  • Radiant heat is how the sun heats the earth, at a distance of 93 million miles.
  • High temperature air rises in the building delivering the heat to the roof space rather than the occupied area of the building. “The Chimney Effect”

    2. 2. Principles in Radiant Heating <ul><li>Properties of radiant energy </li></ul><ul><li>Emitted by hot surfaces </li></ul><ul><li>Travels in straight lines </li></ul><ul><li>Passes through the air without heating it </li></ul><ul><li>Absorbed by cooler solid objects on which it falls, heating them </li></ul>
    3. 3. Understanding Radiant Heating <ul><li>Heaters which utilize infrared energy can heat objects and people directly without having to directly heat the air. </li></ul><ul><li>Warms the air near the objects and floor via convection. </li></ul><ul><li>Is reradiated to occupants and other surfaces of the space. </li></ul><ul><li>Minimizes stratification to ceiling, lowering roof losses. </li></ul><ul><li>Eliminates exfiltration caused by moving air across exterior surfaces & out through openings </li></ul>
    4. 4. High Temperature Air = High Stratification & Increased Roof Loss Moving Air Increases Surface Losses & Exfiltration Resulting In: Higher operating costs, Uneven heat distribution, Not easily zoned & Slow recovery - warm-up 60 F Air Temp 90 °F 68 °F 75 °F Warm Air Heating
    5. 5. . No or Minimal Stratification and Decreased Roof Loss No Moving Air Decreases Surface Losses & Exfiltration Resulting In: Lower Operating Costs, Comfortable Even Heat Distribution, Easily Zoned & Much Faster Recovery - Warm-Up 61 °F 55 - 65 °F 61 °F Radiant Heating
    6. 6. Why Radiant Tube Heating? <ul><li>Drop Degree Day Base with Radiant, Typically 5 Degrees F for Added Savings over air transfer systems, with lower thermostat setting. </li></ul><ul><li>Easier “Zone” heating (ex. docks vs warehouse areas) </li></ul><ul><li>Lower Energy Cost Typical 25-65% Vs Warm Air Systems. </li></ul><ul><li>Depending On Competitive System, Significantly Lower Electrical Requirements </li></ul><ul><li>Over 45 Years of Proven Savings & Effectiveness in Many Applications </li></ul>
    7. 7. Why Radiant Tube Heating? <ul><li>Greater Comfort “sandwiched” between a warm floor below and low intensity span above, when properly designed . </li></ul><ul><li>Increased Efficiency, heat “work zone level” not ceiling. Radiant does not increase heat transfer by “scrubbing” building envelope with moving air. With forced air heat stratification increases roof and exfiltration losses. </li></ul><ul><li>Faster Recovery in Applications with Active OHD’s, due to heat “reservoir” in the mass of the floor. </li></ul>
    8. 8. Test Have Shown Equal Comfort Is Maintained With Radiant Tube Heaters, Over Warm Air Systems, At A 5 Deg F Lower Temperature Setting: Assuring Real Savings By Means Of A Lower Degree Day Base. Approx 65F With Warm Air Is Equal To 61F With Radiant Tubes For Comfort
    9. 9. Types of Radiant Heating Low Intensity “ Passive” Examples: In-Floor or Panels Above <ul><li>High Intensity </li></ul><ul><li>“ Spot” Of Heat </li></ul><ul><li>Open Flame – Added Ventilation Required </li></ul><ul><li>Medium Intensity </li></ul><ul><li>“ Span” of Heat </li></ul><ul><li>Enclosed Flame & Vented </li></ul>
    10. 10. <ul><li>Fast Heat Recovery When OHDs Open-Close and/or Cold Mass Enters Bldg </li></ul><ul><li>More Effective & Easier To Zone Heat </li></ul><ul><li>Much Lower Initial Cost – Easier Construction Coordination </li></ul><ul><li>Service Issues Easy To Address – No Potential Major Repair Cost </li></ul><ul><li>Warm Floor & warm Span of Heat Above Offers “Sandwiched” Comfort </li></ul><ul><li>Easy Approach For Retrofit Applications </li></ul><ul><li>Within Certain Parameters, A Design Error Is Easy To Correct With Minor </li></ul><ul><li>Change Outs & Adjustments To Burners To Increase or Decrease BTUs </li></ul><ul><li>No Added “Boiler Room” Floor Space Required </li></ul>Radiant Tube Radiant In Floor
    11. 11. Evolution of Radiant Tube Heaters <ul><li>Original concept “little suns” many burners in series to common vent </li></ul><ul><li>Larger BTUs came along, with end burner to common vacuum pump </li></ul><ul><li>“ Unitary” heaters in various BTU’s and lengths; “Push” or Vacuum Vented </li></ul><ul><li>As numerous mfgrs entered (and some left) many variations of the above. </li></ul><ul><li>Dual firing rate heaters introduced. </li></ul><ul><li>Modulating firing rates tube heaters. </li></ul><ul><li>Ambi-Rad’s Ultra high efficiency heaters (>75% Radiant Efficiency). </li></ul>

