No Sir, the fresh water loop that provides hot water to the coach.
Put fresh water antifreeze into a bucket. Connect a pump to the fresh water hose inlet and the bucket. Turn on pump and open the utility HOT Water facuet valve. When pink comes out of the facuet, the Aqua Hot fresh water loop is winterized.
OR, keep electric elements ON with the grid or generator. As long as the Aqua Hot coolant is hot, the fresh water coil will not freeze and split. But, if the coolant goes below 32 degrees F, the coil is in trouble. The coolant is still liquid but the water will freeze.
I have replaced six heaters whose owners allowed the coach to sit turned off in freezing conditions with no fresh water antifreeze.
