: Experience is the best. Make sure they follow the piping diagram in the I & O manual. Steam must be piped and sized properly for beat results. More steam jobs have gone bad due to oversized steam boilers.
: Here is a webpage with a lot of steam info from piping to FAQ.

Dan Holohan of Heatinghelp.com says that the most important thing when sizing a replacement boiler is not a heat/loss calculation for the house but to calculate the edr for each cast iron radiator and then add them all up to get the amount of btus you need for the steam boiler. Does that sound right?
Thanks
