I had this model tankless water heater installed in my home in 2008. It was the Bosch Power Star model. Within two months it stopped heating water. Bosch replaced that heater under the warranty. I had to pay an electrician again to install it. In June of 2015 one of the two elements in that heater burned out. Bosch replaced that element (under warranty.) Again I had to pay electrician to install that part.

One month later that heater stopped working altogether. After some diagnostic testing with an electrician (that I once again had to pay) Bosch informed us that the motherboard to the unit had gone bad. That part was replaced under warranty. That part arrived in December of 2016. Once again I called & paid the electrician to install it. That day one of the elements in the heater exploded (destroying the unit completely and heavily damaging the bathroom along with it. It sounded as if an airplane had hit the house. I contacted Bosch looking for compensation. I was offered a new unit & nothing else. I now have a completely unusable bathroom.

Needless to say, I do not commend any model of Bosch tankless water heater.
