Best 120V tankless you can buy in my opinion
In late 2010 I bought and installed a PowerStar 120V tankless water heater to replace an old 10-gallon tank water heater that provides hot water for a kitchen sink. I was limited in options due to having a single-pole 30 Amp breaker feeding the circuit with #10 AWG wire. Be aware before buying that you must have a single-pole 30 Amp breaker powering your circuit. In most cases where you are replacing a tank style heater, you will likely have to upgrade your breaker to 30 Amp rated and your wire to #10 AWG (most 120V circuits are #12 or 14 AWG on a 20 Amp breaker). The PowerStar, manufactured by Bosch, is by comparison much more cheaply made - I base this on the quality of parts viewable when the unit cover is removed. The water would only get lukewarm, maybe 100 to 105 degrees Fahrenheit, which is not very hot at all. The unit would also intermittently fail to heat the water at all. Not very impressive. At the time, it was the only 120V tankless water heater available...

Good engineering, Disappointing Results
Had high expectations that this nice looking German engineered device would solve demand for instant hot water at a single sink. Not exactly "instant". It takes a while for the water to even get warm. The problem is the water needs to flow slowly in order to benefit from the electrical heater. Naturally that means a very low flow output. A small tank device would be better...but alas, is much more expensive to run in order to keep the water hot 24 hours a day. Also don't forget...This requires a new 30amp electrical circuit and water by-pass shut-off valves to be installed. Not for the handyman-challenged.


Stiebel
The Stiebel heater worked just a I expected. It was quite easy to setup and it heats the water adequately. Great product.
