I purchased this Bosch AquaStar 240FX, quite expensive water heater based on Bosch reputation for quality. I wanted to do my part to save energy, so spent more than twice
the cost of a conventional water heater. It functioned well for 2.5 years,
then stopped working. I thought "no problem", the warranty was a reasonable
5 years, similar to a "normal" water heater. I failed to read the fine print however. 5 years was for the heat exchanger ONLY. The rest of the parts were
warrantied for ONE YEAR ONLY!?. The failed part, the main circuit board was FIVE HUNDRED DOLLARS!!, almost half as much as a new unit.
Even the cheapest conventional water heater lasts more than a couple years. This is my second bad experience with Bosch, as I had an early
failure of a dishwasher as well, where the replacement parts far exceeded
the value of a two year old appliance. I'll not consider purchasing another Bosch product. Beware an advertised warranty length to be sure it's on the whole product before purchase. To add one more complaint, I was on hold for over 2 hours for tech support to diagnose the problem
