Bests & Worsts Reviews from Amazon

I wish I had never bought this product. I've had to replace the heater elements twice in about 3 years at cost of about $250 for the parts ($85 for 2 elements) plus labor for each incident. I have sunk about a $1,000 into this unit and more failures are to come. The elements seem to be made of copper, and they corrode very easily. Ecosmart told me that I should have removed the elements and soaked them in vinegar to remove mineral buildup every six months or so, which I did not know until just now. No water heater should require such intense and frequent costly maintenance. My plumber says the elements should be made from a metal that does not corrode so easily such as stainless steal instead of copper. Do not buy this very poor unit if your water supply isn't mineral free. I suggest sticking to a traditional tank electric or even better yet gas water heater like I used to have because they are far less expensive and they are usually guaranteed to last 10 to 20 years without trouble. Ecosmart does not guarantee its elements at all probably maybe because it knows they are prone to failure. They should at least tell customers with minerals in their water not to buy its product.
