2. Circulator pump - Wikipedia

   en.wikipedia.org/wiki/Circulator_pump

   A circulator pump for home use. A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit with small elevation changes. They are commonly found circulating water in a hydronic heating or cooling system.

3. High efficiency glandless circulating pump - Wikipedia

   en.wikipedia.org/wiki/High_efficiency_glandless...

   The primary design factors of a high efficiency glandless circulating pump include an electronically commutated synchronous motor, a permanent magnet rotor, and canned rotor technology. An electronically commutated synchronous motor is used to convert the energy current from a DC energy source into an AC current which is supplied to the drive ...

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   A supply of fuel, electric power or district heating supply lines; A boiler (or a heat exchanger for district heating) which heats water in the system; Pump to circulate the water; Radiators through which the heated water passes in order to release heat into rooms. The circulating water systems use a closed loop; the same water is heated and ...

5. Zone valve - Wikipedia

   en.wikipedia.org/wiki/Zone_valve

   Higher initial installation cost. Circulator pumps cost more than zone valves; Higher power consumption. Operating circulators draw more power any time the zone is actively heating. Zone valves, by comparison, draw little power at any time and many designs only draw power while in transition from open to close or vice versa.

6. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   The blower motors on these single-stage furnaces consume more energy overall because, regardless of the heating requirements of the space, the fan and blower motors operate at a fixed-speed. Due to its One-Speed operation, a single-stage furnace is also called a single-speed furnace.

7. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...
