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.
I installed this today.It took me all day and an extra trip to Lowes for different parts. I took my first shower and it was great having hot water thru the whole shower. Our old water heater was almost 30 years old and could not take a shower fast enough before running out of water.
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
