Winterizing with Instant Hot Water heater
I ran this by Thor for winterizing my 2018 Vegas 24.1, with tankless hot water system, and got approval. First, I plan on blowing out the system. Then I will fill my fresh water tank with RV antifreeze, since I never use the tank. Next, I will pump the antifreeze through out the system in both the cold lines and hot, passing through the water heater. Lastly, I will put some in bot the gray and black tanks.
