A BoilerMagXT magnetic filter was recently installed as part of a boiler replacement project at a school in Greeley. Within just two days of operation, the system demonstrated significant effectiveness in removing accumulated black sludge from the hydronic system.

Problem

Older hydronic heating systems—especially in institutional buildings like schools—often contain:

• Magnetite (iron oxide / black sludge)
• Corrosion byproducts
• General system contamination from aging piping and components

These contaminants can lead to:

• Reduced heat transfer efficiency
• Increased wear on new boiler equipment
• Higher maintenance costs
• Risk of premature system failure

When installing new boilers into existing systems, this contamination poses a serious risk to performance and longevity.

Solution

To address this, a BoilerMagXT magnetic filter was installed during the boiler replacement.

• System water was circulated through the BoilerMagXT continuously
• The unit was flushed every two days to remove collected debris
• This flushing schedule will continue until visible buildup decreases, followed by ongoing maintenance flushing

 

After just 48 hours, the BoilerMagXT had already captured a large amount of contamination. This highlights how much harmful debris was in the system—and shows that installing a BoilerMag during boiler replacement is essential for protecting performance and extending system life.

 

Installing a BoilerMag provides several critical advantages:

      Protects new equipment

• Prevents black sludge from damaging newly installed boilers and components

      Improves system efficiency

• Cleaner water allows for better heat transfer and overall system performance

      Reduces maintenance costs

• Capturing black sludge early reduces future service issues and downtime

      Extends system life

• Minimizes corrosion and wear throughout the system
