Abstract
The invention relates to a heat emitter unit for a hot water heating system. The heat emitter unit is characterized by a valve and a heat emitter unit being integrated in a manner so that the valve casing and the heat emitter pipe to which fins are attached are in axial alignment. The heat emitter pipe has a central tube arrangement which provides in parallel a central bypass and a surrounding valve controlled passage. Heat from hot water flowing through the surrounding valve controlled passage is transferred through the finned pipe to the fins.
Claims3
A heat emitter unit for a hot water heating system, comprising, a valve section having a casing, a heat emitter section including a pipe section and fin means attached to said pipe section, means connecting said valve and pipe sections, partition means for said valve casing having a bypass opening and a valve seat opening, centrally disposed tube means forming a central passage and an annular passage, said tube means extending from said bypass opening to a point generally aligned with the downstream side of said fin means, and controllable closure means for cooperation with said valve seat opening to control the flow of fluid through said passage.
