Heating techniques refer to various methods used to increase the temperature of a space or object. Common techniques include convection, where warm air circulates, and radiation, which involves heat transfer through electromagnetic waves. Conduction is another method, where heat moves through direct contact between materials. In residential settings, heating systems often utilize furnaces or boilers to provide warmth. Heat pumps are also popular, as they transfer heat from outside to inside. Each technique has its advantages and is chosen based on factors like efficiency, cost, and the specific heating needs of a space.
