THE BEST SOURCE OF HEATING

Radiant heating is the transfer of heat energy using energy waves. Heat energy in the form of radiation will always travel from a hot surfact to a cooler surface.

Consider the Sun, the Earth’s only source of heat, which is a 150 million kilometers away.

The Sun warms the Earth from a great distance purely using radiant energy.

Even before the air is warm, heat from the sun can be felt.
