Different heating elements are made of different materials. By changing our heating elements to stainless we could offer the customer a better product. Zinc (galvanized steel) and copper are both “noble” metals and will not corrode much, copper will accelerate corrosion in zinc (and steel) even when separated by water, by “dissimilar metal corrosion”. Stainless will not react in this way. Made for Water distillers.
Does not include the gasket (o-ring)
