Bests & Worsts Reviews from Amazon

As long as nothing goes wrong with this unit, you'll love it. If it fails for some reason, you'll just get the runaround from customer service, and all that love will disappear. This water heater had some great features compared to the Bosch it replaced, and it worked well for a few months. Then it sprung a pinhole water leak in the heat exchanger tubing. The leak was right on the bend in the tubing, a natural weak spot, and appears to just be where the water pressure wore away at it until it broke. My husband removed the unit so we could at least restore cold water flow until we could get a replacement. I e-mailed the customer service address in the manual to ask how you go about a warantee exchange. They replied by e-mail that I would need to call them, because they had questions. My husband called customer service. Their brilliant analysis was that the unit had to have frozen from cold air coming down the vent on a 31 degree night. Really? Inside the warm house? Come on! If that is the case, what is going to happen to the unit on the other end of the house when we get to the actual cold weather, below zero? I guess we get to look forward to some major water damage. They couldn't stand by their warantee, because it just had to be our fault that their product failed, but, hey, they will kindly sell us a replacement at a discount. What kind of warantee is that!?! Buy at your own risk- maybe it will work great and you'll have no problems. But if you have a problem, the warantee isn't going to apply, and you'll be stuck with buying a replacement. Update: We never were able to get this company to back their warantee, and got tired of arguing with them. We ended up having the pinhole repaired, and that lasted about a month. Then, a new pinhole leak started in another place in the tubing. Water sprayed all over the electronic connections, ruining them as well. We've had it with this piece of junk, and won't be repairing it again just to wait for the next leak. Do not waste your money on this product!
