Nice and quiet. But without a heater, you must open the door when washing cycle finishes and there is steam coming out, so be careful. It requires Finish Jet-Dry for drying - so we wash every glass again before drinking out of it.

We purchased a Bosch Powerstar tankless water heater with a 10-year warranty in October of 2008 from Home Depot. At the time, the price on the water heater was $800. In September of 2012, it stopped working so I called Bosch. The first rep told me I needed a licensed person to come out and look at it before I could claim warranty on the unit. This was on September 28th. Okay, not a problem, right? Wrong! First off, they do not have technicians to send to look at their products so I had to call a plumber and I couldnt find one that could come that day. On October 2nd, the plumber shows up and after extensive arguing between Bosch and the plumber because he was told to disassemble the unit, take photographs of the inside, and send them to the Bosch tech. But first, they would have to send us the new O-rings before the unit could be disassembled, so $80 to the plumber and he left. The O-rings finally arrived on October 10th so another call to the plumber. He came out on the 12th. After 4 hours of this crap and $320, they decided to warranty the unit and said they would ship out a new one. Well, today is October 22nd and I still do not have my new water heater! I called Bosch this morning and they didnt send it out until the 18th. So now, after 25 days of no hot water, I have decided I will never buy another Bosch product in my lifetime and I hope you wont either! Very bad customer service.

My father purchased a Bosch tankless water heater about 18 months ago. He had a professional plumber install the tank to the specifications that the factory mandates. The unit never did work properly. After hours on the phone with tech support listening to every reason in the book why it wasn't "their" fault , and hundreds if not thousands of dollars spent on a plumber they still will not honor their warranty and replace the unit. The problem with the unit is that whenever you turn on the cold water to make the water warm instead of scalding, the heater shuts off completely leaving you with ice cold water. The factory techs tell us that there is not enough water coming into the unit. Ok easy fix right "just tell us how much water is required". O wait the "tech" isn't allowed to suggest anything like that. My father is so frustrated he wants to take the unit outside and shoot it with a rifle. If there is a class action we want in!!!!!!

I have a bunch of these in a commercial strip mall I own. They work very well for bathroom sinks and are easy to mount and set up. I have had one failure with this brand and that was after 8 yrs of use. This wouldnt supply a shower but is great for light use and you dont have to find space for a tank or worry about it always heating water and wasting electricity. These units only energize when the hot water is being used.

Purchased new Bosch tankless water heater. Nothing but problems. Turn on hot water and the moment I open cold water tap the heater turns off. Have spoken with plumbers Re this problem and they all say this is an inherent problem with these heaters. You can only open hot water tap. The moment you want to mix hot with cold the heater turns off. Absolutely junk waste of good money. Tore it off wall and purchased a reliable hot water heater conventional. Also Bosch products in general are total crap. Will not purchase and will not recommend. Obviously not made in America.

Super please with this purchase. Been using it 6 months now, supplies our bathroom shower and kitchen sink. We take a shower with it no problem, however if my wife turns on kitchen sink hot water, temp drops substantially in the shower. This small units can really only handle one demand at a time... which is fine for us. We live simple, 600 sqft house. Here's the only tricky thing about it, and it's just a limitation of the size of the unit: the bath-tub water flow is too much to heat the water sufficiently, so I had to manually close my hot water valve to the bathtub about half way. This slows the flow of the water through the water heating unit and allows it to get hot enough to be good for bath temperature. So the bath tub takes a while to fill. Not a big deal for us. I did a lot of reading on different units and this one seemed to have the best reviews. Even if this unit died in a couple years, I would buy it again and re-install a new one.

Tankless water heaters save you a lot in energy bills, fit into small spaces, and are built to last longer. This makes them advantageous than the traditional water heaters. Bosch tankless water heaters are some of the best in the industry, offering premium features like better performance, better durability, and Wi-Fi connectivity, too.

I have been dealing with a non-working tankless water heater for about a week, and Bosch customer service keeps telling me from pictures I sent that the install is incorrect. I have had many technicians come into my home and verify the setup and that Bosch, a reputable company, should accommodate us. Its been under 5 years since we have used these units and with not having hot water for almost a week and the countless phone calls to Bosch and emails with pictures, I am resorting to going to the Better Business Bureau. We had the town of Clifton verify everything before they issued us a Certificate of Occupancy. This CO would not be issued if a potential threat was posed due to incorrect installation. We also called Clifton City Hall, who said install was done according to city code. Of two, only one tankless water heater works. I will mention all over social media how Bosch treated this situation and my overall experience. We had to pay multiple amounts to the plumbers who visited our home, who ended up telling us this is something Bosch should be handling for us. Where is Bosch when this customer needs them to help? The 15 year warranty is mighty easy to void isnt it. Also, if Bosch is so confident that the install is incorrect, why doesnt Bosch come here and take a look themselves? Id appreciate a response as this is getting extremely frustrating.

Bosch hot water heater GHW 1600 H - After my hot water heater stopped working, I called support system. I received an absolutely no help from your service. The lady was only concerned about if I was certified to work on my own personal equipment that I bought from your company. I am very knowledgeable about the electrical and mechanical equipment; I am a machinist over 40 some years. She advised me that I had to have a service tech call her to get the information off of her. You cant even find a park to replace the equipment that I have. What piss poor support. I will never buy another product from Bosch.

Right out of the box, our brand new Bosch tankless water heater (2700 NG model) did not work. Our plumber called their customer service. The person he spoke with, and subsequently my husband spoke to as well, was extremely rude. He told us that we would have to order a new one (it would take four days to deliver) and that we would have to pay the plumber to reinstall the new one as well as pay for shipping on the new unit. Who has that type of customer service? It was brand new and just out of the box and it is defective. The hardware store where we purchased it told us it was an issue that we had to take up with Bosch. Talk about being between a rock and a hard place! After hours on the phone with both Bosch and the hardware store, Bosch agreed to send us a new tankless heater and the hardware store agreed to pick up the overnight shipping cost. We are still out the cost of having the new tank installed. I would never purchase anything that bears the Bosch name on it. And yes, I did my research about tankless water heaters. This will be the first of many websites that I will tell the world about the poor customer service by Bosch. Do yourself a favor and purchase any other tankless besides Bosch!

I have a Bosch on demand hot water heater under warranty. Service was promised everyday for the last 4 days. The service desk promised the technician would call me as well every day. I have waited in my house for 4 days for him. So far, no tech, no call and the number they gave me to directly contact him does not function.Many people ask me about the heater and if it is better than a tank heater. I will never recommend Bosch to anyone after this. The service is non-existent and insulting. Buy a Rinnai.

Bosch tankless water heaters, powered by natural or propane gas, are the most popular type for water heating, but the company also offers types and models that are very attractive to buy too; small and tankless electric models, point-of-use tank-type and gas boilers.
