Glycol Heating System: Is It Better Than Water?
What Is a Glycol Expansion Tank? A glycol heating system is a type of closed-loop hydronic system that circulates a water-glycol mixture through pipes, boilers, or radiators to transfer heat efficiently, safely, and reliably. These systems are especially valuable in cold environments where freeze protection is critical. Why Is Glycol Used in HVAC Systems? In HVAC systems, particularly those exposed to low ambient temperatures, glycol serves as a safeguard. It’s mixed with water to create a heat transfer fluid that
