ANSI/ASHRAE/AHRI Standard 155 provides a method of test for rating commercial space heating boiler systems, with the objective of providing a means to determine the seasonal efficiency of individual, modular, and multiple boiler systems having various means of staging boilers to meet the building load, various boiler outlet (supply) or boiler inlet (return) water control strategies, and various pumping strategies, when applied, to meet the load of a particular building or prototype building in a particular climate. This standard provides test procedures and calculation procedures that allow a full performance map to be created for an individual boiler from the test results.
