Answer: 
Yes, but the AE 12 needs a 220 power source and will provide much more hot water than the AE 9.5.

Answer: 
MORE THAN ENOUGH! If you read the specs, it is adequate for a 4,000 sq ft house. It might be too much for a hot tub. As I said in my original write up, it does heat up enough to melt the plastic casing. You actually need to go to a smaller unit.

Answer: 
First, your dishwasher should have a heating element. This is a common component in dishwashers of today and going back as far as I can recall. If it does, you most likely do not need to use hot water for the incoming line to the dishwasher (check your model's instructions before relying on this answer, but mine works fine with only a cold connection).

First, your dishwasher should have a heating element. This is a common component in dishwashers of today and going back as far as I can recall. If it does, you most likely do not need to use hot water for the incoming line to the dishwasher (check your model's instructions before relying on this answer, but mine works fine with only a cold connection). Even if your unit requires/recommends a hot water connection, ask yourself what typically happens if you use a timer on the washer. When the unit activates it is pulling in cold water from the line until the hot water from the tank finally shows up. And there is a good chance the washer has all the water it needs before the hot water shows up. When making your decision, know that this item requires a 50A service with 240v and include any associated cost in your decision. So given that you do decide to use this for the stated purpose, this is a tankless water heater and will provide a never ending supply of hot water. It supplies at 0.6 gal. p/minute, so check your washer's requirements - but that should do the trick in most cases. However, know that your dishwasher will only use a finite amount of water. Once your dishwasher starts, it most likely uses the same water during the wash cycle and then will use a fresh supply of water for the rinse cycle (again, check your model's specs). All this said, and you need/want a hot water source for your dishwasher, you can come out better on total cost with a point of use mini-tank water heater. These are available from Bosch and THD in tank sizes from 2.5 gal., 4 gal and 7 gal. (models ES2.5, ES4, and ES8 - all available through THD, search Bosch with the model number). Check the space requirements (size) for each model. The tankless point of use model you are asking about does take up very little space vs. the mini-tanks. However, the mini-tanks only require 12A/120v service (this should be much less expensive and less involved than the 50A/240v option). And the mini-tanks can use a standard three prong plug (ES2.5 and ES4 come with it installed - hard wire is still an install option). If going with the mini-tank option, check your dishwasher's manual to ensure the tank's capacity is adequate for your machine's needs. I can't envision needing more than 4 gal., but I don't know your washer. Read Less

In a shower using about 1.5 gpm, it works perfectly. However, if your water pressure cycles too often between hi and low pressure, you may notice periods of chill water temp or very hot temps. I am now using my own storage and pressure system, and it works perfectly with my heater whereas before the system pressure changed too much and too often, causing overly hot-or-cold shower spray.

Rated 4.1 out of 5 by 42 reviewers.
Rated 2.0 out of 5.0 by disappointed Wiring fried after 3 months use, second unit wouldn't stop heating the water even when the water was not running. Finally 3rd unit seems to be working fine. 3months in use... June 10, 2015
Rated 1.0 out of 5.0 by Not exactly the deal it looked like. Within one month of installation, the board fried because of a direct short in one of the elements. Called the maker and they agreed to replace it after seeing pictures of the fried board. Paid overnight shipping so I wouldn't have to wait for up to two weeks and installed the replacement the next day. Almost six months to the day, the replacement started only giving out a luke warm water supply. Ran some checks and found that two of the elements had no resistance. The elements appear to be the weak point of these heaters. January 31, 2015
Rated 4.0 out of 5.0 by OK one bathroom water heater This water heater works pretty good for one bathroom in the south (East Texas) with a low flow shower head. It takes a little time to get used to how to adjust the temperature at the faucet. The installation of the new wiring was difficult. But, the small size has given us a whole new closet that the old water heater was stored in. Also, since we use this just for our guest bath, we no longer have to flip the breaker when people visit to turn on and off the heater. All and all, a good product especially considering the price. When our main water heater breaks, we plan to replace it with the "whole house" version of this water heater. September 26, 2009
Rated 5.0 out of 5.0 by LOVE IT!!! I bought this unit for a whole house water heater... My house uses one wet wall so I bought this unit to replace a leaking water tank... easy to instal and it works great!!! endless hot showers are very nice... I have already recommended this product to four others including my dad! I'm not disappointed with this as it does exactly what it says it can do, I do recommend that you read the product info before you buy and buy the right size for what you need... as for my little home, (three bedroom one bath 1400 square feet), the 12KW unit is perfect! I'm now building a towel closet in the space the old hot water tank use to occupy... February 5, 2011
Rated 4.0 out of 5.0 by Could be better. This one was purchased to replace the same exact model that malfunctioned. I have been using it in my grooming salon and it just has to make hot water for one bathtub. Which it does a good job at. I don't know what caused the old unit to malfunction whether it was the age of the unit (3 years old) or if it was from overuse. I only use it to bathe on average 6 dogs a day. It does get hot fast which is nice but, now I am super aware of it due to the last one almost catching on fire. I would recommend it if you are using it for a sink for sure but, anything more might be pushing the unit. October 23, 2012
Rated 5.0 out of 5.0 by Product works as stated It has been several months since my purchase of the PowerStar point of use water heater. I was apprehensive since I was going to use it to service the Kitchen sink, dishwasher, washer and half bath sink. So far I have been pleasantly surprised. It provides adequate hot water to all areas at the medium setting. FYI we only run the dishwasher once/twice a week and one or two loads of laundry a night. Can't speaker to cost savings yet because I haven't had the time to do the evaluation. however it did give back some much needed closet space in the laundry area. So far extremely pleased! September 17, 2012
Rated 3.0 out of 5.0 by Provides emergency hot water use. Bought this product as a stopgap measure when severe flooding ruined our furnace and left us without hot water. We installed it near our upstairs bathroom sink, but running a 240V, 6/2 cable wasn't all that easy (except for an expert, of course). It provides hot water at our bathroom sink, but for showers, the hot water must be turned all the way on with no cold water to get even a lukewarm shower, even with no one drawing hot water at the sink simultaneously. At least we can take "warm" showers, but the cost doesn't seem to be equal to this heater's productivity level. Glad I didn't purchase the whole-house electric tankless water heater because the productivity just doesn't seem to be there. October 11, 2011
Rated 5.0 out of 5.0 by GREAT if you understand how it works These save a LOT of $ only heat when needed. Should be VERY close to where used. Thermostat helps to give regulated temp after a few sec to minute. First cold, very hot then averages out. We are in FL, coldest H20 is about 69 to 70 degrees. Used for Shower and sink. Installed aprox Feb 2011. Have had other units from this co. They stand behind the warranty and have exelent Tech help. The warranty used to be 5yrs, now it is 2 & 5 IE parts 2 and heater unit 5. Thier website says 1 & 5yrs. so prob changing. The 2/5 was indicated by Home depot. February 19, 2011
