Boiler size? Is it correct?

Steamhead (in transit)

for the baseboard loops, you need to know the heat losses of the areas they serve. If you click on "heat loss calcs" in the lower orange bar above, you can get a free, easy-to-use program from Slant/Fin that will do this for you.

The "Bell & Gossett" approach sounds like he's going to use a different type of heat exchanger. But you need to be sure of this.

He's dead wrong about the copper steam piping. Why not get in touch with Dunkirk regarding this? Their Web address is

Boiler size..is it correct? Dunkirk PVSB-8D

My Dunkirk PVSB-8D has the following ratings:

262,000 btus AGA input 214,000 heating capacity 161, net I=B=R rating 671 Net I=B=R rating sq. ft. radiation.

My contractor is telling me that it is correctly sized since I have 275 sq ft radiation of steam radiators, and 100 feet of hydronic baseboard radiators (I don't know how to measure the radiation requirements of hydronic baseboard radiators?) running off of the same boiler, using a direct heat exchanger. He also mentioned that he needs to remove and eliminate the heat exchanger and repipe the hydronic system using the "Bell and Gosett" approach (does anyone know what that is), since the steam unit is clogging the heat exchanger with too much crud.

Additionally, since he just installed this system for the previous owner of my home in April of this year, he feels like I was not the one who hired him. He sees nothing wrong with the fact that he used copper piping on the header (see photos earlier in this thread) and also piped the header without an equalizer or Hartford Loop and with the takeoff to the steam main in the center rather than between the riser and the equalizer.

Does anyone know if any building codes may have been violated so that I might be able to pressure him to fix things? I expect to talk with the building inspector in my village tomorrow, but any advice would be greatly appreciated. I don't know how to convince him to fix it with minimal cost to me?
