Aqua-Hot 400P propane/electric prep

Use the official Aqua-Hot 400P product page to collect propane/electric model, zone, hot-water, and service-call details.

Owner-safe checklist

Record the Aqua-Hot 400P model, serial details, controller state, zones affected, hot-water symptom, cabin-heat symptom, energy-source selection, and RV make and model.
Shut the unit down from normal controls and leave the area if propane odor, alarm activity, overheating, or fluid leak appears.
Use Aqua-Hot, an authorized service center, dealer, or qualified Aqua-Hot service for propane equipment, heat zones, installed power, parts, or service decisions.
