When you are in contact with a substance that has a higher temperature than yourself.
Or when there is more infrared energy shining on you than normally.
Radiant energy (light) - the heat you feel is "infra red" radiation. Your eyes can not see this wavelength of light but there are sensors (thermal sensors) in your skin that can feel it.
Through heat, you can feel thermal energy, which is the energy that comes from the movement of particles within an object. When an object heats up, its particles move faster and this energy transfer can be felt as warmth or heat.
The heat energy you feel from a fireplace is primarily radiant heat. This heat is given off by the fire and warms objects and people in close proximity. The amount of heat felt will depend on the distance from the fireplace and the size of the fire.
You can feel the heat from the sun because the sun emits energy in the form of heat and light, which travels through space and reaches the Earth. When this energy reaches your skin, it is absorbed and converted into heat, making you feel warm.
When sunlight hits your skin, it transfers energy to the molecules in your skin, causing them to move faster and generating heat. This heat is what makes you feel warm when you're out in the sunshine.

Thermal energy doesn't actually make heat. We just feel it as heat.
That is heat energy.

A lot.
The energy you feel as heat from an electric burner is carried by electromagnetic waves called infrared rays. Particles of light energy is called photon.

-- There is no such thing as "coldness". There is heat energy. Where there is heat energy, you absorb some of it, and you feel warm. Where there is little heat energy, you lose some of the heat energy you already have, and you feel cold. -- At low altitude or on the ground, you are surrounded by the ground, by dense air, and possibly by bodies of water. All of these absorb and store heat energy efficiently from solar radiation. -- At high altitude, there is no ground nearby holding heat energy, and no bodies of water. Also, the air is less dense, and less able to hold heat energy.
Heat and light are related because they both involve the transfer of energy. When an object absorbs light, it can convert that light energy into heat energy. This is why objects can feel warm when exposed to light, as the light energy is being converted into heat energy.
The heat transfer you feel from a bonfire is primarily radiant heat transfer. This is when heat energy is transferred through electromagnetic waves from the hot flames to your body, causing you to feel warm.
