An open hot water supply system uses water resources directly from heating networks, taking them to prepare and supply to the structure of hot water support for ordinary consumers. In such heat supply systems, water resources are taken, usually directly from the sections of the thermal city system.
Pros and cons of an open hot water system
Structural systems of heated water support are divided into:
Centralized. The unified water heating system serves at least one municipal or residential building, and in many cases even a certain, a certain number of buildings located within the limits within the border of one quarter (district) or a small settlement.
Decentralized. The preparation and supply of heated liquid, tap water, occurs near water collapsible devices (at the site of direct consumption) and is usually produced by small heat generators: gas burners, wooden columns and the like equipment.
Separation into classes of hot water support systems:
By the location of the feed (wiring) of the main supplying lines inside the residential structure:
Structural systems with the upper arrangement of the wiring;
Wiring up at the top is the most widely used when installing open (highly) tanks-drives and in the presence of the upper technological hall in the building, or the attic room. The cyclic line is installed in this case in the basements, and in their absence in underground, accumulative channels.
Nuances of an open hot water supply system
Structural systems with the lower arrangement of the wiring.
When the basements located in the building, it is more advisable to use the lower wiring as the most convenient for further operational maintenance of the entire water supply system.
The non -cycling structure of water supply is the simplest of the device and cheap, judging by its initial cost. Include a large number of tubular fluid conductors in their composition. The main disadvantage of such structures is to defend water in pipelines and, as a result, its rapid cooling.
The circulation structure of water support is used where the uninterrupted support of residents with hot liquid is required (residential buildings, hospital complexes, clinic and the like). In such structures, in the absence of a water analysis, the liquid, which is in the tubes, does not stop, but is continuously circulating, passing through the heating element, which ensures the pre -set liquid temperature near the points of the water distribution.
