Q
What is the difference between radiant, convection, and conduction systems?
How can you tell the difference between them?
A
Radiant heating: Radiant heat works by directly heating up the surfaces or objects in a room. Ex: floor heating, sidewalk heating
Convection heating: Convection heating transfers heat by moving it from a heat exchanger to the air around it. Ex: Hydronic radiators, forced air convection,
Conduction heating systems transfer heat from a hot surface directly to a cooler surface. Ex: stovetop heats a pan
