Total E.D.R.
Total E.D.R.
(OP)
I came across a set of mechanical drawings from the 60s and there is reference to "Tot. EDR" in the AHU Schedule under the heating coils. I found out that Tot. EDR means Equivalent Direct Radiation.
Question is how do I convert to MBH.
thanks

With an air temp of 70*F, and an avg hot water temp of 160*F would be:
(160 - 70) X 1.6 = 144 BTU
If you had steam at 5 PSIG:
(227 - 70) X 1.6 = 251.2 BTU
