Radiant heat is typically measured on the non-fire side at a distance of 1.5 to 2 meters. Protecting people from radiant heat is vital because exposed individuals quickly feel unbearable pain, followed by second-degree burns, making safe egress impossible. When radiant heat is absorbed by a combustible material, the object catches fire when the material’s ignition temperature is reached. When these waves hit a combustible material or a person, the radiant energy is absorbed and converted into heat. Fire emits electromagnetic radiation that travels in invisible waves through space. In small doses, radiant heat can be warm and welcoming, but the amount of radiant heat generated by an uncontrolled fire can be a serious threat to life safety and property. When you warm yourself in front of a fireplace, you experience radiant heat firsthand. Where there’s fire, there’s an invisible deadly threat commonly referred to as radiant heat. Not all fire rated glass prevents the transmission of radiant heat. Fire emits electromagnetic radiation that can injure or kill passersby or result in spontaneous combustion of materials. Let us know if you would like to talk through the specific needs of your space and a solution that might work best.Radiant heat transmission is deadly. Does it make sense to run your heating system all day or would you benefit from a system that allows variable set points while providing optimal comfort when required? Do you want a system that works in conjunction with renewable energy sources, such as solar or wind? Do you need a system that reacts quickly due to internal energy loads from people gathering in a space? Ultimately, the decision comes down to your heating needs. This also helps prevent condensation buildup on the glass structure. It also helps reduce energy loss from the large windows, by as much as 35 percent as they create a curtain of air between the interior space and windows. In this system, Jaga perimeter convectors provide immediate heat to help the room get up to temperature more quickly. In practice, the Chihuly Glass Museum in Seattle uses a radiant floor system, but it can take several hours to reach the desired temperature. Many of our convectors provide supplemental heating around the perimeter of a room or space that uses a radiant system as its primary heat source. Both types of heat can be coupled together to create an effective, low-energy heating solution. Using a radiant or convection based system isn’t an either/or decision. ![]() When coupled with our supplemental Dynamic Boost Hybrid technology (low-voltage fans), the convection process becomes even faster, creating more heat transfer-with lower energy consumption.Įxamples of convection heating systems include convectors, radiators (misnomer) or fan coil systems. When this natural process of heat transfer is assisted by a fan (also known as forced convection), the convection process speeds up the warming process. ![]() ![]() This cool air warms and circulates upward, with the process continuing until the space reaches the desired temperature. Heat from the convector rises, displacing cooler air and pushing it downward. For example, if a cloud front comes through on sunny day, the convector can provide quick, supplemental heat. This allows variable set points and quick responsiveness when indoor and outdoor conditions change. Warming the air is easy and fast, which reduces the reaction time for convective systems. Inside a convector, hot water circulates through the tubes within the unit, which has small fins that increase surface contact with the surrounding air. Heat is generated within a particular source, such as a convector. When it comes to heating spaces, a convection heater uses natural air flow to transfer heat throughout a room. This is a great example of convection heat. That’s because the heat of the coffee is primarily lost to the surrounding air. What happens when you pour yourself a cup of hot coffee and get pulled away to do something else before you can drink it? It gets cold. When radiation is used as a primary heat source, it might take longer for the objects in the room to room to reach its desired temperature and for optimal thermal comfort to be achieved.Įxamples of radiant systems include panel radiators, infrared heat or hydronic radiant floors. Once those objects reach the set temperature, they also emit heat. With radiant heat, objects or people directly within the path of the heat source are first to receive heat. The sun is another great example of radiant heat. ![]() Heat radiates outward from a source in a single direction-it’s why when you sit next to the fireplace, your face gets warm but your back might feel cold. Maybe you’ve sat by a fireplace on a cool evening already this fall fireplaces are a great example of radiant heating. What’s the difference between these two popular forms of heating systems?
