Convector

Definition

A convector is a heat exchange device that uses the heat in steam, hot water, or an electric resistance element to warm the air in a room; often inaccurately called a radiator.

Purpose

The purpose of a convector is to provide heating by transferring heat from a hot medium (such as steam or hot water) to the air, effectively warming a room.

Examples of Use

• Convectors in residential heating systems use hot water to warm the air in living spaces.
• Office buildings use steam convectors to maintain comfortable temperatures during winter.
• Electric convectors are used in spaces where hot water or steam heating is not feasible, providing a flexible heating solution.

Related Terms

• Radiator: A heat exchanger that transfers heat from hot water or steam to the air, typically through a combination of radiation and convection.
• Heat Exchanger: A device that transfers heat between two or more fluids.
• Fan Coil Unit: A type of convector that uses a fan to move air over a coil heated by hot water or steam.

Notes

Convectors rely primarily on convection to transfer heat, which involves the circulation of air around the heated element, differing from radiators that also use radiant heat.
