Air Handler Sizing

Andy_11

Andy here from Wagner Century Oil. I've come across a situation that I would really appreciate your input & advice on. I'm doing an estimate on a house that has steam convectors and a G.E. steam air handler. How do you size this air handler for correct steam load, as we would like to replace the boiler? There is no rating plate. What should I watch for when installing the new boiler other than near boiler piping for this air handler? Also, should this unit develop troubles, do they make new ones or should we convert to hydronic air handler using loop from boiler? Thank you in advance for any information and/or ideas that you may have.

...if there's a CFM rating for the fan. If you have that number, and the temp rise you need for the air across the coil, it's a simple calculation to figure out how much steam is required.
