Abstract (en)
[origin: EP2629019A1] The unit has two heating circuits provided for room heating and domestic water heating, respectively. A pump housing (26) has a suction-side chamber (29) into which two return lines (12, 13) open. The return lines are closed off towards a suction side of a pump by a switching unit. The return lines comprise an angle (alpha) between 60 and 120 degrees in an area of a passage through a chamber wall. Horizontal and vertical pipe sections (31, 32) are arranged perpendicular to each other, and connections for the return lines are formed at the housing, where the switching unit has a lever (34). The pump housing is designed as a plastic injection molding part.
