I'm in the very early stage of planning/thinking about a basement reno. in a 90 yr old house. To make this work for headroom, I will need to remove the original 3" cast iron feed/return gravity loops and homerun PAP from each radiator to manifolds. (gas boiler)
There is a lot more to consider but I would like to get a sanity check on my EDR calculation to start with.
The radiators are the 5 tube type. There are also 3 in wall radiators that were not an exact match but I'm assuming the #'s are close enough for this purpose. I used this table from Utica.

The boiler is set at 160 which is 130 BTUH per sq ft emission. (Is this the right temp. to use?)
The calculations are attached and here is a summary.
Total EDR 77,178
1st Floor
1. Living room 1 = 7,608 BTUs
2. Living room 2 = 7,608 BTUs
3. Family room 1 = 7,608 BTUs
4. Family room 2 = 8,299 BTUs
5. Dining room = 8,991 BTUs
6. Hall = 7,881 BTUs
7. Kitchen - in wall = 1,170 BTUs
8. Bath - in wall = 910 BTUs
2nd Floor
9. Bedroom 1 = 6,370 BTUs
10. Bedroom 2 = 8,190 BTUs
11. Bedroom 3 = 11,375 BTUs
12. Bath - in wall = 1,170 BTUs
How does this look?
Thanks
