In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Have any contractors found commonality between Boiler Manufactures piping Diagrams, minimum pipe size and circulator sizing on the boiler primary loops.
Like those boilers that have common heat exchangers HTP Elite, Burnham ES, Peerless Purefire etc with the Giannoni type? Sometimes we are forced to substitute one for another based on availlablity, It would be helpful for me if any one logged the requirement differences between each based on common btu output
