zero customer service
had the hot water heater for 7 months, stopped working. contacted customer service who advised to contact a approved plumber to repair it. there's not one of their approved plumbers near by to service it and when I told the company they basically said we apologize and can't help. wow
It is heavy.
The water heater works great. It was not too hard to install.
