Water heating, the heating of water for residential, commercial or industrial use

HVAC: Heating, ventilation and air-conditioning

A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating...

A thermostat is a device for regulating the temperature of a system so that the system's temperature is maintained near a desired setpoint temperature. The thermostat does this by controlling the flow of heat energy into or out of the system. That is,...

District heating, a system for distributing heat generated in a centralized location for residential and commercial heating requirements

Geothermal heat pump, a heat pump that uses the thermal mass of the Earth to regulate indoor temperatures

Radiator, a heat exchanger designed to transfer thermal energy from one medium to another for the purpose of cooling and heating

Radiant heating, a heating system which heats a building through radiant heat rather than convection or forced-air heating

Hydronics, the use of water as the heat-transfer medium in heating and cooling systems

Storage heater, an electrical appliance which stores heat at a time when base load electricity is available at a low price

Central heating, method of providing warmth from one point to multiple rooms or apartments of a building

Fireplace, an architectural element consisting of a space designed to contain a fire for heating or cooking

Ventilation

Induction heating, the process of heating a metal object by electromagnetic induction

Solar heating, the usage of solar energy to provide process, space or water heating

Heating pad, a pad used for warming of parts of the body

Feedwater heater, a power plant component used to pre-heat water delivered to the boiler

Block heater, or headbolt heater, an electric heater that heats the engine of a car to ease starting in cold weather

Dielectric heating, the phenomenon in which radiowave or microwave electromagnetic radiation heats a dielectric material

Solar furnace a structure used to harness the sun's rays to produce very high temperatures

Radioisotope heater unit, small heaters that provide heat through radioactive decay

Cathode heater, a coil or filament used to heat the cathode in a vacuum tube or cathode ray tube

Gas heater, a heater that burns natural gas or liquefied petroleum gas

Geothermal heating a method of heating using geothermal heat

A heater is any object that emits heat or causes another body to achieve a higher temperature. In a household or domestic setting, heaters are commonly used to generate heating (ie. warmth). In electronics, the term may refer to the filament in a vacuum...

Fan heater, a heater that works by using a fan to pass air over a heating element

Convector heater, a heater which operates by air convection currents circulating through the body of the appliance

Salamander heater, a portable forced-air or convection heater, often kerosene-fueled, used in ventilated areas for worksite comfort
