Furrion Tankless Water Heater - Cold Weather

Will air blow out the water in the mixing bowl?

While I can't say for certain, it would seem to me that if only the hot water feed were open, then yes, assuming sufficient pressure, all of the water in the tankless water heater could be blown out (including the mixing bowl). There have been reports on the forum of folks who ONLY winterize by blowing out their lines and have had no damage. Personally, being a belt and suspenders kind of guy (if one goes the other will still hold up your pants), I first blow out with my compressor and then follow with the pink stuff. Fingers crossed, that approach has worked well so far on my tankless water heater.

Thanks , yes I guess I’ve been lucky . What lines and where do I blow the air ?

That’s a picture of my water heater but it’s rotated for some reason

Check your manual, it may be covered under Winterize.
