Moderate Repairs

• HCFV-1 Heating, Cooling, Fireplaces and Ventilation - Water Heating Systems:

  A Raypak boiler equipped with an economizer was observed servicing the commercial car wash. An economizer captures waste heat from the boiler’s flue gases and uses it to preheat incoming water, improving system efficiency and reducing fuel consumption. This type of equipment is common in high-demand environments such as car washes, where substantial volumes of hot water are required.

  
  

  The system could not be tested at the time of the inspection because utilities were off, and its operational condition could not be verified. Both the boiler and economizer units also appear to be original to the building and show rusting at the base, which may indicate age-related deterioration and potential end-of-life considerations.

  
  

  Recommendation: Have a qualified boiler technician evaluate the boiler and economizer once utilities are restored to determine their operational status, assess the extent of corrosion, and provide recommendations for repair or replacement as needed.

• HCFV-2 Heating, Cooling, Fireplaces and Ventilation - Vents and Flues:

  CORRODED B-VENT ABOVE THE ROOFLINE

  The B-vent flue for the appliance was observed to be corroded above the roofline, indicating deterioration of the vent material. Corrosion at this location can compromise proper venting of combustion gases and may allow water intrusion or flue-gas leakage. This condition requires correction.

  
  

  Recommendation: Have a qualified heating contractor further evaluate the flue and replace the corroded section as needed. Installing the proper vent cap design can help reduce future corrosion by minimizing water entry into the top of the vent pipe.
