I've had a instant on here for several years now and it works great. cut my electric bill by 30%. My problem is at my cabin in NC. The water temp out of the well is 57 degrees. The heaters I would use there would be gas as the cabin only has a 100 amp service. A single instant on would not work, max temp they will increase temp is 30 degrees. I am pretty certain that if I put 2 in, in series that I could get the temp I need but can't get a peep out of any of the manufactures through Email. Just wondering if anyone here has had any experience with something similar.

Why would you need any hotter than that?
I bet you can pinch a penny til it screams.
Rinnai RL94 is the model number, can be set hotter if you want, and runs on propane. No problem running two showers and still using water in the kitchen.
Have never run out of hot water, even with lots of people (15+) getting ready for an event.
I set up mine here in S.FL so I can do a diluted citric acid flush on it when I get around to it. Funny it's the same concentration of acid I use to sonic clean my shells for reloading.
