: one contractor uses "schedule 40 steel near – boiler piping with cast iron fittings from new boiler to existing system main piping and condensate return piping as per local codes and manufacturers’ instructions and piping schematics."
: +++ Call the contractor that made this statement as it is proper procedure and can be verified later. The other contractor is saying he'll do it any way he likes without saying that he'll do it right.
What part has you say that? Because he says he'll do it according to local codes and manufacturer's instructions? FWIW, I'd be doing this job with permits and inspections, so I know it would at least meet local codes. If I asked him to also follow manufacturers instructions would they then be equal?
What about using using copper piping? Contractor 1 speaks only of steel while contractor 2 speaks of steel and copper. Which should be used in those applications, copper or steel?
I am giving the second guy every opportunity here because he is less expensive AND widely recommended by homeowners in the neighborhood.
: They are equivalent in quality. As to whether they are approximately the same size, it doesn't make a difference unless they are the right size boilers to fill the system and the radiators completely with steam. So ultimately the installer has to make sure they are big enough to do the job.
Sure, I only asked because if the two were in agreement on size I'd be more comforted their calculations were correct than if they were not. Both measured every radiator (and counted fins) in the house.
Your help is greatly appreciated!
