HVAC • Heaters

Air heaters are devices that are designed to heat an enclosed area. Types of heaters include convective heaters, and radiative heaters.

A heater is a device that emits heat or causes another object or substance to reach a higher temperature. Common types include central, electric, gas, oil, space, and water heaters. A central heater is key to a central heating system, which can warm the interior of an entire structure rather than individual rooms. Space heaters, by contrast, are small, portable units used to heat small spaces.Electric heaters include all appliances that convert electric energy into heat; this is the operating principle behind many space heaters, convection heaters, storage heaters, and water heaters. Gas heaters burn natural gas or liquefied petroleum, and include patio heaters and indoor household gas heaters. Oil heaters are used to warm small rooms, and are safer than electric fan heaters and gas heaters due to lower surface temperatures and their lack of emissions. Lastly, water heaters use a thermodynamic process to heat water for cooking, cleaning, bathing, and space heating.Leading manufacturers: Holmes, Honeywell, Espar, Lasko, DeLonghi,, Mr. Heater, Coleman and The Heater Shop.
