Convection heat is the transfer of heat through the movement of fluids, like air or water, while radiant heat is the transfer of heat through electromagnetic waves, like from the sun or a fire.
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
Heat energy is the transfer of thermal energy between objects due to a difference in temperature, typically through conduction, convection, or radiation. Radiant energy, on the other hand, is a form of energy that travels in waves or particles, such as light or electromagnetic radiation, and does not require a medium to transfer. Heat energy is a specific type of energy related to temperature difference, whereas radiant energy is a broader category that includes various forms of energy propagation.
In a structure fire, convection is the most important method of heat transfer. Convection is the transfer of heat through the movement of fluids like air or gases. In a structure fire, hot air and gases rise, carrying heat with them and spreading the fire to other parts of the structure.
Conduction is the transfer of heat through direct contact between objects or substances, while convection is the transfer of heat through the movement of fluids or gases.
Conduction is the transfer of heat through direct contact between objects or substances, such as touching a hot pan. Convection is the transfer of heat through the movement of fluids, such as air or water, which results in the circulation of heat, like in a convection oven.

Radiant heaters heat objects nearby them such as furniture and are usually cheaper. Regular convection heaters actually heat the air temp in the room.
Radiant energy is heat transferred through electromagnetic waves, such as from the sun or a fire. Convection energy is heat transferred through the movement of fluids or gases, such as warm air rising and cool air sinking. They represent different mechanisms of heat transfer.

Some of it is, though some of it is convection.

No. Convection currents are the result of a temperature difference between one depth and another in fluid.
Conduction is the transfer of heat through direct contact between objects or substances, while convection is the transfer of heat through the movement of fluids or gases.

The formula for calculating heat transfer by convection is: Q = h * A * ΔT, where Q is the heat transfer rate, h is the convection heat transfer coefficient, A is the surface area, and ΔT is the temperature difference between the surface and the surrounding fluid.
Heat can travel through conduction, which is the transfer of heat through direct contact between particles; convection, which is the transfer of heat through the movement of fluids or gases; and radiation, which is the transfer of heat through electromagnetic waves.
Thermal curtains help reduce heat transfer through conduction and convection by providing an additional barrier between the window and the room. They do not have a significant impact on reducing radiant heat transfer.
