Abstract

A method and apparatus for regulating the flow and the temperature in a central heating installation including a heating circuit having a feed pipe (28), one inlet control and distributing unit (38), a plurality of heating coils (40, 40', 40'), one collecting unit (42) and a return pipe (24) with a circulation pump (25). The unit (38) comprises an inlet chamber (44) with an outlet for the respective coil, valves (46, 46', 46') for temperature control, one mixing chamber (48) with inlet tubes (58, 58', 58') from the inlet chamber (44) and outlet tubes (60, 60', 60') to the respective coils with temperature transmitters (50, 50', 50'). The inlet tubes project into the outlet tubes with intermediate gaps (61). From the return pipe a portion of the return water is recirculated to the mixing chamber (48) and via the gaps (61) into the outlet tubes.
