Giacomini Hot and Cold Water Distribution System
The type of cold and hot water system may vary based on the building where it is installed and the type of application. For a single-family house, “individual” distribution systems are the most popular, where DHW production and distribution are carried out inside the dwelling unit. As for multi-family dwellings, office buildings, sport centers, etc., “collective” distribution systems are generally used with centralized DHW production. It is not uncommon to combine both types.
- Manifold installations:
• Connection To Single Inlet Units.
The manifold hydraulic system provides for installation of a distribution element (hydraulic manifold) in a special wall-mount cabinet which supplies all draw-off points of the hydraulic system. All draw-off points, both for hot and cold water, are connected individually to the manifold which is equipped with an interception valve for every single outlet. In this specific case, connection to the sanitary elements is obtained by using terminals (elbows with wall mount bracket) with a single inlet. Water flows through the single pipe only when the draw-off point collects it. The major benefit of this type of hydraulic system is the installation of whole pipes, i.e. in-wall connection-free pipes. In fact, the only featured connections are inside the cabinet where the manifold is installed and at the terminal.
- Connection To Single + Double Inlet Units
This specific type of manifold system also requires using double inlet terminals (elbows with wall-mount bracket) for connection to hot-water elements: in case of draw-off points with high water flow rates (e.g. Jacuzzi tubs, large shower heads, etc.), the manifold and draw-off point are connected through two pipes. All usage points, both for hot and cold water, are connected to the manifold separately. The water required by a draw-off point with high f low rates runs through both connection pipes and, in any case, only upon collection from the draw-off point.
• Closed-Loop Connection
The manifold hydraulic system with closed-loop connection provides for connection of all draw-off points through double inlet terminals (elbow fittings with wall-mount bracket). This guarantee, for all connected draw-off points, high flow rates. In addition, it drastically limits the risk of bacterial proliferation as water f lows through all feed pipes, even for unused draw-off points.
