  2. Hydronics - Wikipedia

    en.wikipedia.org/wiki/Hydronics

    The two-pipe reverse return configuration which is sometimes called 'the three-pipe system' is different from the two-pipe system in the way that water returns to the boiler. In a two-pipe system, once the water has left the first radiator, it returns to the boiler to be reheated, and so with the second and third etc.

  3. Hydronic balancing - Wikipedia

    en.wikipedia.org/wiki/Hydronic_balancing

    Hydronic balancing, also called hydraulic balancing, is the process of optimizing the distribution of water in a building's hydronic heating or cooling system by equalizing the system pressure. In a balanced system every radiator is set to receive the proper amount of fluid in order to provide the intended indoor climate at optimum energy ...

  4. Water distribution system - Wikipedia

    en.wikipedia.org/wiki/Water_distribution_system

    An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2]. A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.

  5. Testing, adjusting, balancing - Wikipedia

    en.wikipedia.org/wiki/Testing,_adjusting,_balancing

    Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified design airflow or water flow. When beginning the balance of a system, you must locate the terminal with the least amount of flow in regards to the engineer's drawing.

  6. Boiler blowdown - Wikipedia

    en.wikipedia.org/wiki/Boiler_blowdown

    There are two types of surface blowdown fittings. The simpler is a pipe entering the steam drum at the normal water level. A more sophisticated skimmer arrangement attaches a swivel joint to the pipe for a short length of pipe suspended by a float. [2] The skimmer may be more effective at removing floating oil which might otherwise cause foaming.

  7. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.

  8. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main ...

  9. Plumbing - Wikipedia

    en.wikipedia.org/wiki/Plumbing

    In addition to lengths of pipe or tubing, pipe fittings such as valves, elbows, tees, and unions. are used in plumbing systems. [40] Pipe and fittings are held in place with pipe hangers and strapping. Plumbing fixtures are exchangeable devices that use water and can be connected to a building's plumbing system. They are considered to be ...
