Design procedure for One-Pipe System with
monofl ow tees or diverter valves
1. Select radiator hook-up sequence.
2. Determine individual heat loads.
3. Determine linear footage of wall space available for
each radiator.
4. Compute the required heat load per foot for each
room.
5. Select system temperature drop ∆T = 20, 30 or 40°F
(11°C, 17°C, 22°C) and maximum supply temperature.
6. Compute the total heat load (Q) in the loop by adding
the individual heat loads.
7. Determine loop fl ow rate from total heat load (Q) and
selected ∆T as: GPM (loop) = Q / 500 / ∆T
8. Compute the supply temperature for each room based
on the supply temperature and heat load of the
previous room and the total loop fl ow rate (GPM) as:
New Supply Temp = Previous Supply Temp - (Q room)
/ 500 / GPM
With the supply temperature computed in Step 8 and the
linear heat load in Step 4, refer to Figure 10 to fi nd the
required radiator size, or tables 9 and 10 for the total
individual radiator output if the any of the four examples
applies. Use the same ∆T value in reading from the
curves in Figure 10 as the selected value in Step 5. In
case more than one radiator is to be installed in a room,
size all radiators based on the above procedure.
