This field study involved long-term monitoring at 11 buildings representative of commercial condensing boiler installations in Minnesota. Key characteristic variations were building type (e.g. education), boiler system size, boiler system piping arrangement, type of controls, and whether it was a condensing boiler system exclusively or a hybrid system.
