  • the present invention relates to a distributor device for water and a heating installation for a building, comprising such a distributor device.
  • a modern heating installation can be considered as an assembly of sub-installations, each with a flow pipe and a return pipe, which in the desired way need to be connected to each other, both hydraulically and in relation to control technology.
  • Said sub-installations are for example a combustion boiler, a heat pump device supplying heated or cooled water, an installation for heating water by means of solar collectors, a buffer tank for heat or cold in the form of heated or cooled water, a boiler tank for sanitary hot water, a heating circuit for floor heating, a heating circuit with radiators and/or convectors, etc.
  • Said sub-installations have their own characteristics with regard to the temperature of the supplied or required hot water, the desired operating times and time-dependent energy cost.
  • the integration thereof requires a large number of pipes and connections and a high level of automation.
  • the invention relates to a distributor device for water, whereby the distributor device comprises a manifold, whereby the manifold comprises a first collector cavity, a second collector cavity and a third collector cavity, whereby the manifold comprises connection points for connecting a pipe or a pump to an aforementioned collector cavity, whereby the connection points comprise first connection points for connecting a pipe or a pump to the first collector cavity, whereby the connection points comprise second connection points for connecting a pipe or a pump to the second collector cavity, whereby the connection points comprise third connection points for connecting a pipe or a pump to the third collector cavity, whereby the manifold comprises two or more first connection points, whereby the manifold comprises three or more second connection points, whereby the manifold comprises three or more third connection points.
  • the manifold comprises four or more third connection points. In a more preferred embodiment the manifold comprises five or more third connection points.
  • connection points on the manifold can be provided with indications that indicate, with or without the use of a legend or manual, which pipe of which sub-installation must or may be connected to a specific connection point by the installer.
  • Such distributor device can also be used universally for a large variety of heating installations.
  • the manifold is made from one piece, or in other words the manifold is single-piece. This reduces the risk of leakages.

Optionally, the relevant control valve 3 can be removed and replaced by such cap.
