Need help rating these radiators.
Hello to all. First of all Thank you to Dan Holohan for the EDR book.
It's amazing. I'm a property manager of a church in Chicago and I'm
trying to determine the ratings of our radiators in our sanctuary.
We are going to replace the steam boiler with a geothermal heating AND Cooling
system. I've been told by one contractor we need 40 tons, 50 by
another, and 30 by even another. So I bought the book EDR and it's
perfect. I'm going to determine the actual heating capacity that we
have now and compare it with the quotes.
SO, for all the radiators (this is a 2 pipe steam system), I can easily calculate the total square foot
of radiation. BUT there are 8 radiators that are fin type radiators.
They are in an enclosure, (similar to a national cabinet enclosure lets
say). However, in my case, there are also blowers on the radiators.
Basically squirrel cage fans to blow air over the fin type radiator to
transfer heat more quickly.
My question: Is there a way to calculate how much BTUs I'm getting from
these? Can I calculate my CFMs on the blowers and use this somehow in a
Please advise! Any help is much appreciated.
