2. Automatic bleeding valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_bleeding_valve

   Brass-bodied float valve. An automatic bleeding valve or air release valve (ARV) is a plumbing valve used to automatically release trapped air from a heating system. Air, or other gas, may collect within plumbing. For water delivery systems to taps and basins, particularly with good main supply pressure, this air is usually flushed through with ...

3. Edwin Ruud - Wikipedia

   en.wikipedia.org/wiki/Edwin_Ruud

   A Ruud Type F Size no. 3 instantaneous and automatic water heater from 1906. The Thermal Valve Model, Type F, of the Ruud Instantaneous Automatic Water Heater is a design that allows the user to instantaneously heat water for on demand applications while not heating, thus saving fuel, when not in use.

4. Automatic balancing valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_balancing_valve

   Traditional control valves make it inevitable. As we size a control valve, the K v calculated almost certainly will not match the K v of the nearest appropriate valve. For example, a K v calculation of 4.5 m 3 /h would most likely lead to the selection of a valve with a K v = 6.3 m 3 /h. This means the valve is capable of delivering 40% more ...

5. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   A water heater is still sometimes called a geyser in the UK and South Africa. Maughn's invention influenced the work of a Norwegian mechanical engineer named Edwin Ruud. The first automatic, storage tank-type gas water heater was invented around 1889 by Ruud after he immigrated to Pittsburgh, Pennsylvania (US). The Ruud Manufacturing Company ...

6. Heat trap - Wikipedia

   en.wikipedia.org/wiki/Heat_trap

   Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water to flow out of the tank. [1] [2] Newer water heaters have built-in heat traps.

7. 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 ...
