Alex,
Thank you for your question. The Caleffi 252159A is a thermostatic mixing valve that has a mixed outlet temperature adjustable from 80-150 degree F. The maximum inlet water temperature is 180 degree F and it is only ratered for use with water. The specificaitions do not inducate use with glycol. It requires a minimum 30 degree delta T between inlet water temperature and mixed outlet temp. I attached the technical brocure for you to review and you can contact Caleffi tech support anytime to discuss or email techsupport.us@caleffi.com.
