Infrared heating is the go-to choice for many applications, including industrial, commercial, aerospace, military, outdoor and patio, and stadiums and sports venues. One key advantage to infrared heat is the ability to provide comfort without the additional energy requirements of heating all the air. This becomes especially important in spaces that have a high air change rate per hour, like loading docks, maintenance facilities, and even stadiums.
But how important is ventilation for these systems? This webinar will help you understand ventilation requirements for infrared heaters while offering you the opportunity to earn one PDH credit.

Air in a hydronic HVAC system can be a problem, specifically when it comes to the development of corrosive iron oxide. When system components, like pump volutes or expansion tanks, made of cast iron or steel are mixed with oxygen and water, corrosive iron oxide is formed. Commonly known as "black sludge," iron oxide includes magnetite. Magnetite is a naturally occurring brownish-black or black material that is extremely fine and becomes a black, sticky mess inside hydronic systems. Magnetite can get into valves and ECM motors. It can also build up on the surfaces in a boiler or heat exchanger and act as an insulator to reduce heat transfer and system efficiency.