    27. 27. The Better Dual/Hi-Low Option <ul><li>With the SmartCom Controller a given % of heaters in a facility can be programmed to fire based on a “normal” heat recovery scenario that is set within the SmartComs logic. </li></ul><ul><li>If that recovery rate is not “on target”, a second set of heaters are activated to help achieve that given recovery rate and/or extreme, prolonged low outside temperatures. </li></ul><ul><li>Dual Rate or Hi-Lows typically only do about 33% differential in firing rates, with lower emissivity at the lower rate. </li></ul><ul><li>“ Phased” firing can offer 50% High-Low effectiveness, PLUS all burners operate at full input – assuring maximum emissivity! </li></ul><ul><li>Example: Expo halls and hangars </li></ul>
    28. 28. Hangar Example 50 % High-Low, Ideal For Mega Hangar. Low Fire Most Of The Time, All Fire When Large Hangar Door(s) Open And/Or Extreme Cold Weather Occurs. 14 Systems – 6 – 130MBH Burners Per System = 84 Burners All Fire When Required (High). Low Fire Only 42 Burners Fire .
    29. 29. Expo Hall Example High Low Performance of 45% While Maintaining High Emissivity 10 Heaters Designed To Operate On “Low” Fire, 8 Additional Operate When “High” Fire Required

    36. 36. Radiant Tube Design Considerations <ul><li>Mounting Heights vs BTUs – Application Always Matters </li></ul><ul><li>Coverage/Placement – Area Heat vs Wall to Wall. </li></ul><ul><li>Reflectors: Std 45 Degs Center, With Side Approx 60 </li></ul><ul><li>OHDs on 1 or 2 Sides or Big Hangar Door (wall) </li></ul><ul><li>Venting – Roof Wall, Individual vs Common </li></ul><ul><li>Gas/Electrical/Vents – Easiest Install vs Better Coverage </li></ul><ul><li>Too Long Vs BTUs? U Tube vs Straight Tube vs Series </li></ul><ul><li>Acceptable Heat Recovery Considerations </li></ul><ul><li>Budget, LEED & Non Mechanical Design Mandates </li></ul>
    37. 37. <ul><li>Additional Design Consideration </li></ul><ul><ul><li>When heating with standard efficiency radiant heat, input load requirements are reduced by 15%. With the highest efficiency equipment this can reach as much as a 30% reduction in input. </li></ul></ul><ul><ul><li>Example : </li></ul></ul><ul><ul><li>BTU Load For Forced Air – 1,000,000 Btu/Hr </li></ul></ul><ul><ul><li>Forced Air (Front Range) 1,200,000 +/- </li></ul></ul><ul><ul><li>Std Performance Radiant Tubes .85 = 850,000* </li></ul></ul><ul><ul><li>High Performance Radiant Tubes .7 = 700,000* </li></ul></ul><ul><ul><li>* This has a positive effects not only energy savings, but front end cost of gas pipe sizing and related installation cost! </li></ul></ul>
    38. 38. <ul><ul><ul><li>Hanging Height </li></ul></ul></ul><ul><ul><ul><ul><li>General rule of thumb is for every 1’ of hanging height the unit “footprint” will equal 2’. </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Low bay applications </li></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Require more equipment to spread heat evenly in the space. </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><li>High bay applications </li></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Fewer units at higher btu outputs are required. </li></ul></ul></ul></ul></ul><ul><ul><ul><li>Contrary to common perception, it is typically not required that all floor space in an area be “blanketed” by the radiant system to achieve acceptable comfort levels. </li></ul></ul></ul><ul><ul><ul><ul><li>Perimeter applications </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Systems in low heat loss per square foot requirements such as new construction factories and warehouses typically utilize systems surrounding the perimeter with lower concentrations of heat in the center of the building where only roof load exist. </li></ul></ul></ul></ul>
