  2. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Tankless gas electronic ignition water heaters. Gas water heaters have an exhaust vent or one to two exhaust pipes on the top, and still require electric power for electronics, sensing and ignition. A three-phase, 21 kW, 400-volt tankless water heater in Europe, with new European color coding for three-phase power.

  3. Circulator pump - Wikipedia

    en.wikipedia.org/wiki/Circulator_pump

    This avoids one of the principal challenges faced by the larger, two-part pumps: maintaining a water-tight seal at the point where the pump drive shaft enters the pump body. Small- to medium-sized circulator pumps are usually supported entirely by the pipe flanges that join them to the rest of the hydronic plumbing. Large pumps are usually pad ...

    Under the pre-2015 standard, a 75 US gal (280 L; 62 imp gal) gas storage water heater with a nominal input of 22 kW (75,000 BTU/h) or less was able to have an energy factor as low as 53%, while under the 2015 standard, the minimum energy factor for a 75-US-gallon gas storage tank water heater is now 74%, which can only be achieved by using ...

  5. Solenoid valve - Wikipedia

    en.wikipedia.org/wiki/Solenoid_valve

    A 3-way valve has 3 ports; it connects one port to either of the two other ports (typically a supply port and an exhaust port). The solenoid valve (small black box at the top of the photo) with input air line (small green tube) used to actuate a larger rack and pinion actuator (gray box) which controls the water pipe valve

  6. Booster pump - Wikipedia

    en.wikipedia.org/wiki/Booster_pump

    Booster pumps for household water pressure are usually simple electrically driven centrifugal pumps with a non-return valve. They may be constant speed pumps which switch on when pressure drops below the low pressure set-point and switch off when pressure reaches the high set-point, or variable speed pumps which are controlled to maintain a ...

  7. Pump - Wikipedia

    en.wikipedia.org/wiki/Pump

    In some impulse pumps the gas trapped in the liquid (usually water), is released and accumulated somewhere in the pump, creating a pressure that can push part of the liquid upwards. Conventional impulse pumps include: Hydraulic ram pumps – kinetic energy of a low-head water supply is stored temporarily in an air-bubble hydraulic accumulator ...

  8. Submersible pump - Wikipedia

    en.wikipedia.org/wiki/Submersible_pump

    Submersible pump cables are electrical conductors designed for use in wet ground or under water, with types specialized for pump environmental conditions. [5] [6] [7] A submersible pump cable is a specialized product to be used for a submersible pump in a deep well, or in similarly harsh conditions.

  9. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    A means had to be provided, of course, to put the initial charge of water into the boiler (before steam power was available to operate the steam-powered feedwater pump). The pump was often a positive displacement pump that had steam valves and cylinders at one end and feedwater cylinders at the other end; no crankshaft was required.
