Chip Heater
The chip heater is a single point, tankless, domestic hot water system popular in Australia and New Zealand from the 1880s until the 1960s. Examples of this form of domestic water heater are still in use. The chip heater consisted of a cylindrical unit with a fire box and flue, through which a water pipe was run. Water was drawn from a cold water tank and circulated through the fire box. When heated, the water was drawn off to the area where it was used, typically in a bath or shower. There was often an ash box under the fire box, which allowed air under the fire, as well as various dampers in the flue. The fire box was relatively small and fed by tinder, such as newspaper, pine cones, small twigs, or wood chips. The use of the later gave the chip heater its name. Water had to be run at a trickle in order to heat up to a desirable temperature. The rate of combustion was controlled by the flues and the ash box. With a lot of fuel and open flues the water could boil quickly, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Heating
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as ''water heaters'', ''kettles'', ''cauldrons'', ''pots'', or ''coppers''. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies with the consumption rate, becoming cooler as flow increases. Appliances that provide a continual supply of hot water are called ''water heaters'', ''hot water heaters'', ''hot water tanks'', ''boilers'', ''heat exchangers'', ''geysers'' (Southern Africa and the Arab world), or ''calorifiers''. These names depend on region, and whether they heat Drinking water, potable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metters Limited
Metters was a brand of stoves and ovens made by Metters & Company, an Australian company established in Adelaide in 1891 by Frederick Metters (1858–1937), who patented and manufactured a number of kitchen appliances notably the 'top-fire' wood stoves. His brothers Charles Henry Metters (c. 1853–1929) and John Thomas Metters (c. 1853–1924) had earlier founded Metters Bros., making stoves and ovens in Melbourne. Production and distribution of Metters equipment was expanded from Adelaide to Perth, Western Australia, in 1894 where Fred Metters formed a partnership with Henry Spring (1864–1937), and then to Sydney, New South Wales in 1902. Spring bought out his partner in 1907 and founded Metters Limited in 1908 with himself as managing director, and greatly expanded the product range and volume of manufacture in Perth, Adelaide and Sydney. The Spring years Henry Langdon Spring (c. 1863 – 21 April 1937) was born in London and emigrated to Perth, Western Australia around ...

Tankless Water Heating
Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil unless the unit is equipped with an internal buffer tank. Copper heat exchangers are preferred in these units because of their high thermal conductivity and ease of fabrication. However, copper heat exchangers are more susceptible to scale buildup than stainless steel heat exchangers. Tankless heaters may be installed throughout a household at more than one point-of-use (POU), far from or without a central water heater, or larger centralized whole house models may still be used to provide all the hot water requirements for an entire house. The main advantages of tankless water heaters are a plentiful, practically limitless continuous flow of hot water (as compared to a limited flow of continuous ...

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...

Coal Gas
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. The original coal gas was produced by the coal gasification reaction, and the burnable component consisted of a mixture of carbon monoxide and hydrogen in roughly equal quantities by volume. Thus, coal gas is highly toxicity, toxic. Other compositions contain additional Calorific Value, calorific gases such as methane, produced by the Fischer–Tropsch process, and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Prior to the development of natural gas supply and transmission—during the 1940s and 1950s in the United States and during the late 1960s and 1970s in the United Kingdom and Australia—almost all gas for fu ...

Farthing (British Coin)
The farthing (from Old English ''fēorðing'', from ''fēorða'', a fourth) was a British coin worth one quarter of a penny, or of a pound sterling. Initially minted in copper, and then in bronze, it replaced the earlier English farthing. Between 1860 and 1971, the farthing's purchasing power ranged between 12p and 0.2p in 2017 values. The farthing's reverse bore an image of Britannia until 1937, when a wren was introduced. As with all British coins, the obverse bore the image of the reigning monarch. The farthing ceased to be legal tender in the United Kingdom on 1 January 1961. History A British copper farthing succeeded the English farthing after England and Scotland were united into the Kingdom of Great Britain in 1707, although not immediately. Under Queen Anne, a small number of pattern farthings were struck, but none for circulation, as so many English farthings from previous reigns were still available. Some British copper farthings were struck in the reigns of G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Boiler
A vertical boiler is a type of fire-tube boiler, fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam-powered vehicles and other mobile machines, including early steam locomotives. Design considerations Tube arrangements Many different tube arrangements have been used. Examples include: ;Fire tubes * Vertical fire-tube boiler * Vertical boiler with horizontal fire-tubes ;Water tubes * Vertical cross-tube boiler * Field-tube boiler * Thimble tube boiler * Spiral watertube boiler Advantages The main advantages of a vertical boiler are: * Small footprint – where width and length constraints are critical, use of a vertical boiler permits design of a smaller machine. * Water-level tolerance – The water level in a horizontal boiler must be maintained above the crown (top) of the firebox at all times, or the crownplate could overheat and buckle, causing a bo ...

Social History
Social history, often called history from below, is a field of history that looks at the lived experience of the past. Historians who write social history are called social historians. Social history came to prominence in the 1960s, spreading from schools of thought in the United Kingdom and France which posited that the Great Man view of history was inaccurate because it did not adequately explain how societies changed. Instead, social historians wanted to show that change arose from within society, complicating the popular belief that powerful leaders were the source of dynamism. While social history came from the Marxist view of history ( historical materialism), the cultural turn and linguistic turn saw the number of sub-fields expand as well as the emergence of other approaches to social history, including a social liberal approach and a more ambiguous critical theory approach. In its "golden age" it was a major field in the 1960s and 1970s among young historians, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
