Not heating the water adequately on demand, I guess is more what the guy was telling me. To be fair, I told the guy that there are times when there are as many as 6 people living in my house, so what he's projecting as my demand for hot water at any given time may have factored into what he was telling me. I just couldn't see spending 4-5 times what a tank heater costs with any chance of not being completely satisfied with it.
