Review by F. PATCH:

My wife reminded me that our children and grandchildren were due to visit our cottage in one week, but not hot water. I placed my order on line and it was delivered in 3 days. Hot water at the cottage in 4 days. Wow it only took me 15 minutes to install. Then hot showers for all on the weekend. Great product.Bosch PowerStar 1.5 GPM Point-Of-Use Indoor Tankless Electric Water Heater #AE9.5

Review by Flashlight fan:

This heater works as advertised! The adjustments for temperature and the 220v hookup should be done by someone comfortable with these tasks – the instructions are not as clear as they could be. The indicator light is very helpful it adjusting the flow as it indicates when the unit is on (there is a click also).

Review by M. Esaili:

This product is perfect for homes where the space is an issue or for locations distant from heating source.

The first heater we received and installed was mulfunctioning. After discussing the troubleshooting with BOSH, Amazon the same day we contacted them sent us new replacement. Returning the first heater could be easier. Thank you Amazon.com!

My electric panel was just some year new, we did not have to provide any additional works besides wiring the heater. I saved all closet space(where I had located 30gal. el water heater) for other use. Heater is very small, it would easily fit under the sink. Temperature of hot water can be adjusted to your needs. 2 gallons of hot water per minute are good enough. According to professional installer, the heater is so simple device, that it should not have any additional problems.

I am very happy with the product and am starting considering this type of hot water heater for whole house, no matter price for electrical works.

Where the space is an issue, this product is one of great solutions.

I am highly recomanding this heater.

Review by Steven Ebstein:

On InSinkErator’s (ISE) recommendation, we bought this tank and filter to replace our 5 year old unit that still heated, but whose output was undrinkable – a funny taste due to corrosion of the tank (?). While the replacement tank and filter work fine, it was quite a job to install for this amateur plumber, due to ISE not providing good information or the right fittings. Our old unit used 1/4″ copper from the faucet to the supply and to the tank. The new unit uses 3/8″ polyethylene tubing. ISE should have known this, since we provided the serial number of the old unit when we called and had this unit recommended, hence only 3 stars. Gory details follow for anyone in the same situation.

The new tank is wider than the old one. So, I had to move the mounting bracket so the new tank did not interfere with the supply valve. When I called to explain the tubing mismatch, ISE sent an adapter for the line from the faucet to the tank (1/4″ compression to quick-disconnect). However, the 3/8″ to 1/4″ Y adapter from the filter leaked when I tried it with 1/4″ copper tubing. I ended up getting 2 1/4″ to 3/8″ compression adapters from Home Depot, which did fine with the copper 1/4″ tubing and the plastic 3/8″ tubing. Two are needed since the filter goes in between the supply and the faucet. Do-it-yourselfers will also need a compact tubing cutter and some extra 1/4″ compression nuts and ferrules.

Review by S. Proper:

Please call Insinkerator and verify the warranty policy before purchasing and installing these types of products.

My poor rating is entirely related to the warranty service I attempted to obtain after my SST hot water dispenser quit working after 8 months of operation. During my contact with Insinkerator via the 1-800 number it was revealed that I must have have a copy of my receipt “for professional product installation.”

Okay, what kind of a game is this? I do not have a receipt for installation, because I installed it myself using the instructions that were provided in the manual. The manual never specified professional installation required for warranty coverage.

On my further insistence on unit return and replacement, the customer service rep continued “We do not have a repair facility or shipping address. An Insinkerator selected plumber must be dispatched to your location. “You should be aware that you will be liable for the service call and the full unit replacement costs if it is determined the installation was not correct.”

Okay, this is rubbish. The unit is a small, plastic, foam and very thin steel tank weighing less than a two pounds. It has two internal components, a 98 cent thermostat and heater element. The water flow is fine, so the thermostat or element quit. Why should a plumber be required to fix an ELECTRICAL PROBLEM?

At the time of purchase I was not aware of other alternatives. I now see that a simple electric hot water pitcher or heat-on-use hot water heater would have been better alternatives and have provided better warranty support.

My advice, keep looking.

Review by Brent D. Healy:

This is for Jack Stecker. maybe you shouldn’t be crushing all those pills buddy, I think it’s negatively impacting your brain. This water heater is not intended to replace a tank water heater, it is not for your whole house.

If it is tripping your breaker, it is because you did not wire it correctly, or are using the wrong size breaker. The wire sizes that Bosch says to use are NOT intended as a guideline, they are the size that the unit needs. You are probably very lucky you didn’t burn down your house. Next time follow the instructions, ALL of the instructions, and take the pills AFTER you are done with the wiring. I have two Bosch tankless water heaters, and they are awesome, but they need to be installed correctly. And yes, they do draw more electricity when they are on than a conventional tank water heater, it’s just that they are only on when you need hot water. that draw is why you need to follow the directives about wire size. If it says 8ga wire, you CANNOT use 10ga.

