Boiler (water Heating)
The term boiler may refer to an appliance for heating water. Applications include water heating and central heating. Operation The boiler heats water to a temperature controlled by a thermostat. The water then flows (either by natural circulation or by a pump) to radiators in the rooms which are to be heated. Water also flows through a coil in the hot water tank to heat a separate mass of water for bathing, etc. Condensing boiler Back boiler A back boiler is a device which is fitted to a residential heating stove or open fireplace to enable it to provide both room heat and domestic hot water or central heating.

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 potable or non-potabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Heating
A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators. Primary energy sources may be fuels like coal or wood, oil, kerosene, natural gas, or electricity. Compared with systems such as fireplaces and wood stoves, a central heating plant offers improved uniformity of temperature control over a building, usually including automatic control of the furnace. Large homes or buildings may be divided into individually controllable zones with their own temperature controls. Automatic fuel (and sometimes ash ...

Electric Water Boiler
An electric water boiler, also called a thermo pot, is a consumer electronics small appliance used for boiling water and maintaining it at a constant temperature in an enclosed reservoir. It is typically used to provide an immediate source of hot water for making tea, hot chocolate, coffee, instant noodles, or baby formula, or for any other household use where clean hot water is required. They are a common component of Japanese kitchens and the kitchens of many East Asian countries but are found in varying use globally. Smaller units are portable. Some thermo pots are designed with a feature that can purify water. Components An electric water boiler consists of a water reservoir with a heating element at the bottom. Some models offer multiple temperature settings. Other models are part of larger water systems that boil water and provide hot, cold, and lukewarm water. Water may be dispensed in various ways, e.g. by pouring, an electric pump or by pressing a large button that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat-only Boiler Station
A heating plant, also called a physical plant, or steam plant, generates thermal energy in the form of steam for use in district heating applications. Unlike combined heat and power installations which produce thermal energy as a by-product of electricity generation, heating plants are dedicated to generating heat for use in various processes. Heating plants are commonly used at hospital or university campuses, military bases, office tower complexes, and public housing complexes. The plant will generate steam which is distributed to each building where it is used to make domestic hot water for human consumption, heating hot water in the case of hydronic heating systems, air conditioning through the use of absorption refrigeration units, air heating in HVAC units, humidification, industrial laundry systems, or sterilization at hospitals. The steam may be sold to each customer and billed through the use of a steam flow meter. They feature boilers, either water tube or fire tu ...

Multi-fuel Stove
A multi-fuel stove is similar to a wood-burning stove in appearance and design. Multifuel refers to the capability of the stove to burn wood and also coal, wood pellets, or peat. Stoves that have a grate for the fire to burn on and a removable ash pan are generally considered multi-fuel stoves. If the fire simply burns on a bed of ash, it is a wood-only fuelled appliance, and cannot be used for coal or peat. Home use Multi-fuel stoves have been common in the northern United Kingdom, Ireland, and continental Europe since the 19th century. They are made either for cooking, heating, or both. They may double as a boiler, heating a tank of water for household use. With a boiler, the stove can also be connected to a radiator system to increase space heating in the home. As people turn to alternative ways of heating such stoves have become increasingly popular. In Scotland and Ireland in particular, coal and peat have historically been common solid fuel for stoves. Peat cutters use a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heating, Ventilation, And Air Conditioning
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, us ...

Residential Heating Appliances
A residential area is a land used in which housing predominates, as opposed to industrial and commercial areas. Housing may vary significantly between, and through, residential areas. These include single-family housing, multi-family residential, or mobile homes. Zoning for residential use may permit some services or work opportunities or may totally exclude business and industry. It may permit high density land use or only permit low density uses. Residential zoning usually includes a smaller FAR (floor area ratio) than business, commercial or industrial/manufacturing zoning. The area may be large or small. Overview In certain residential areas, especially rural, large tracts of land may have no services whatever, such that residents seeking services must use a motor vehicle or other transportation, so the need for transportation has resulted in land development following existing or planned transport infrastructure such as rail and road. Development patterns may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
