Review on 7.2 KW Bosch Electric Tankless Water Heater - Instant Hot Water, Easy Installation - US7 by Justin Garcia

Updated review: Well that did no take long. I updated my review from 5 to 3. It does what it has to do. BUT there isn't any temp adjustment POT on some models. The US7 model can only adjust the temp with flow control of the service valves. I only had one cold water valve - so I had to split it. When I run cold and hot at same time - you think you would get warm water - but since there isn't enough GPM flow to enable the flow switch - the heater shuts off. So I need to switch back and forth between hot and cold - not a deal breaker - but not what I was expecting. I was told you can run this as 110v to make it less hot as there is a voltage selector switch - but I did not see this in my model. I called customer support and they helped a bit - but did not seem that enthusiastic. Meh. I could saved time, money and energy by buying a lesser model such as US3 - but you don't know what you don't know. Hope this review helps you avoid some of the same mistakes I made.1st review: This did the job as expected. I had to wire a dedicated 220V 30A circuit using 10AWG - which is not the easiest to work with - but necessary for a device that draw that much power. I'm not sure what the negative reviews are about - but my assumption is that they may have not been wired correctly. At this point it’s a water heater it has one job. of course, I’ll update the review as needed. I see people posting that it died after a few months. One thing that is also needed, is that you do need a certain flow rate so the flow switch is activated. Nice and hot water on demand.
