1. SmartRooms Electric Radiant Heating
by Therma-Ray, Inc. – Don Mordal

5. 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

6. 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.

7. 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

8. 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°

9. Convection or Radiant

10. Ideal Heating Curve
The Ideal Heating Curve
reflects the temperatures
needed for optimum comfort
and performance of the
human body

11. 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.

12. 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.

13. 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.

14. 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.

15. 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.

16. 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

17. 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.

18. 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

19. Stud Wall

2. 1" Styrofoam Insulation
3. 2 " Rigid Insulation (R-10)

20. The SmartRooms Earth Storage Panels are
placed evenly throughout the area to be heated.

21. The Heating panels are
wired in parallel using
12 ga. direct bury wire
and 3M-567 connectors.

22. Each circuit is resistance tested to verify that all the
panels are wired correctly and working properly

23. Upon completion of the resistance testing,
Gel-caps are used to encapsulate the connections

24. Gel-Caps are factory approved and UL tested and approved
for under water and below ground connections.

25. The cold feed leads of the completed circuits shown are
brought back to the service entrance – No junction boxes
are necessary

26. 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.

27. Special care should be taken when
placing sand to ensure no damage is
done to the panels or circuit leads.

28. 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

29. A resistance test should be done on all circuits after the sand has
been placed and again after the concrete has been poured.

30. Circuit leads are brought back
to the service entrance area.

31. 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.

32. 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.

33. Don’t get Blurred and confused –
Save the space and skip the headache

34. The SmartRooms thermostats are connected to the
control panel with Cat 5 cable and RJ45 low voltage
connectors.

35. The SmartRooms Earth Storage Panels are
placed evenly throughout the area to be heated.
