otsekuumutamise
Otsekuumutamise, meaning direct heating in Estonian, refers to a method of heating where the heat source is in direct contact with the object or space being heated. This contrasts with indirect heating methods, which use an intermediate medium like steam or hot water. In its simplest form, direct heating can involve flames from a fire or a heating element placed directly against a surface.
Examples of direct heating are common in everyday life. A campfire directly heats the air and objects
The advantages of direct heating often include efficiency, as there are fewer steps for heat transfer and
