Electric Shower
An electric shower or electric shower head are self-heating shower heads that use an immersion heater which is turned on with the flow of water. A group of separate electric heating elements can be switched to offer different heating levels. They are specialized point-of-use tankless water heaters and are widely used in some countries. Invented in Brazil by Francisco Canhos in the 1930s due to a lack of central gas distribution and used frequently since the 1940s, the electric shower is a home appliance often seen in South and Central American countries due to the higher costs of gas distribution, combined with households that in most cases do not support conventional water heaters. Earlier models were made of chromed copper or brass, which were expensive, but since 1970, units made of injected plastics are popular due to low prices similar to that of a hair dryer. Electric showers have a simple electric system, working like a coffee maker, but with a larger water flow. A flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shower Head
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers are set up to have adjustable temperature, spray pressure and showerhead nozzle angle. The simplest showers have a swivelling nozzle aimed downward, while more complex showers have a showerhead connected to a hose that has a mounting bracket; this allows the showerer to hold the showerhead by hand to spray the water onto different parts of their body. A showerhead can be installed in a small shower stall, or bathtub, with a plastic shower curtain or door. Showering is common due to the efficiency of using it compared with using a bathtub. Its use in hygiene is, therefore, common practice. History Waterfalls have historically been used as primitive forms of showers. The falling water rinsed the bathers completely clean and was more efficient than bathing in a traditional basin, which required manual transport of both fresh and wast ...

Immersion Heater
Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. Alternatively, a heat pump can achieve around 150% – 600% efficiency for heating, or COP 1.5 - 6.0 Coefficient of performance, because it uses electric power only for transferring existing thermal energy. The heat pump uses an electric motor to drive a reversed refrigeration cycle, that draws heat energy from an ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tankless Water Heater
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 ...

Francisco Canhos
Francisco is the Spanish and Portuguese form of the masculine given name ''Franciscus''. Meaning of the name Francisco In Spanish, people with the name Francisco are sometimes nicknamed "Paco". San Francisco de Asís was known as ''Pater Communitatis'' (father of the community) when he founded the Franciscan order, and "Paco" is a short form of ''Pater Communitatis''. In areas of Spain where Basque is spoken, "Patxi" is the most common nickname; in the Catalan areas, "Cesc" (short for Francesc) is often used. In Spanish Latin America and in the Philippines, people with the name Francisco are frequently called "Pancho". " Kiko"and "Cisco" is also used as a nickname, and "Chicho" is another possibility. In Portuguese, people named Francisco are commonly nicknamed " Chico" (''shíco''). People with the given name * Pope Francis (1936-2025) is rendered in the Spanish, Portuguese and Filipino languages as Papa Francisco * Francisco Acebal (1866–1933), Spanish writer and author ...

Coffee Maker
A coffeemaker, coffee maker or coffee machine is a cooking appliance used to brew coffee. While there are many different types of coffeemakers, the two most common brewing principles use gravity or pressure to move hot water through coffee grounds. In the most common devices, coffee grounds are placed into a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot, a cooking pot in the kettle family. Cold water is poured into a separate chamber, which is then boiled and directed into the funnel and allowed to drip through the grounds under gravity. This is also called '' automatic drip-brew''. Coffee makers that use pressure to force water through the coffee grounds are called espresso makers, and they produce espresso coffee. Types Drip coffeemaker The first non-electric drip coffee maker, using notebook paper as the precursor to the paper coffee filter, was developed by German entrepreneur Melitta Bentz in 1908. The same year, she founded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nichrome
Nichrome (also known as NiCr, nickel-chromium or chromium-nickel) is a family of alloys of nickel and chromium (and occasionally iron) commonly used as resistance wire, heating elements in devices like toasters, electrical kettles and space heaters, in some dental restorations (fillings) and in a few other applications. Patented in 1906 by Albert Marsh (US patent 811,859), nichrome is the oldest documented form of resistance heating alloy. The A Grade nichrome alloy is 80% nickel and 20% chromium by mass, but there are many other combinations of metals for various applications. Properties C Grade Nichrome is consistently silvery in color, is corrosion-resistant, has a high melting point of approximately , and has an electrical resistivity of around 1.12 μΩ·m, which is around 66 times higher resistivity than copper of 16.78 nΩ·m. Some nichrome formulations have a resistivity as low as 1.0 μΩ·m or as high as 1.5 μΩ·m. Almost any conductive w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circuit Breaker
A circuit breaker is an electrical safety device designed to protect an Electrical network, electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse (electrical), fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are commonly installed in distribution boards. Apart from its safety purpose, a circuit breaker is also often used as a main switch to manually disconnect ("rack out") and connect ("rack in") electrical power to a whole electrical sub-network. Circuit breakers are made in varying current ratings, from devices that protect low-current circuits or individual household appliances, to switchgear designed to protect high voltage, high-voltage circuits feeding an entire city. Any device which pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathing
Bathing is the immersion of the body, wholly or partially, usually in water, but often in another medium such as hot air. It is most commonly practised as part of personal cleansing, and less frequently for relaxation or as a leisure activity. Cleansing the body may be solely a component of personal hygiene, but is also a spiritual part of some religious rituals. Bathing is also sometimes used medically or therapeutically, as in hydrotherapy, ice baths, or the mud bath. People bathe in water at temperatures ranging from very cold to very hot, or in appropriately heated air, according to custom or purpose. Where indoor heated water is available, people bathe more or less daily, at comfortable temperatures, in a private bathtub or shower. Public bathing, Communal bathing, such as that in hammams, sauna, banya, Victorian Turkish baths, and sentō, fulfils the same purpose, in addition to its often having a social function. Ritual religious bathing is sometimes referred to as Imm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumbing
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses piping, pipes, valves, piping and plumbing fitting, plumbing fixtures, Storage tank, tanks, and other apparatuses to convey fluids. HVAC, Heating and cooling (HVAC), Sewerage, waste removal, and Drinking water, potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, ''plumbum'', as the first effective pipes used in the Sanitation in ancient Rome, Roman era were lead pipes. In the developed world, plumbing infrastructure is critical to public health and sanitation. Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing. History Plumbing originated during ancient civilizations, as they developed public baths and needed to provide drinking water, potable water and sewerage, wastewater removal for large ...