Also, the size requirement for your house service needs to adhered to as well, if is says minimum 200 amp service, you cannot use it with a 150 amp service, you could burn your house down.

My advice, buy the 220v unit and have an electrician install it for you.

Review by Fixup:

I don’t know why few stores carry this and few people are aware of this great product, including those sales persons in home improvement stores. It gives instant warm water to all the rooms in your house, it saves 10,000 gallons water a year (really, I measured and calculated) and it is so easy to install.

Doubt about if it really works? Try this: go to the farthest faucet in your house and open the hot water. Once the water becomes hot, close it, but not fully, leaving a very small stream. Now go to other faucets and open hot water, you bet, instant hot water! It’ll keep this way as long as you keep that small stream flowing.

The problem is that small stream goes wasted. How about recycle it into the hot water heater? Sure, but how? The hot and cold water lines have the same pressure, therefore water cannot go from the hot line into the cold line. What if I add a pump into the hot line? Exactly, that’s what this Watts product does. Problem solved.

For a practical and fine product, Watts also add a temperature sensor, so the recirculation only happens when the hot line becomes not so warm. This, plus the stream is really small, adds very small extra energy cost to the heater.

The pump is very small, only 25 watts, using less electricity than a lighting bulb. There is also a 24-hr timer (in 15-minutes increments), allowing you to shut the entire system off during the periods when you do not use warm water, such as sleep and work times. This reduces even further the already very small added energy cost. BTW, the pump is thoroughly quiet, no audible noise at all.

An alternative product is the Laing Autocirc. It is a single piece can all be installed under a sink, could be a better choice for some people. The downside is you need (to add) a AC socket there to power the pump. The upside is the pump does not operate continuously like the Watts; it is controlled by the temperature sensor and thus turns on only when water becomes not so warm. Might save some more Watts than the Watts. Both are available in Home Depot stores.

I cannot think of a single reason not to install such a system into any house. Instant hot water without any side effect or significantly added extra energy cost and saving tons of water each and every year. I wish I have done this long ago and this product will be more widely spread.

PS, a tip: before you start the installation, go to Rite Aid or alike store and buy a pack of Hose Washers for

Sunpentown Hot-Water Dispensing Pot – 4 L Reviews

Review by Getting rained on:

I purchased this unit for my wife for Christmas of 2006 (started using in January 2007). As a frequent tea drinker, she loved the convenience of having hot water available on demand. Last week the unit started reboiling when it wasn’t supposed to and no longer stays on the “keep warm” function but instead keeps boiling as though we’d just filled it with cooler water. It also dispenses in spurts and gurgles, as though there’s air trapped in the line. The reslult is hot water spattering in every direction. Basically, it’s a hazard. Thank God we didn’t leave it plugged in while we were away.

I recommend this product for anyone who’s interested in having it work for 12-15 months before it fails. Those who desire unreliable appliances that could be fire traps might also be interested.

Review by P. Noland:

We bought the SP-4000 in the last week of 2005. It stoped working in the middle of March. I called the number on the back of the pot for warranty service and got an answering machine. They have not returned my calls. I guess they expect me to throw it in the trash. It was nice to have until it stopped working.

.99 (e.g. Plumb Craft by Waxman, 74-114, 6 pieces). After you unplugged the hose from the heater and before you plug it to the pump, you should remove the old washer and use 1 or, if the old one is very thick, 2 of the new washers (I had to use 2). The old washer was usually hardened by the high temperature; if you don’t replace it, it will leak water. The menu does not mention this, so I learned this the hard way. BTW, hey Watts: for a 0 product, such washers should have been included.

Review by Raybert:

I installed one of these Sunday since I was tired of running the shower 1 1/2 minutes to get hot water up to my 3rd floor bathroom. It does work, but there are issues.

First, the sensor valve setpoint is fairly low, I am guessing about 90-95. So the recirc stops when it reaches that temp. The really hot water is still back down the pipe a good ways. I suspect they do this to avoid scalding but in practice this make scalding more likely. That is if you get in the shower immediately because the water will keep getting hotter for awhile requiring that you adjust the faucet… or get scalded. So I still need to run the water awhile to get it hot.

Second, there is a certain amount of natural circulation that occurs even with the recirc pump off. It seems to happen more when the hot water heater is active like when running the laundry or whatever. Just creating a high temp diferential in the HW heater provides enough head to move water a bit. It isn’t a prolem in the winter but in the summer the additional heat loss from the pipes will add to the A/C bills. I have a workaround planned to fix this.

Also, the timer is very lame. Better just to turn the recirc pump “on” then control it through an X10 or Insteon timer and appliance module. Then the typical usage periods can be set to automatic and the recirc pump can be turned on and off manually with a keypad or remote for usages outside the programmed times.

Not perfect, but a worthwhile add on.
