Review: Works great so far! - Easy to install and works fine still after multiple months of use. I use this for my garage sink and don't keep it set very hot. Just wanted to be able to wash my hands with warm water in the winter, which it does very well. Good value for the money. If I were installing in the house, I would recommend using some kind of pan under it with a water sensing alarm in case it ever developed a leak, which many of these inexpensive units seem to be notorious for
Review: Inexpensive small capacity water heater - Nice little water heater. It gives a minute or so of set temperature water and then its warm water. It does as expected. It’s a small capacity water heater and it’s heating really cold water with a single phase 20amp circuit. Easy to install as well. The adjustable set point is nice and it also displays the actual water temp. We keep it set at 120. Comes with a P&T safety valve as well.

### ⭐⭐⭐⭐ Working beautifully for the first couple of weeks...
*by E***E on December 26, 2025*

I installed it inline with the home hot water system and the water heater seems to be a very good unit... quick recovery, constant temperature, informative display. Yet, as other reviewers have mentioned, there seem to be some installation issues to deal with. Notably, the safety "pop-off valve." NPT threads are supposed to be tapered, increasing in diameter as the pipe is tightened to create a tight connection. But on this unit, the supplied pop-off valve has a rather long threaded shank, even with bit of a smooth material extending past the threads at the end. That wouldn't be a problem, except that the tank inlet for the valve has a pronounced inside lip at the bottom of the threaded inside threads. Thus, the valve bottoms out on the lip before the taper enters far enough to even come close to sealing. I considered remedies, other than wrapping the valve with an "ungodly" amount of Teflon tape, as some have suggested. I considered grinding off the end of the threaded valve to let it go in further, but the extended temperature probe made that impossible. Then going to the local hardware and plumbing store with the heater, hoping to be able to buy a pop-off valve that would fit better... and he DID have one, but rather expensive and relief pressure higher than the one supplied. At his suggestion, I did attempt to solve the problem by both INSERTING A RUBBER WASHER into the fitting... AND wrapping the valve with a copious amount of Teflon tape. Inserted the valve hand tight... and so far, so good. Having gotten over the little hurdle, I would buy again... providing the unit proves dependable.
