38 - Heating System General Maintenance

Question 1

What is the difference between radiant, convection, and conduction systems?

How can you tell the difference between them?

Answer 1

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

Question 2

How can the different heat transfer mediums be identified? (Water, steam, and air)
