Update: if power goes out, it stays off. So best to install where you can easily access the front panel to turn it on again. Mounting was a breeze with included template and brackets. My water is around 85 F (30 C) coming in at 1.25 gpm, so there was no reduction in flow to kitchen sink at 109 F (42 C) setting. So far (after a day of use) there have been no snafus or shut-downs. The manual warns that much hotter water will come out at first with start/stop/start, because the water next to the coils will take up residual heat at the stop, so be careful (if you think about it, the situation is unavoidable by the very nature of electric boilers) and get in the habit of running the hot for a bit before plunging in with your unprotected hands (another reason I set it at 109). The biggest problem was running a 240 volt line to the sink, so this unit is best for new build or sites where you have an easy wire pathway to your electrical panel. Also, the manual advises to avoid mounting in areas where water can possibly drip down onto it, so that pretty much excludes under-sink installations, where I imagine most would want to install it for access to the water supply lines (as shown in two of their product images), even though the text recommends installing 'a few feet away." I would have hoped the manufacturer would have engineered a water resistant housing just for this situation. Seller also follows up the sale with an email reminding of electrical requirements. I've not needed tech support. So far, so good! And happy to instant hot water at the kitchen sink (the farthest point in my house from my hot water heater).

This was bought in a pinch to replace our water heater that started leaking, some comments mentioned it doesn't heat enough on colder days. In my case, south Texas doesn't have very cold winters, and when we do, they don't last too long. But this water heater has kept up so well, I haven't had the need to install a larger one, and it's been more than a year since I installed it.

Dosest work , I am praying bought a limon the first time because the plumber& electrin getting the set up for the unit took much longer than the 1 MONTH WARRNTY PERIOD ON UNIT I did purchase another ONLY BECAUSE AT THIS POINT have 2000. Invested in plumbing & wiring for a unit exactly like this 1 it is a shame that factories which I do understand do have factory defects occasionally make consumers pay for insurance to cover the workers errors OR JUST COVER THE WORKERS mistakes out our pocket books. Why should I the consumer have to pay insurance to cover YOUR FACTORY to train tempory employees 200.00 is a drop in the bucket to some people but to others it is 1/4 of there monthly income

I love my water heater. I am in the Midwest USA and inlet temperatures are still very cold in May. It takes less than 10 seconds to receive unlimited hot water. After I installed the unit I needed to contact the company directly for troubleshooting my unit. They are in a different time zone so there was a slight delay in initial email response but when I was connected with my rep they followed through with everything extremely fast and with urgency. I am ultimately very happy with my unit and the outstanding real person customer service I received. I would absolutely recommend this brand water heater.
