You can use a Aqua Hot for FURNACE operation after it is winterized. There is no danger or damage than can happen when winterized. There is nothing to "expand". Doug
From page 107, "NOTE: The Aqua-Hot can continue to be used for interior zone heating once the domestic water heating system
has been drained and winterized....with FDA-approved “GRAS” RV Antifreeze". As mentioned, winterized per instructions-no problem using for heating.
And there's my answer. Thank you.
