In Reply to: Boiler size for space size posted by Steve McLaughlin on March 27, 2006 at 11:43:41:
: I have a 4,000 sq ft commercial building. The steam radiators are old and hard to replace. There are 2 floors of approx. equal area. Can I cap the second floor radiators, remove them from the system, essentially halving my number of radiators and use the same boiler. (I can convert to electric baseboard.) I suspect there is a pressure excess getting in my way but I wonder if there is a way to reduce that output. I have a Utica Starfire 3.
: Thanks for any advise. Steve
Just curious, what kind of controller does that boiler have? What is the capacity (KG/hr)at what pressure? What is the operating pressure? How many radiators are in total?
I'm not an expert for sure on low pressure heating boiler systems but I would think that you would be fine to cap off your second floor with regard to your boiler operation. You might run into trouble if you are not altering the heating circuit properly. Make sure the 1st floor rads have a complete circuit back to the boiler and the top floor is completely isolated from the system so that no condensate is being trapped up there. That boiler you mentioned, how old is it? I assume it is a new one.
