Hey there Randy!

The anti-freeze protection on the Dylux RV Tankless Water Heater # DY54FR is an automatic frost-protection feature that activates when the temperature drops below 43° F. It’s designed to help protect the water heater from freezing during cold-weather use, like when you’re camping and the temperature dips overnight.

That said, it should not be treated as a replacement for proper winterizing. The heater still installs in the exterior wall of the RV, so if the camper is going into storage, sitting unused in freezing weather, or won’t have 12V power and propane available, you’ll still want to drain and winterize the water system according to the instructions. The freeze protection is a helpful safeguard while the RV is being used, but winterizing is still the safest route for storage or extended freezing conditions.

Are you planning to use the camper during cold nights, or are you mainly looking at storage protection between trips?
