Common applications of coolant pumps are: Coolant pump or water pump, found in most modern internal combustion engine applications such as most fossil fuel powered vehicles; Coolant pumps, found in pressurized water reactors, a type of light water reactor used in the majority of Western world nuclear power plants
Gas water heaters are generally less energy-efficient than electric water heaters, but the cost of electricity may make gas a better choice. It really just depends on how you use your heating system.
Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine, bypassing the radiator. Directing water to circulate only through the engine allows the engine to reach optimum operating temperature as quickly as possible whilst avoiding localized "hot spots."
Flashing incandescent Christmas lights take advantage of this effect. Some flasher bulbs interrupt power when heated, while other twinkle/sparkle mini-bulbs momentarily shunt current around the filament. Thermal switches are part of the normal operation of older fluorescent light fixtures, where they are the major part of the starter module.
Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power ...

The oil pressure idiot light lights when engine oil pressure drops below a predetermined level. The light normally appears when the vehicle ignition is turned on, but the engine is not running, as it detects no oil pressure due to the oil pump not operating (the oil pump is powered off the crankshaft, so only operates when the engine is running ...
