  2. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Hydronic radiant floor heating systems use a boiler or district heating to heat water and a pump to circulate the hot water in plastic pipes installed in a concrete slab. The pipes, embedded in the floor, carry heated water that conducts warmth to the surface of the floor, where it broadcasts heat energy to the room above.

  3. Centrifugal pump selection and characteristics - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump_selection...

    Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics. Performance tests are done on the pumps to verify the claims made by the pump maker.

  4. Centrifugal pump - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump

    Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  7. Heat pump - Wikipedia

    en.wikipedia.org/wiki/Heat_pump

    In general, heat pumps work most efficiently (that is, the heat output produced for a given energy input) when the difference between the heat source and the heat sink is small. When using a heat pump for space or water heating, therefore, the heat pump will be most efficient in mild conditions, and decline in efficiency on very cold days.

  8. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    Heat pumps: They can be used for heating and cooling, transferring heat using refrigerant and electricity, making them more efficient than other heating systems. [7] Heat pumps are most often used in places where the temperature stays around 40 degrees. When operating below 40° (F) heating pumps lose some of their efficiency.

  9. District heating - Wikipedia

    en.wikipedia.org/wiki/District_heating

    The Spittelau incineration plant is one of several plants that provide district heating in Vienna, Austria. Animated image showing how district heating works. District heating (also known as heat networks) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water ...
