Stiebel Eltron 202151 DHX 15-2 Plus 240V Tankless Electric Water Heater - 14,400W, Instant Hot Water for Kitchen, Bathroom & RV - Energy Efficient On-Demand Heating Solution

For a long time I have been an evangelist of sorts for what I call POUET - Point Of Use Electric Tankless. I have done it in three house. Basically, it means having an electric tankless at virtually every water source. That's between 4-6 units per house. I'm a believer in POUET's ability to save water and power. PIus I love-love not waiting for hot water. I published an article once on Green Building Advisor. Phew! Be ready for a firestorm anytime you speak out on anthing different.I have bought...I dunno... maybe 2 dozen different units in my quest. This one is by far and away the best. It works great - but most properly sized units do that. Besides the great graphical interface, what is amazing is that this unit actually controls (slows) water flow to achieve set temperature. Amazing! Finally!I have a very unusual floating house with long exposed water line. It's winter right now and the incoming water can be near freezing. I set the temp to 102 for a shower, then watch the screen as the unit slows the flow down and down and down, from a start of 3.5 GPM down to .9 GPM (last night). This is something I used to have to do manually and tediously. Truly amazing!There is one thing that I wish it did better: As I said, I have a long, exposed water line. In the summertime, the incoming water can be quite hot. This unit has a unique feature in that it has the ability to tell you that the incoming water is hotter than the set temperure. In other words, it has a inlet temp sensor, but it only comes on in "over temp" conditions. Why not tell the inlet temp all the time? Inlet temp is a useful piece of info for tankless. I hope that made sense, but it may be TMI.
