2. Automatic bleeding valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_bleeding_valve

   The appropriate cure here though is the use of a chemical inhibitor, rather than continual bleeding. [3] The valves are normally installed with the first installation of a system, then remain in place for the life of the system. They are generally reliable and require no maintenance. If they do eventually fail, they are replaced rather than ...

3. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   A heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or other dwelling. Typically, these systems are a crucial part of an HVAC (Heating, Ventilation, and Air Conditioning) system.

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   A steam heating system takes advantage of the high latent heat which is given off when steam condenses to liquid water. In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water.

   For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...

6. Building automation - Wikipedia

   en.wikipedia.org/wiki/Building_automation

   Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building ...

7. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   In Cyprus and Israel 90 percent of homes have solar water heating systems. [3] The most basic solar thermal models are the direct-gain type, in which the potable water is directly sent into the collector. Many such systems are said to use integrated collector storage (ICS), as direct-gain systems typically have storage integrated within the ...

8. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Threaded steel pipe is widely used in buildings to convey natural gas or propane fuel and is also a popular choice in fire sprinkler systems due to its resistance to mechanical damage and high heat (including the threaded joints). Threaded steel pipe may still be used in high-security or exposed locations because it is more resistant to ...

9. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   Waste heat from fluorescent lamps is captured in the return air of the heating system; in large buildings a substantial part of the annual heating energy is supplied by the lighting system. However, this waste heat becomes a liability when using air conditioning. Such expenses can be avoided by integrating an energy efficient lighting system ...
