will increasing sizes of pipe cause pressure problems for me?

matthew_rogers

now:
i have a steam boiler that i have tweeked to work great at 1/2 lb of pressure.

springtime plan:
i plan to change the undersized copper pipes that supply steam to the radiators with the proper 1.25" steel pipe.
i also plan to increase the size of the undersized copper pipe used for the equalizer and returns.

question:
will this new and increased flow provided by re-building it to manufacture specs require me to tweek my pressure settings again? or is there something im not thinking of.

No, it won't affect it. The pressure at the radiators will be very very slightly greater, but it won't even be a measurable amount.
