Water heating - WikipediaWater 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.Solar water heating - WikipediaSolar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector.A variety of configurations is available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications.Water heating - Simple English Wikipedia, the free Water heating is a thermodynamic process using an energy source to heat water above its initial temperature.Typical domestic uses of hot water are for cooking, cleaning and bathing, and space heating. In industry both hot water and water heated to steam have many uses.. The most common energy sources for heating water are fossil fuels: natural gas, liquefied petroleum gas, oil or sometimes

Storage water heater - WikipediaA storage water heater, or a hot water system (HWS), is a domestic water heating appliance that uses a hot water storage tank to maximize heating capacity and provide instantaneous delivery of hot water. Conventional storage water heaters use a variety of fuels, including natural gas, propane, fuel oil, and electricity.Less conventional water heating technologies, such as heat pump water

Tankless water heating - WikipediaOperation. The heater is normally turned off, but is equipped with flow sensors which activate it when water travels through them. A negative feedback loop is used to bring water to the target temperature. The water circulates through a copper heat exchanger and is warmed by gas or electrical heating. [citation needed] Since there is no finite tank of hot water that can be depleted, the heater

Properties of water - WikipediaWater has a very high specific heat capacity of 4.1814 J/(g·K) at 25 °C – the second highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2257 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its molecules. These two unusual properties allow water to moderate Earth&39;s Air source heat pumps - WikipediaThe indoor air or heating water is pumped across the heat exchanger by an electric pump or fan. The cool liquid refrigerant then re-enter the outdoor heat exchanger coils to begin a new cycle. Most heat pumps can also operate in a cooling mode where the cold refrigerant is moved through the indoor coils to cool the room air.Electric heating - WikipediaElectric heating is a process in which electrical energy is converted 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 Heating, ventilation, and air conditioning - WikipediaHeating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. 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&39;s abbreviation, as
