Radiant heating is the transfer of heat energy using energy waves. Heat energy in the form of radiation will always travel from a hot surface to a cooler surface. Consider the Sun, the Earth’s only source of heat, which is 150 million Km away. The Sun warms the Earth from a fantastic distance purely using radiant energy. Even before the air is warm, heat from the sun can be felt, such on a clear winter morning, or on top of a snowy mountain. Warmth from the sun is instantaneous – you experience this when the sun emerges from behind a cloud.

So perhaps it’s no surprise that radiant heating is the form of warmth most comfortable to humans, whether from the sun, a burning fireside or today’s energy efficient, discrete heating systems.
