Yes — for topping up a glycol floor heating system, you should use a propylene-glycol–based hydronic heating antifreeze, not automotive antifreeze or standard pink RV plumbing antifreeze.
This product (Premium Heating System Antifreeze) is typically designed for closed-loop RV heating systems.. It can be used to top up the system as directed by the heater manufacturer and to the product's mix ratio. We would recommend reviewing your heating system's manual and be sure to read product instructions prior to use.
