Aqua-Hot FAQ Antifreeze and LTCO Service Prep

Use the Aqua-Hot FAQ page to capture hydronic model, antifreeze, LTCO, hot-water, and heating details before support.

Owner-safe checklist

• Record the Aqua-Hot model, fluid or antifreeze information if known, LTCO symptom, hot-water behavior, cabin-heat behavior, and service history.
• Save photos of the model label, control panel or display, normal-access fluid information, and service paperwork.
• Turn the Aqua-Hot system off for fuel odor, exhaust concern, leak, overheating, abnormal noise, or unsafe power behavior.
• Use Aqua-Hot support, dealer, or authorized hydronic service for fuel system, antifreeze service, internal pumps, installed power, parts, warranty, or repair decisions.
