Answer: 
We do not have published BTU ratings on our electric only water heaters. One can conduct a quick internet search to find how to calculate BTUs from watts. However, as we do not publish it - we cannot vouch for the results as it applies to this unit.

Can I hook it up in line to the current hot water line so that I will use the existing faucet?

Answer: 
The unit is designed for cold water input only. One of the concerns is that the unit heats whatever temperature the incoming water is by the same amount regardless of the incoming temperature. Therefore water that comes into the unit already hot, will likely exit the unit too hot for safe use.

Answer: 
Can't say for sure. However, this unit produces a flow of 0.75 GPM. If you get a one or two gallon bucket (and a water resistant watch) and place the container under your showerhead and then run the pressure as you normally would and it does not exceed .75 gallons in a minute, you should be fine in northern Alabama. War Eagle!

Rated 3.5 out of 5 by 31 reviewers.
Rated 4.0 out of 5.0 by Pretty good solution to cold water at sink problem. With restricted electricity supply. I did not install this personally, but a plumber did as part of a remodel. That said, i don't believe this is hard to install, even i might do it and i hate plumbing! This was installed on a cold water line (in Texas) during February for a kitchen faucet. It has been cold, ie. the water is going to be cold too, and the water has been the right temperature for washing dishes. No need to cool the water with the cold tap, and in fact this *won't work* because if you turn on the cold tap in a "mixer" arrangement as we have the back pressure from the cold tap swamps the hot pressure and the water heater shuts down. The flow is perfectly adequate for a smaller sink, maybe a bit low for the large sink i have. I would have bought a higher flow model but was restricted to a 30amp model as a larger one would have necessitated a $500 charge to an electrician to run a new wire (not economic sense for a $150 water heater). Was considering attaching to the hot water line (the distance from the tank is so great the water was cold when it *eventually* got there) but this is expressly forbidden in the instructions. Makes sense as there is no heater cut-off when the incoming water gets too hot (why? The higher rate models do, is it because they cost more?). If i ran a sink-full of water then the hot water from my tank would have reached the heater and caused a problem. Best to avoid that. Anyway, i am happy with the product. We've had it running a month and once we figured out about not running the cold tap at the same time we haven't had any problems with it and our dishes are clean. March 15, 2016
Rated 5.0 out of 5.0 by Tankless Electric Water Heater The water heater is easy to hook up to plumbing supply lines. You will need to have the correct size wiring and plug for the 240 volt power supply. Works fine for a single sink that we use at our camp. August 24, 2015
Rated 4.0 out of 5.0 by Good point of use water heater Needed to have hot water in the tack room of my horse barn. For years there was a 30 gal electric hot water tank. When the tank started to leak I decided to try a tank less heater. This one looked like it would do the trick. The 7.2 kw 240 Volt Point-of-Use Tank less Electric Water Heater works well. The installation was easy, and quick. You can see the switch working as the water is turned on, (if you are curious and check it with the cover off.) I was concerned about low flow from my well but it still worked well. Hot water in 10 seconds. Probably will pay for itself in saved electric. Or I would have been saving for years if I did this sooner. July 9, 2013
Rated 2.0 out of 5.0 by Does what it's supposed to do... Installation was a breeze. The unit is fairly compact and can be located just about anywhere. It allows for horizontal or vertical mounting. This was purchased to supply hot water to 2 small back-to-back sinks. The hot water it produces is barely hot. It's good enough for its intended use, but you can't expect it to supply sufficient hot water to a shower, washing machine or dishwasher. You'll need to look at higher output models for those types of applications. Plus, if both sinks are turned on at once, flow is cut in half. Knowing what I know now, I would not recommend this unit, as it just does not produce enough hot water. May 29, 2012
Rated 1.0 out of 5.0 by Junk DO NOT BUY THIS PRODUCT. After professional installation, we had to reset the internal circuit breaker after every few uses. Then it would just stop working altogether. Then start working again. When it did work the temperature was totally inconsistent no matter how much we varied the temperature setting and flow rates. We called Bosh and were told to contact their local service representative. He came out but told us he only worked on gas heaters. Bosh's warranty required us to pay for an electrician to come out. But now, on top of everything else, the unit leaks. JUNK! Don't waste your money! May 21, 2014
Rated 2.0 out of 5.0 by Restricted Put this in for a sink in my shop, there is 100psi going in the heater and about 1psi coming out. It definitely makes the water hot but there is no pressure what so ever. I thought it was clogged somehow but it is actually restricted internally to a 1/8". If it had more flow it would be great as it heats the amount of water coming out great. Enough so that you could have more flow and it would probably still be scolding hot. Disappointed that I couldn't adjust to get more pressure out. Took it back and am looking for a different heater now. It is the ae7.2 that I had April 23, 2013
Rated 2.0 out of 5.0 by Not worth the effort to install This unit had to have a heavier breaker installed. You should use the defuser that they supply because it slows the water down and gives the unit a chance to WARM UP. That's right WARM UP. ITS NOT HOT! If you have to fill a pot with warm water and you have the defuser installed please be prepared to WAIT. it's slow. In review, not hot water, the flow is slow, and it's a waste of time to install. Buy a small hot water heater and run a propane line to it and hook it to a BBQ tank. Don't buy this thing September 8, 2015
Rated 4.0 out of 5.0 by Very useful device Wasn't the easiest to install. Had to get an electrician. Needed to run a dedicated line. Expensive. Had to get a plumber. Expensive. Awkward to use one unit for 2 sinks with one faucet and 2 handles each. Chose to connect to house hot water. Doesn't work well if flow restrictors used. Have to balance hot and cold flow, otherwise cold flow dominates. Need trial-and-error method to get flows right. October 13, 2015
