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 products that I reviewed were described very well, so that I was able to make an informed decision in the purchase of the model I needed. The ordering process was sufficient and I recieved the product in a timely manner
The unit seems very well built and was easy to install. However, temperature control/maintenance is quite variable. I've used it for a year now with no major failures. I will replace it with a storage heater but keep it in place as a back up. The fuel consumption is very efficient.
Seems to be a well built unit. I installed it less than a month ago and so far so good. Be aware that the required flow rate is .9 gal per min, if you have a low flow nozzle on your sink it will not trigger the unit to fire up. Still making adjustments, but satisfied with the unit. The price was right.
