Heating System
A heating system is a mechanism designed to regulate and maintain a desired temperature within a space by utilizing thermal energy. It is a fundamental component of Heating, Ventilation, and Air Conditioning (HVAC) systems, providing warmth to residential, commercial, and industrial buildings. Heating systems are classified into two main types: central heating and distributed heating. Central heating systems generate heat (electrically or by burning gas/coal) in a single location and distribute the heat through ducts pipes or radiators. Distributed heating systems involve localized heat sources, such as space heaters or electric radiators. Distributed heating systems do not rely on the use of ducts, pipes or radiators. These systems are critical to ensure indoor comfort especially in colder regions. Types and uses Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat ...

Central Heating
A central heating system provides warmth to a number of spaces within a building from one main source of heat. A central heating system has a Furnace (central heating), furnace that converts fuel or electricity to heat through processes. The heat is circulated through the building either by fans forcing heated air through Duct (flow), ducts, circulation of low-pressure steam to Radiator, radiators in each heated room, or Pump, 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 Fireplace, fireplaces and Wood-burning stove, 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 control, temperature controls. Automatic fuel (and sometimes ash) handli ...

HVAC
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 fres ...

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 ...

Radiator
A radiator is a heat exchanger used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of #Heating, heating an environment, or for cooling the fluid or coolant supplied to it, as for automotive #Engine cooling, engine cooling and Heating, ventilation, and air conditioning, HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussia, Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason and Scot Rory Gregor developed a ...

Solar Energy
Solar energy is the radiant energy from the Sun's sunlight, light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include designing a building for better daylighting (architecture), daylighting, selecting materials with favorable thermal mass or light-dispersing properties, and organizing spaces that ventilation (architecture), naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technolo ...

Heating Plant
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 t ...
