2. Aquastat - Wikipedia

   en.wikipedia.org/wiki/Aquastat

   [1] [2] To prevent the boiler from firing too frequently, aquastats have a high limit temperature and a low limit. If the thermostat is calling for heat, the boiler will fire until the high limit is reached, then shut off (even if the thermostat is still calling for heat). The boiler will re-fire if the boiler water temperature drops below a ...

3. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

4. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.

5. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   All new gas storage tank water heaters with capacities smaller than 55 US gal (210 L; 46 imp gal) sold in the United States in 2015 or later shall have an energy factor of at least 60% (for 50-US-gallon units, higher for smaller units), increased from the pre-2015 minimum standard of 58% energy factor for 50-US-gallon gas units. Electric ...

6. Boiler (water heating) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(water_heating)

   The boiler heats water to a temperature controlled by a thermostat. The water then flows (either by natural circulation or by a pump) to radiators in the rooms which are to be heated. Water also flows through a coil in the hot water tank to heat a separate mass of water for bathing, etc.

7. Aquastat (disambiguation) - Wikipedia

   en.wikipedia.org/wiki/Aquastat_(disambiguation)

   Aquastat is a device used in hydronic heating systems. Aquastat may refer to: Aquastat, a database of global water usage maintained by the United Nations Food and ...

8. Glossary of boiler terms - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_boiler_terms

   A generic term for water-tube boilers of the Yarrow pattern. In Royal Navy practice, a reference to the specific Admiralty example of this. [4] [5] Throatplate a plate forming the lower front of the outer firebox of a locomotive boiler, below the barrel. Top-feed in locomotive boilers, a feed water check valve placed on the top of the boiler ...

9. Radiator (heating) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(heating)

   A hot-water radiator consists of a sealed hollow metal container filled with hot water from a boiler or other heating device by gravity feed, a pump, or natural convection. As it gives out heat, the hot water cools and sinks to the bottom of the radiator and is forced out of a pipe at the other end.
