<p>Compact heating system with two heating circuits, one for room heating and one for hot water production, comprises a primary heat exchanger, a secondary heat exchanger for hot water production, and a rotary pump (1) conveying a heat transfer medium through the primary heat exchanger and then through one of the heating circuits. A distributing valve (2) connects, depending on the switch position, one of the heating circuits to a circuit with the primary heat changer. The rotary pump and the distributing valve are arranged as a construction unit on the hot side of the primary heat exchanger. The pressure joints (5) of the pump are directly joined to the adjacent valve housing (6). Preferred Features: The pump housing (4) is made in one piece with the valve housing of the distributing valve.</p> |
