Glycol Help Text



Glycol or anti-freeze protects your heating system from freezing. We do not recommend glycol in most residential or commercial applications. We do recommend glycol only in systems that will be left for extended periods of time such as; workshops or vacation homes. Glycol is required for systems that will operate at below freezing temperatures like snow melting applications.

We recommend buffered Propylene Glycol in a 30% to 50% mix for optimal system performance.

Select Yes for Glycol if you believe it is necessary for your project.
