Chuck,
If you are going to leave the Aqua-Hot running (either electric or diesel), you will be fine with what you did. HOWEVER, if you shut it down and it freezes, you'll be in big trouble, without proper winterization with the pink stuff. If the internal coils freeze and burst, which will happen quite easily if allowed to freeze, the unit CANNOT be repaired. You'll be looking at a $10,000 bill for a new unit.
We also have it in an enclosed insulated garage that is attached to the house....2 walls use the house walls.....and one wall is along another 40 ft garage.....so only the door really faces the outside.....but neither garage is heated.....Chuck
