetic filter for collecting metallic particles in a fluid flowing through a vessel, comprising a handle for rotatably or slidingly engaging a magnetic assembly within a housing to an ON position to create a magnetic field outside of the housing to collect and retain metallic particles against the outer wall of the housing, and to an OFF position to shunt the magnetic field within the housing to release the metallic particles from the outer wall of the housing so they may be removed from the fluid for cleaning purposes.

Abstract: The invention generally relates to a heat exchanger. More particularly, the present invention relates to a heat exchanger configured for optimizing a percentage of heat exchange surface within an identified range of heat flux, or rate of heat energy transfer through a given surface, on a boiling curve.

Abstract: A method and system is provided for controlling efficiency of a heating system which is a combination hot water and space heating system that can modulate energy transfer. The heating system includes a heat exchanger for transferring and modulating heat between a primary fluid system having a hot water supply and a secondary fluid system for space heating. The primary fluid system includes a storage container, temperature sensors, a heating element connected to the heating assembly within the storage container for increasing the temperature of the storage fluid therein, a heating assembly, and a storage pump for delivering storage fluid from the storage container to the heat exchanger. The secondary fluid system includes a heating supply structure for containing a heating supply fluid, temperature sensors, and a heating supply pump in connection with the heating supply structure for circulating the heating supply fluid.
