A hot water storage tank (also called a hot water tank, thermal storage tank, hot water thermal storage unit, heat storage tank, hot water cylinder, and geyser) is a water tank used for storing hot water for space heating or domestic use. Water is a convenient heat storage medium because it has a high specific heat capacity. This means ...
Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.
Where hot-water space heating boilers are installed, domestic hot water cylinders are usually heated indirectly by primary water from the boiler, or by an electric immersion heater (often as backup to the boiler). In the UK these vessels are called indirect cylinders and direct cylinders, respectively. Additionally, if these cylinders form part ...
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 water on demand. [6] The hybrid approach is designed to eliminate general shortcomings of other technologies.
Early hot water systems were used in Ancient Rome for heating the Thermæ. [13] Another early hot water system was developed in Russia for central heating of the Summer Palace (1710–1714) of Peter the Great in Saint Petersburg. Slightly later, in 1716, came the first use of water in Sweden to distribute heating in buildings.

Water jackets were used to cool the barrels of machine guns until several years after the First World War, but modern machine guns are air-cooled to conserve weight and hence increase portability. In a reciprocating piston internal combustion engine , the water jacket is a series of holes either cast or bored through the main engine block and ...
