Heat goes up right? "Heat goes up and cold goes down" is a common belief about temperature. But it's false.
All you need to do is stand in the sun to understand.
While it is incorrect to say "heat goes up", it is correct to say "hot air rises", which clarifies that the concept of heat is a broader concept which does not involve just the movement of air.
Radiana cools a ceiling by passing cold water through the pipes which absorb the heat radiated from the rest of the room. Heat always travels to colder areas. Therefore areas that are ‘colder’ will always attract heat rays to them. The hot ‘rays’ travel from the radiant heat element until they reach a surface, such as a wall, floor or piece of furniture. There are no hot or cold spots in an environment heated or cooled from the ceiling because radiation expands equally in all directions.
This is recognised by certification by the International WELL Building Institute. The Well v2 standard only gives credits to radiant cooling. Radiana can give you those credits.
