A well-maintained hydronic heating system provides reliable performance even during the harshest winters. Heating maintenance professionals know that top quality materials are critical to achieve superior performance. That’s why contractors depend on Hercules® Maintenance and Stop-Leak Products. They are formulated for high performance and developed with both the user and the environment in mind. Hercules “clean and friendly” furnace cement is the latest example of this commitment. Its patented formula is the first and only to meet OSHA’s requirement of less than .1% crystalline silica.
07Heating Chemicals & Antifreeze
What are the differences between virgin propylene glycol and reclaimed/recycled propylene glycol?
Virgin propylene glycol has never been used previously. Some boiler manufacturers state in their warranties that antifreeze made with virgin propylene glycol is required or the warranty is voided. Recycled propylene glycol is captured and cleaned after use (mainly for de-icing aircraft). It is then considered a lower grade of propylene glycol and may still contain other ingredients even after cleaning. Hercules Cryo-Tek antifreeze is made only with virgin propylene glycol.
Are there specific products for aluminum boiler systems?
Yes. Use Cryo-Tek 100AL antifreeze for boilers with aluminum heat exchangers. Sludgehammer Universal Corrosion Inhibitor and Sludgehammer System Restorer & Noise Reducer is compatible with all metal heat exchangers, including aluminum.
What is the warranty on the pump that comes with the Haymaker Kit?
The pump has a one year warranty from date of purchase.
