Heaters (band)
Heaters is an American alternative rock band, formed in 2013 in Grand Rapids, Michigan. The band is currently composed of singer-bassist Nolan Krebs, drummer Joshua Korf, guitarist Ryan Hagan and singer-guitarist Ben Taber. The band's original co-frontman and guitarist Andrew Tamlyn left the band in March 2017 to focus on his new band Fyrrh. (fkn love these guys) History The band was originally formed as Plantains in 2013 as a four piece band including Alex Falardeau. High School friends Andrew Tamlyn (who had previously released material under the names Amish Bread and Yoke) and Nolan Krebs (who had been a member of Drone Wolves) moved to Grand Rapids from Midland, Michigan. The duo bonded over traditional surf music and "messed around with music a little bit" before parting ways to go to college. They moved to Grand Rapids with the purpose of pursuing a musical project together due to the area's music scene They enlisted Ann Arbor native Joshua Korf on drums, who was their new ...

Space Heater
A space heater is a device used to heat a single, small to medium sized area. Operation Electric space heaters fall into four main categories: fan heaters, ceramic, infrared, and oil-filled. * Fan heaters are the cheapest, but are often the least efficient and versatile. Nonetheless, they can be useful for heating small spaces, such as a small room or office cubicle. * Ceramic heaters push air across a piece of heated ceramic material. They can adequately heat a typical bedroom. * Infrared heaters provide more heat than ceramic models, and are also smaller and quieter. They do not oscillate like ceramic heaters, but consist of a heating chamber deep within the unit that prevent accidental fires, and allows for greater accumulation of heat before it is emitted by the unit. By the mid-2010s, many were outfitted with touch-screen controls and energy-saving settings, and were styled in such a way to complement the user's furniture. They grew in popularity in the 2010s. * Oi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heating Element
A heating element converts electrical energy into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. Unlike the Peltier effect, this process is independent of the direction of current. Heating elements types Metal Resistance wire: Metallic resistance heating elements may be wire or ribbon, straight or coiled. They are used in common heating devices like toasters and hair dryers, furnaces for industrial heating, floor heating, roof heating, pathway heating to melt snow, dryers, etc. The most common classes of materials used include: * Nichrome: Most resistance wire heating elements usually use nichrome 80/20 (80% Nickel, 20% Chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath this layer will not oxidize, preventing the wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heater
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh ai ...

Cathode Heater
In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission. This is in contrast to a cold cathode, which does not have a heating element. The heating element is usually an electrical filament heated by a separate electric current passing through it. Hot cathodes typically achieve much higher power density than cold cathodes, emitting significantly more electrons from the same surface area. Cold cathodes rely on field electron emission or secondary electron emission from positive ion bombardment, and do not require heating. There are two types of hot cathode. In a ''directly heated cathode'', the filament is the cathode and emits the electrons. In an ''indirectly heated cathode'', the filament or ''heater'' heats a separate metal cathode electrode which emits the electrons. From the 1920s to the 1960s, a wide variety of electronic devices used hot-cathode vacuum tubes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Heater
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil, it is electrically heated and does not involve burning any oil fuel; the oil is used as a heat reservoir (buffer), not as a fuel. Function Oil heaters consist of metal columns with cavities inside, where heat transfer oil flows freely around the heater. A heating element at the base of the heater heats up the oil, which flows around the cavities of the heater by convection. The oil has a relatively high specific heat capacity and high boiling point. The high specific heat capacity allows the oil to effectively transfer thermal energy from the heating element, while the oil's high boiling point allows it to remain in the liquid phase for the purpose of heating, so that the heater does not have to be a high pressure vessel. The heating element heats the oil, which transfers heat to the metal wall throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indirectly Heated Cathode
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the anode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Heater
A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane or butane. Indoor household gas heaters can be broadly categorized in one of two ways: ''flued'' or ''non-flued,'' or ''vented'' and ''unvented''. History The first gas heater made use of the same principles of the Bunsen burner invented in the previous year. It was first commercialized by the English company ''Pettit and Smith'' in 1856. The flame heats the air locally. This heated air then spreads by convection, thus heating the whole room. Today the same principle applies with outdoor patio heaters or "mushroom heaters" which act as giant Bunsen burners. Beginning in 1881, the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, a British engineer. Later, fire clay replaced the asbestos because it is easier to mould. Modern gas heaters still work this way although using other refractory material. M ...

Radiator (heating)
Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another for the purpose of space heating. Denison Olmsted of New Haven, Connecticut, appears to have been the earliest person to use the term 'radiator' to mean a heating appliance in an 1834 patent for a stove with a heat exchanger which then radiated heat. In the patent he wrote that his invention was ''a peculiar kind of apparatus, which I call a radiator''. The heating radiator was invented by Franz San Galli in 1855, a Kingdom of Prussia-born Russian businessman living in St. Petersburg. In the late 1800s, companies, such as the American Radiator Company, promoted cast iron radiators over previous fabricated steel designs in order to lower costs and expand the market. Radiation vs. convection In practice, the term ''radiator'' refers to any of a number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), ...

Aquarium Heater
An aquarium heater is a device used in the fishkeeping hobby to warm the temperature of water in aquariums. Most tropical Freshwater aquarium, freshwater and marine aquariums are maintained at temperatures that range from 22 to 30 °C (71-86 °F).Sands D (1994) ''A fishkeepers guide to Central American cichlids.'' Tetra Press. Belgium pg 59-60. The types include glass immersion heaters and undergravel heating. There are also heating mats that may be placed under the aquarium. Glass immersion heaters Most commonly, aquarium heaters are immersion style heaters, these heaters consist of a glass tube containing a heating element wound around a ceramic or glass insert. Some glass immersion heaters also contain sand, and most, but not all, are fully submersible. The glass tube also contains an adjustable thermostat which turns the heating element on to maintain the required temperature. This thermostat is often a bimetallic strip; because the strip contains two metals, the meta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Furnace (house Heating)
A furnace (American English), referred to as a heater or boiler in British English, is an appliance used to generate heat for all or part of a building. Furnaces are mostly used as a major component of a central heating system. Furnaces are permanently installed to provide heat to an interior space through intermediary fluid movement, which may be air, steam, or hot water. Heating appliances that use steam or hot water as the fluid are normally referred to as a residential steam boilers or residential hot water boilers. The most common fuel source for modern furnaces in North America and much of Europe is natural gas; other common fuel sources include LPG (liquefied petroleum gas), fuel oil, wood and in rare cases coal. In some areas electrical resistance heating is used, especially where the cost of electricity is low or the primary purpose is for air conditioning. Modern high-efficiency furnaces can be up to 98% efficient and operate without a chimney, with a typical gas fur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...
