Radiation/Convection

Radiation
Heat propagation by radiation is the emission of heat as invisible light. These rays travel through the air until they reach some material that absorbs them. As a result the receiving material heats up.
This type of heat is ideal in a room with high ceilings, in poorly insulated buildings, or if you are looking for quick, direct heat from your home. When placing furniture or any other object, keep in mind that the proximity of the stove can be extremely hot. Heat shields can be used to prevent heat radiation in certain directions.
Convection

Heat spread by convection occurs when the air around the stove is heated, expands and rises due to its own temperature. If the stove has a chamber
convection (plates on the sides with lower and upper openings) the air in said chamber heats up sooner and circulates more quickly. Convection hot air circulation distributes heat throughout the room.
The hot air is trapped under the ceiling but can be brought down using a ceiling fan. Convection takes a little longer to heat the room compared to radiation.

Convection and radiation

Most homes combine both systems. The front of the stoves radiates heat through the glass door.
Behind the stoves, there are usually convection plates that fulfill the double function of protecting the wall. Even more often the design of the sides of the product determines whether the stove can be classified as a radiation or convection stove.
