Don Mordal on Smartrooms

  1. 1. SmartRooms Electric Radiant Heating by Therma-Ray, Inc. – Don Mordal
  2. 2. Basic Physics  Heat goes to Cold  High Pressure to Low Pressure  Hot Air Rises – Cold Air Falls  Air that does not have a difference in Temperature – Hardly Moves
  3. 3. 3 Main Factors That Affect The Heat Loss Of The Body  Convection  Evaporation  Radiation The Effective Temperature Chart accounts for Convection and Evaporation, but does not account for Radiation – Especially when the room air and its surrounding surfaces differ widely in temperature.
  4. 4. Personal Comfort  Convection 120 BTUH (35 Watts)  Radiation 190 BTUH (56 Watts)  Evaporation 90 BTUH (26 Watts) Radiant Heating warms the people, objects and surfaces in the room. Body Heat Loss – 400 BTUH (117 Watts) The Temperature Of Objects in Your Surroundings Really Does Matter
  5. 5. Cold 70  Refers to the feeling of being cold even though the air temperature is 70°  Heat is being taken away from your body too rapidly which gives you the feeling of being cold even though the air temperature is 70°
  6. 6. Convection or Radiant
  7. 7. Ideal Heating Curve The Ideal Heating Curve reflects the temperatures needed for optimum comfort and performance of the human body
  8. 8. Forced Air Heating Forced-Air systems have the greatest amount of wasted energy, with the heat collecting at the ceiling. Temperatures at the floor are considerably lower than required for personal comfort. Forced air systems are typically inefficient and uncomfortable.
  9. 9. Convective Baseboard Heating Very comparable to forced air systems, baseboards or radiators create convection currents that collect the heat at the ceiling, leaving floors cold and the room uncomfortable.
  10. 10. Radiant Floor Heating Radiant Floor Heating systems create a warm comfortable living environment that directly addresses the heat loss and personal comfort of the people in the room. Heat lost at the ceiling is drastically reduced.
  11. 11. Radiant Ceiling Heating Radiant Ceiling system also creates a warm comfortable area that covers the entire area since it is above all room objects. Especially when comparing to forced air systems, radiant ceilings are very efficient and comfortable. Floor temperatures are also higher than forced air or baseboard systems.
  12. 12. Radiant Heat - Efficiency  Precisely Controlled in each room  Greater Comfort at Lower Temperatures  Less Exfiltration / Pressurization  Less Heat Loss at the Ceiling  Lower Temperatures = Lower Cost  Energy Savings – 30%-75% over Standard Convection Systems.
  13. 13. Efficiencies vs. Other  Gas / Propane Forced Air - 85% - 95%  Electric Forced Air – 100%  Air Source Heat Pumps – 150% - 250%  Ground Source Heat Pumps – 300% - 500%  Radiant Heating - ???? –  NAHB – National Association of Home Builders
  14. 14. Types of Electric Radiant Heating: • Radiant Ceiling System • Architectural Series System • Suspended Ceiling System • Earth Storage System • Floor Joist Warming • Floor Warming System Your assurance in achieving ultimate comfort throughout any environment is complete integration of the entire system.
  15. 15. Earth Thermal Storage  System is charged (energized) when less expensive off- peak electric rates are in effect, combining the comfort of Radiant Heat with the cleanliness & consistency of electricity.  One of the most economical heating systems available by converting electrical energy into a reservoir of Radiant Warmth  The stored heat is only released when the area above it cools
  16. 16. Stud Wall Slab On Grade with Frost wall or Walkout Basment Wicking Protection: Options - 1. Radiant Reflective Insulation - No Foil can touch concrete. 2. 1" Styrofoam Insulation 3. 2 " Rigid Insulation (R-10) Concrete 4" - 8" of compacted Fill Sand Plumbing (No Debris) on top of cable. 1" - 2" of Sand - No rocks or debris Heating Panels Concrete Blocks 2" Rigid Insulation (R10) - Either inside or Outside (as shown) Concrete Footing
  17. 17. The SmartRooms Earth Storage Panels are placed evenly throughout the area to be heated.
  18. 18. The Heating panels are wired in parallel using 12 ga. direct bury wire and 3M-567 connectors.
  19. 19. Each circuit is resistance tested to verify that all the panels are wired correctly and working properly
  20. 20. Upon completion of the resistance testing, Gel-caps are used to encapsulate the connections
  21. 21. Gel-Caps are factory approved and UL tested and approved for under water and below ground connections.
  22. 22. The cold feed leads of the completed circuits shown are brought back to the service entrance – No junction boxes are necessary
  23. 23. 4” - 8” of fill or screen sand with no debris is recommended for placing on top of heating panels. Placement of sand can be done in a number of ways, including using a skidsteer.
  24. 24. Special care should be taken when placing sand to ensure no damage is done to the panels or circuit leads.
  25. 25. Sand can be tamped and a vapor barrier placed (If required by local building codes). The heating system and wires are protected by 4” - 8” of sand. Concrete can be easily poured without damaging the system
  26. 26. A resistance test should be done on all circuits after the sand has been placed and again after the concrete has been poured.
  27. 27. Circuit leads are brought back to the service entrance area.
  28. 28. The heating panels are wired to the SmartRooms relay control box and then to 240v - 20amp circuit breakers in the service panel. Typically, the ETS system is run on an Off-Peak or Dual Fuel program.
  29. 29. Tubing, manifolds, expansion tank, circulating pump, zone valves, wall space, leaks, rust, corrosion - Equals Repair, Replacement and Continued Maintenance of most or all components in a hydronic system.
  30. 30. Don’t get Blurred and confused – Save the space and skip the headache
  31. 31. The SmartRooms thermostats are connected to the control panel with Cat 5 cable and RJ45 low voltage connectors.
  32. 32. The SmartRooms Earth Storage Panels are placed evenly throughout the area to be heated.
