fantastic product saving lots of $$ already
I bought this product about last December but to supplement our oil fired boiler that we use for both heat and hot water useage. Here in the northeast most homes use oil for hotwater & heat and with the price of oil going through the roof I knew it was time to make a change.
I haven't extensively used the Bosch hot water heater until this spring when I shut down my oil burner for the season and now I rely totally on the Bosch system for all hot water use. I have a family of 3 children, my wife and myself and like all families with small kids we use tons of hot water. Every day the dishwasher and washing machine runs as well as 4 - 5 showers/tubs per day. I also bought a hot tub last year and my wife and I fill that at least twice a week. I had been using about 30 gallons of fuel oil per month in the summer months. Now I'm using 10 gallons of propane with my Bosch hot water heater! Hot water for showers and tubs is plentiful with a constant temp. The only downside of this hot water heater is that you don't have instant hot water on tap on the kitchen faucet. The heater doesn't kick in until 1/2 gallon of water has flowed through it so if all you want to do is wash a single glass or a dish it does take a few minutes for the water to get hot because of the lower flow rate of water going through a faucet tap. It makes more sense to leave your dishes until later or fill the dishwasher. I took the water saver thing off my kitchen faucet and I've found the water gets hotter faster.

DO NOT WASTE YOUR MONEY
Like other reviewers, I cannot stress enough...do not waste your money!!! We have this unit in our home. It worked great for the first 10 days, then no hot water. We had our gas company come out and had to pay them to sit in our house on hold for two hours with the Bosch's tech line. The technician had to leave because he had other service calls lined up for the day. Finally another technician was able to get through and Bosch asked questions until they found a good enough reason to deny our warranty, and then hung up on our gas company technician without even helping him to diagnose the problem. Since, I have sent numerous letters and emails to Bosch to complain and try to get some help fixing the water heater, and have received no replies. Our gas company called in their own "expert", so we then had to pay for two techs to work on the unit for about half a day, (not to mention our time lost at work), and the part they replaced cost about $450, plus labor. Now we are still getting error codes, we have to reset the heater everytime we want to shower or clean dishes, all of this on a unit that is only 10 months old!

Simply horrible.
This unit was a complete shambles of engineering. We purchased this for our home and instead of endless hot water ended up with no hot water for two weeks. It was due to condensation entering the unit and filling the gas valve inside the unit. This part incidentally costs $450 according to the plumber.
We did the right thing and contacted Bosch. Just so you know, be prepared to wait up to an hour plus to get through to someone. They sent out the new valve but didn't mention it would take a week to get here via Fedex ground. That would have been another week if we hadn't called them to overnight the part.
After haranguing tech support we had a plumber out to install the new valve. He managed to flood it as well probably due to inexperience. The lesson here is to make sure you use a Bosch recommended plumber. You'll find them at their website.
That done, Bosch sent out another valve by which time we just returned the unit to Lowe's. This was day 10 without hot water and enough was enough. They did offer to come out and repair the unit but having seen the plumber attempt to use a shop vac to suck out the water left the internal fan making groaning sounds. It just wasn't worth being repaired to 'like new' condition anymore.
As it turns out Tech support was accommodating enough to send out another Bosch certified plumber to check my installation of the new unit. It was another Bosch only because they are the only manufacturer of tankless units using 3" flues. The others use 4" and it would have cost another $400 to buy a new stainless steel flue system.
The new unit is sold as the 2400ES and seems to be a totally new model regardless of the badging. I'm quietly hopeful that it will redeem Bosch as a maker of quality appliances and tools.
If anyone is curious, it takes about 90mins of your day to boil up enough water on your stovetop to have enough water for your bath. Do that a few times and it gets old very fast.

Bosch worthless water heater
I would rate the unit at a negative 100.
One of the worst items I purchased. Water would fluctuate, be too hot to stand on the lowest settings. This was installed by professionals in a new house. I got several error codes. Finally had enough and called tech support. I was on the phone 2 hours the first time I called and that was on hold. Then I spent another hour playing games with the unit.
We spent over 10 hours talking to tech support over a month's period. I had to switch the unit on and off to get a bath. Tech support said the supplier told me the wrong unit to buy. Another tech support told me that that was wrong. I had to take off a lot of time to get the gas and plumbing installers to come back and check their work which was correct.
Finally I had enough and called the supplier. They worked with me to get me a credit. By the way that supplier no longer sells Bosch. Just give me your money instead of buy the Bosch unit. I can hand deliver consistent and dependable hot water better than Bosch. Oh yeah and you can get a straight answer from me without the long wait. Maybe the long wait shows that there are a lot of consumers that are having the same problems.
