2. Thermostatic radiator valve - Wikipedia

   en.wikipedia.org/wiki/Thermostatic_radiator_valve

   A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.

3. Thermostatic mixing valve - Wikipedia

   en.wikipedia.org/wiki/Thermostatic_mixing_valve

   There are three main categories for water temperature controlling devices: Heat Source, Group Control, and Point-of-Use. Heat Source. These are used with central heating systems that use water as a medium. Tempering valves for use on hot water heat distribution systems; High flow rates suitable for use in under floor (radiant) heating applications

4. 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.

5. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection , and pressurization of the vessel to the specified ...

6. Condensing boiler - Wikipedia

   en.wikipedia.org/wiki/Condensing_boiler

   Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value ) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

7. 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.
