A portable heater primarily uses convection to transfer heat into a room. Air is heated inside the heater, rises, and then circulates throughout the space. Some heaters also emit radiation, where infrared waves directly heat objects in the room, but convection is the main mechanism.
The three types of energy transfers are: Conduction, the transfer by energy moving through a solid; Convection, the transfer of energy in a gas or a liquid; and Radiation, the transfer of energy through space. Conduction is how a stove warms the contents of a pan. As the pan heats up, the material inside in contact with the pan gets warm. Convection is what happens when a heater warms the air around it, causing it to rise, which creates lower pressure near the heat source, causing cooler air to flow in. Convection is a result of the differences in density resulting from differences in temperature. Convection does not work in a zero gravity environment. Radiation is how the Sun warms the Earth. Energy travels through empty space until it strikes the Earth, causing it to warm.
1. From the sun to the earth, radiation 2. Heating lamp to you, radiation 3. You touching a hot stove, conduction 4. Heater blowing hot air, convection 5. Why the air heats up during the morning radiation from the ground, which is heated by radiation from the sun. That's all I could think of on the top of my head.
Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
The three ways of transferring heat are conduction, convection, and radiation. An example of conduction is when a metal spoon placed in a hot cup of coffee becomes warm. Convection is demonstrated when hot air rises from a heater and circulates around a room. Radiation occurs when the warmth of the sun is felt on the skin.
Conduction occurs through direct contact between objects like the floor and your feet. Convection happens when warm air rises and creates air currents like in a room with a heater. Radiation occurs when heat moves in waves through space, like sunlight coming through a window.
The first: conduction from the solid heating coil
All three methods of heat transfer occur: conduction, convection, radiation. However, heaters are often designed to transfer lots of heat via radiation.

it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.

Either Convection(hot air rises - the same way you feel the heat when you hold your hand a few inches above an electric iron/heater or even a frying pan that's hot) or Radiation(the way you feel warm or hot under sunlight) or Both i.e. radiation+convection.
An infrared heater uses electromagnetic radiation to heat objects directly, while a convection gas heater warms the air in a room through the circulation of heated air.
yes it is radiation
