How to determine the date of production/manufacture or age of FHP® HVAC Systems.

The date of production/manufacture or age of FHP® HVAC equipment can be determined from the serial number located on the data plate.

Parent Company:  Bosch Thermotechnology Corp. a Subsidiary of Advanced Thermal Technologies

Example serial number styles/formats found:

  • Style 1: 63036333-00-7080-3241
  • Style 2: 253000-08065-00040-77470007354
  • Style 3: EG013220D

 

Style 1: 63036333-00-7080-3241

Description: FHP® serial numbers for boilers and tanks each consist of 18-27 digits with clear, consistent patterns divided by dashes.
The Year of Manufacture can be determined by using the 1st numerical digit of the 3rd series of digits.
The Day of Manufacture can be determined by using the last three digits of the 3rd series of digits.  These three digits represent the Julian date.
Using the ANSI or CSA standards to determine approximate Year of Manufacture.
Most manufacturers today are required to include the manufacture compliance standard on the data tag. For the U.S. the compliance standard is typically from the American National Standards Institute (ANSI). For Canada, a common standard compliance is through the Canada Standards Association Group (CSA). Many times both standards are listed. Regardless, the specific standard will normally be listed on the data tag/plate and followed by the YEAR of the last revision (often the year is placed in parenthesis or follows the hyphen after the specific standard number). As these standards are revised or renewed approximately every 4 to 6 years, one can reasonably estimate the year of manufacture within 4-6 years from (after) the standards date.

Style 2: 253000-08065-00040-77470007354

Description: FHP® serial numbers for boilers and tanks each consist of 18-27 digits with clear, consistent patterns divided by dashes.
The Year of Manufacture can be determined by using the 1st & 2nd numerical digit of the 2nd series of digits.
The Day of Manufacture can be determined by using the last three digits of the 2nd series of digits.  These three digits represent the Julian date.
Using the ANSI or CSA Standards can also be used to determine the approximate Year of Manufacture.
