Winterizing hydronic heat system

[Roadweary]

I can't seem to find much useful information on winterizing my Oasis hydronic heat system in my 2013 Ventana. I'd like to use compressed air on my coach and wonder if I should somehow bypass the Oasis boiler. It has a bypass function and also a bypass pump but I'm not sure how either of those work. I'm wondering how others winterize their system. Thanks.....

In the Oasis manual it states: "Note that any domestic water in the Distribution Module will freeze in cold temperatures and will damage the internal parts. The Distribution Module and all associated components must be completely drained and emptied of any domestic water before freezing temperatures are encountered."

I run pink through all hot water lines, and that gets it into the Oasis Distribution Module. Afterwards, you could drain the domestic water from the module. Last year, I let the pink anti freeze in the Distribution Module and all was well in the spring.

Thanks for the replies and links. It sounds like blowing out the water lines won't suffice. I'm not thrilled about using the pink antifreeze but from what I've read so far, it's about the only answer. I live in a desert area but we can still drop into the teens on rare occasions so maybe I'd better play it safe.

Do NOT leave ANY water inside your Oasis hydronic heating system otherwise be prepared to shell out thousands of dollars for a new unit next springtime.

Use the RV antifreeze to fill up the hot water lines inside the Oasis unit.

Air will not work!

Post above is 100% correct.

Great advice and duly noted. It's hard to ignore experts from Minnesota and Alaska when it comes to winterization.
