water temp fluctuates like others have stated, seems to also be related to water pressure. I upgraded every piece in my plumbing system, even installing pressure regulator as suggested in manual and still getting fluctuation. Which when your lathered up and it goes scalding hot or freezing cold in a small stand up shower its not nice. This would probably work better if you lived in an area with city water. Well water on this unit is not advised...
Going to attempt to return this item and get better name brand online since its not offered in store :(
My only advantage I have is it was clearance priced at my store to $244.06 and I see why it was now...
No, I do not recommend this product.

This thing is amazing! I was hesitant at first, as I live in upstate NY, where it gets really cold in the winter. I was worried about it being able to get the water hot enough - if you have any doubts, leave them now. I don't have the water heater turned up all the way, and it's so hot coming out of the faucet I have it barely past the middle point to take a steaming hot shower. I think the reason it's only rated for what it is, is that if someone were to get less, because of a high load, the company cannot be held liable. Believe me though, it is more than sufficient even in the coldest weather. Incoming city water, even in winter, usually isn't lower than 45 in the ground, fyi.
Easy to install as well - you need 200A service to your house, 6 empty spots, and an afternoon with a helper, and you can install it yourself.
Yes, I recommend this product.

I like instant on water heaters and have used them for years with no problems. Unfortunately, this brand is of poor quality, and the output temperature fluctuates wildly. Other times, hot water flow stops and then resumes a few minutes later for no apparent reason. That's not fun when you're lathered up! And worse yet, this brand does not last long; it quit after 4 years. Yes, it's under warranty, but the warranty does not cover new installation; warranty does not cover the hassle, and I would rather not have to replace expensive appliances every four years.
No, I do not recommend this product.

read other people's review was kinda nervous before ordering it, so many crazy reviews saying its not enough hot water, and this and that problem. of course all this install is best left to professionals. had our electrical updated to 220 and ran 120amp to the tankless, runs perfectly fine hot water in this nice cold winter that we having already. water coming in 45F and i have perfectly hot 130F. i'd say to those who doesn't have hot water please turn on the temperature control to the max! cause the professional installer did the opposite and turn it to the otherside to the lowest setting temp. due to this tankless not having a temp gage. we can't tell what temp it is. that's probably 1 of the only thing i would like to have vs. the dial we have. also i ran both the sink and shower at the same time during this nice cold winter , still have enough hot water for showering with out the cold water. :D enjoy many days of hot shower to come

What a fantastic appliance - exceeds my expectations. Easily supplies endless hot water to our whole house (2 baths + kitchen). One caveat: make sure you have the capacity in your electrical panel for 3 40amp 2 pole breakers, and that you have 200amp service to your panel.
Yes, I recommend this product.

Pro: We have a family of 4. The unit provides instant hot water continuously.
Con: SW USA has hard water. Recommend a whole house water softener if you intend to purchase a tank-less water heater.

Installation is easy for the plumber and the electrician.
However the cost to have more circuit breakers cost almost as much as the unit.
I would recommend this unit if you need the space.

I replaced our old tankless heater with this one, and it works so much better! The temperature does fluctuate a little bit, but it's within such a narrow range, you almost don't notice it when you're taking a shower. Nothing like the old one!!!
P.S.: Works great even with the cold Maine well water.
Yes, I recommend this product.

This is a poorly designed product.
The manufacturer recommends this for cold climates, but the unit is unable to produce acceptably hot water at the full output temperature setting for well water measuring 60 F, well within the specified input.
The unit turns on at a flow of 1.25 gpm, not 0.8 gpm as the spec sheet says. That is where it turns off. The result is that my bathroom sink (and most small sinks) will never see any hot water from the unit. If your sink does have hot water it will only be at full on. That is simply not energy efficient.
Technical support is abysmal. The personnel are trained to turn any problem back onto the customer and try to ignore the design flaws. Their tech hung up on me, then didn't answer the phone when I called right back.
By the time I had figured out all these problems, it was too late to return the unit. Don't let this happen to you.
No, I do not recommend this product.

I purchased this product about 3 years ago and was somewhat happy with it for the first year or so, in spite of uneven water temperatures. Be aware the discharge water temperature will vary as the incoming water temperature or pressure changes. Then things began to fail one at a time after the warranty ran out. First a thermal cutout went bad. It took me two weeks to get one from the factory. (It's a specialty item only sold through Bosch....everything is) Finally the control board failed.
I'm tired of working on it and am going back to a standard, old fashioned and reliable hot water tank. To be honest, I really didn't notice much savings in electricity. This unit is just too unreliable to justify the high purchase price and the high installation costs. Invest in more insulation.
No, I do not recommend this product.

This tankless water heater is great. It was easy to install and provides enough water for my 2 bathroom home. It takes 3 double breakers so you have to make sure you have space in your breaker box for it.

The first problem that I encountered when "trying" to purchase this item was, that it was not available in a store. Normally when someone needs to buy a water heater it is an emergency and not being able to get one quickly was a hassle. I also recomend that you put an aproximate cost of additional materials needed, for me it was $160, fortunately I was able to install everything myself or the cost of installation could have been very large. So far the product usage has been questionable, adjustments have been made when using the shower, and sinks in my house. Overall I am not as pleased as I would like to have been with this product.
Yes, I recommend this product.

The only problem I have had is with my Water Company, and their issues with water pressure and repairing broken mains in our area. If you have water pressure issues, just set the temperature at a lower setting, and you should keep hot water.
