I had a Bosch tank-less water heater prior to purchasing this Rinnai water heater. The Bosch lasted only 8 years and actually had problems from day one of the installation - overheating, turning off in the middle of a shower, leak from the copper burner tank, etc... This Rinnai water heater has been rock solid from day one, extremely efficient and has worked flawlessly for the past year supporting the demands of 5 users in my household. This unit supports at least two showers simultaneously and more. I would definitely without hesitation recommend this product to anyone with a large family that wants an efficient unit without sacrificing the hot water throughput.
The water gets hot within a few seconds. We can take showers, run the dishwasher, run the washer, and still not run out of hot water. The power usage is at most 60 watts.
this is a good product but must say the directions are not good they directions for dummies because I had to send email and call them to have help to get this thing working correctly but they were very helpful in doing so the manufacture that is I would recommend it to others that don't have room for a large hot water tank and the cost is cheaper than a hot water tank
