A Enter the name of the room. The room may
have more than one loop.
B Room setpoint temperature is normally
65°F (18.3°C) for radiant floor.
C Zone is equal to thermostat. D Enter the amount of square footage used in
the room.
E Enter the “Floor Unit Load to Room” value
from ADS printout (upward load).
F Enter the “Floor Unit Load” value from ADS
printout (total load).
G (Row E/2) + Row B = floor surface
temperature. Do not exceed 87.5°F /30.8°C for all floors (exception: wood floor limit is 80°F/26.7°C).
H The only tubing size available for Quik Trak
is
5
⁄16" Wirsbo hePEX.
I Refer to Appendix D for floor covering
information.
J Indicate differential temperature
(20°F/11.1°C for Quik Trak).
K Tubing o.c. distance is 7" for Quik Trak. L Use information from Rows E, I, K with
Appendix E to obtain the supply water temperature.
M Enter the length of tubing installed within
the room (i.e., active loop).
N Enter the length of the tubing from the room
being heated to the respective manifold.
O Use formula: (Row M + Row N) = total
loop length.
P Use the values in Rows F and M with
Appendix F to obtain the flow per loop.
Q Use the values in Rows O and P with
Appendix G to obtain the head pressure per loop. Choose the appropriate solution (water or water/glycol solution).
R These cells are calculated after the design
is completed. Use the formula: (current loop value in Row O x 4) / longest loop length on the manifold.
S Enter the number of panels.
(For 7" o.c., multiply Row D by 0.386.)
T Enter the number of returns.
(For 7" o.c., multiply Row D by 0.043.)
U Enter highest temperature from Row L. V Add and enter all values from Row P. W Enter highest value from Row Q.
