120V Electric Tankless Water Heater | MIZUDO 3.5kW Instant Hot Water for Sinks | White

Upon opening the box (which was packaged well and quickly and safely), I immediately thought “there’s no way that this thing is going to output enough hot water to supply all of our Master Bedroom’s Bathroom needs (2 sinks and a huge walk-in shower), along with a Kitchenette that has another sink.” Well, I was wrong. I have no idea how they engineer these little things to be such monsters at continuously outputting hot water, but it’s impressive. I have a 6,000 sq/ft 1800s Victorian farmhouse in the country and at the far side of the house (from the main, huge (120 gallon) vertical traditional hot water tank), the long run of hot water from the other side of the house just can’t maintain temperature well enough at the tap in our master bedroom bath. So although this huge tank “can” keep up, performance wise, I don’t like having to wait over two minutes for the pipes to heat back up as the water runs needlessly down my drain before I can hop into the shower or use hot water in my master laundry room sink, etc. Call me impatient. Anyhow, I decided to add this into the mix and located it right inside a utility cabinet inside of my master bathroom since we were in the middle of a remodel there anyways and I am so glad I did. Now, when I turn on the water, I have instant heat and man, do I mean instant (like less than 10 seconds, to any tap). Now my main tank no longer has to be burdened by supplying water to this portion of the house at all. Yet in the wall, I created a sort of hot-water supply switch, if you will, to allow me to later (if I so desire, for whatever possible reason), to switch to either system with the simple turn of a valve (since I had already went to the effort of running hot water from the main tank). Anyhow, that’s probably useless for this review. Regarding this product, if you’ve already got power in place and a cold-water supply line (which I did not), then installing it couldn’t be easier. Once installed (and the directions are clear, although almost unnecessary as it’s so straight forward – but then again, I’m a general contractor, so maybe I see things a bit differently), this thing really puts out the hot water. I can run my master bath walk-in shower, while my wife is right around the corner running hot water in the sink at full open or working in the kitchenette, and it just keeps going continuously without any sense that it’s struggling – no dips, no slightly less hot moments – nothing. Setting your preferred temp is very easy too, as the touch-screen control is simple and straight forward (Hotter? Push up. Colder? Push down) Overall, I couldn’t be happier with this little unit and therefore, gladly and highly, recommend it to others.
