It is heat transfer by radiation.
Forced convection. Heat is transferred through the air in the room by the movement of the air from the heating vents.
An iron uses conduction to transfer heat from its heating element to the fabric being ironed. This is because direct contact is necessary for the heat to be transferred efficiently.
An oven primarily uses radiation to transfer heat to the food being cooked. This is because the heat is generated by heating elements in the oven walls, which radiate heat towards the food.
A toaster uses radiation heat transfer to heat up and toast the bread. The heating elements inside the toaster generate heat through electrical resistance, which is then transferred to the bread through radiation.
Microwaves use radiation to heat food. The microwaves penetrate the food and cause the water molecules inside to vibrate, generating heat through friction. This is a form of heat transfer known as radiation heating.
Convection.

Heat transfer in an oven is the process by which heat is transferred from the heating elements to the food being cooked. This can occur through conduction, convection, or radiation, depending on the type of oven and the cooking method being used.
An iron uses conduction as the primary method of heat transfer. Heat is transferred from the heating element inside the iron to the soleplate, which then heats up the fabric through direct contact.
An HVAC contractor is hired when there is a need for a heating repair. HVAC stands for heating, ventilation and air conditioning. This professional has been trained in heat transfer.
A curling iron transfers heat through conduction. The heat from the iron's heating elements is transferred directly to the hair when it comes into contact with the curling iron's barrel.
A hair dryer will use convection.
