I love the water heater. Extremely disappointed in the Factory Pure Co. I ordered a product that was not the right one. Factory Pure wants to charge me 20% of cost for a re-stock fee, plus I must pay shipping both ways. OUTLANDISH!!! After waiting over a weak to receive the wrong unit and then be charged to return it, BAD BUSINESS PRACTICE. I was forced to do business with Amazon, which I have avoided for 30 years or so. I will never do business with this company again.
