Balancing Radiators

ToddB

To date I have balanced my single pipe system radiator venting unscientifically by comfort/feel, but would like to compute riser and radiator air volumes and see if I can make any improvements. I am using Hoffman 1A and 1B adjustable vents on all radiators. I understand that there are factors to convert from EDR to radiator air volume, but cannot find those factors in any of Dan's books that I own. Any help would be appreciated.

Venting e-Book

You need the balancing e-book available from the shop. Well worth the investment.

It has values for volume of air in lengths of pipes and for different types of radiators.



Good luck.

Own it

I do own this book. Reference is made to charts 1 & 2 from Dan Holohan's “Dead Men Steam School’s” workbook when discussing air volume in risers and radiators. I can't find the volumes that you are referring to in this book.

Values

In my copy the values are listed on page 14 (of 16) under 'How much air is in a pipe?' and 'How much air is in a radiator?'.



I don't know if there's been an update to the document since you bought it.

Explains it

That explains it. My copy is 15 pages with pages 14 and 15 being an update for the winter of 2005/2006. I think that I purchased the book in 2010.



Do you know of any other sources of air volumes?
