OCPS Southwest Middle School Boiler Room Renovation

OCPS Southwest Middle School Boiler Room Renovation

Project Summary

When OCPS Southwest Middle School determined that their current heating hot water system needed a more efficient overhaul, they contacted Thermal Tech, Inc. to perform a system evaluation. The outcome was the recommendation to install more efficient and reliable equipment to meet the needs of the application.

KN boiler side croppedThe Challenge – An aged inefficient heating hot water system which included:

  1. An existing cast iron boiler operated at low system water temperatures, which were conditions not intended per the design.
  2. A heavily corroded flue venting system.
  3. An oversized system pump.
  4. An expansion tank with a ruptured internal butyl diaphragm bladder.
  5. Air and dirt present in the system distribution piping.

The Solution – The application of state of the art equipment which improves the operational efficiency of the existing system.

  1. wilo pump 3 croppedThe ATH KN-Series boilers Model KN-26 HHW high efficiency condensing boiler model takes the heat-retention and durability of cast iron and couples it with the energy savings of a fully modulating burner. A new double wall stainless steel internal/outer material special gas venting system was installed to support this new boiler.
  2. The Wilo Model Stratos GIGA 2.5/3-87 2-1/2″ is a high-efficiency space-saving inline circulator with ECM technology that is designed for use in hot water heating systems, air conditioning, closed cooling circuits, and industrial circulation systems.
  3. Spirotherm Air & Dirt Separator Model VDT500FA Spirovent® inline coalescing type air and dirt.  A new bladder diaphragm-type expansion tank sized for the existing system volume was installed.

The Results – Through applying the latest technology, the following results were achieved:

  • Gas savings of $10,800.00 per year.
  • Electrical savings of $5,615.00 per year.
  • Maintenance saving priceless due to no dirt or air in the system.

Project Completion April 2015
