How Is A Boilers Kilowatt (kW) Rating Determined?
The amount of heating surface determines the kilowatt rating of a boiler. • Calculate the kilowatt rating by multiplying the heating surface in square metres (m2) by 10. • 1 m2 of heating surface = 10 kW. (10 m2 = 100 kW, 100 m2 = 1000 kW, etc.) Go To Top How Do I Find The Heating Surface Of My Boiler? • Check the manufacturer’s nameplate. The heating surface in square metres (m2) may be listed. • Check the ABSA Certificate of Inspection for the heating surface in square metres (m2). • If you cannot find the heating surface, contact ABSA. Have information available, such as: the Alberta Identification Number (A-number), the Canadian Registration Number (CRN), and/or the name and address of the previous owner (if applicable).
