Bosch AquaStar 125B NG Natural Gas Tankless Water Heater

Pros: Constant hot water.  Nice for taking really long showers or when company is over.
Cons: Just read the main review.

I've owned this model for about 5 years now, after buying it to replace a worn out 40 gallon tank.  Buyer beware...the $500 purchase price does not reflect the full price to get this unit up and running.  You can offset many of the costs if ...

Pros: hot water all the time
no tank so you have extra storage space
hangs on the wall
Cons:  maintennance is high-quality of plastic parts and glues are questionable-expensive parts

this unit is less than 4 years old - every year for 4 years  the carbon builds up so it has to be regularly cleaned in order so that it can  ignite -On a second visit the plumber decided to give me his steel cleaner and he showed me ...

Pros: Lowest cost in it's class. Hmmm it's the only one in it's class...
Cons: . If you like Russian autos, you'll love this.

Having installed tankless for decades my experience says use this for one fixture at a time and do your homework before purchasing any tankless. If you do not feel you can service this, do not purchase it. In hard water after a few years of no service, ...

Pros: I am sure that many people are very blessed by Televangelists and can afford them.
Cons: Televangilists should tell thier people as to why they are doing what they are doing.

Why do Evangelists have to go on television ?, are they really seeking after lost souls?, are they seeking those who are home bound ?, or are they seeking your money ? How many people do you think actually watch these shows with their Bibles in hand ...

Pros: Available at Lowes for a good price
Cons: Bosch said I should PAY a plumber to repair new heater!

My first Bosh water heater I bought from Lowes. I paid $150 to have it installed and we were not able to get it lit. After it would not light I called Bosch they wanted me to pay for a plumber to come out and repair it.I asked the operator if they would ...

Pros: Endless hot water.
Cons: Hard to control temperature + other high costs.

I have had this unit for about 6 years. I was happy once I go over the installation and it was all said and done. We did enjoy not running out of ho water but there are some huge trade offs. You will immediately notice that you cannot control the amount ...

Pros: tankless
Cons: 2 holes to the outside, quality is poor, size, breaks often.

had it for quite some time and would not buy it again. Too little for more than 1 bedroom house, breaks often, repairs and replacement parts are not so easy to find and expensive. when installing have to make 2 holes to the outside because it needs to ...

Pros: you have Pro & has done 5 installs/give him your info-he'll know.
Cons: No Pro you're taking chances. if it was your wifes suggestion, you might have chance.

My experience was in my own home. I could hardly wait for my water heater to go out... my 40gal. track-house unit lasted 18yrs. I purchased mine from home-depot, and bought the highest output rated unit they had. My problem was wife and Daughter.. It ...

Pros: Pros: Endless (but limited volume of) hot water, smaller than tank.
Cons: Cons: Temperature surges, expensive, maintenance

Note: I don’t own this hot water heater, but I own a similar one. The comments I make here apply to all tankless heaters, regardless of brand. These are things you should consider before making a purchase. They are also things you won’t hear from the ...

Pros: Space and energy savings in the long run.
Cons: Installation hard, won't notice any savings right away, can't to many things at once.

When I moved into my house over a year ago the first thing that I had to do was replace all of the plumbing. Then I noticed that I needed a new water heater. We originally had a 40 gallon heater. I really would like to have a 50 gallon one. I shopped ...

Pros: It saves space. It's cheaper than any other tankless heaters I've seen. It's energy efficient.
Cons: Difficult installation. Temperature varies. Faucet must be fully on to operate (no hot water trickle).

The following review was my initial opinion of the Aquastar 125B. I have updated the title and pros/cons to better suit my current opinion but I'll leave the review alone because I think it helps illustrate how this heater can take some dialing in and ...

Pros: Good for the environment, save energy, no standby losses, compact.
Cons: Often don't meet high water demands of North Americans, need maintenance plans factored in.

Tankless, gas-fired, instantaneous water heaters have been trying to break into the North American markets since the late 1970's and early 1980's. It therefore isn't "new" technology, as countries like England, Germany, and Japan have all been ...

Pros: none
Cons: EVERYTHING! wastes water, won't stay lit, unethical tech support behavior

Since the purchase of this faulty water heater, it has never worked right and has been a persistent problem. It can shut off 3 times during a single shower, or the pilot light may extinguish when not even in use. For years I have been on the phone ...

Pros: Energy savings, space savings, continuous hot water on demand, long life, earthquake safe.
Cons: I had one service call during the last eight years.

I have used a Bosch Aquastar 125 in my home serving a family of four for more than 8 years. This water heater works like a spa water heater by heating water as it senses water passing through a heating chamber. It is "on" only while the water is ...

Pros: good for cottages, one person house holds, for spatially challenged areas.
Cons: Horrible: Output GPM, COST of Unit, installation, maintenance.

I've installed one in my home also. At first I was satisfied, but now I have grown annoyed with the heater. No one else in the household can use the hot water while you’re in the shower, or else you will get doused with cold water. Also, it takes ...
