This heater was easy to install, works as expected. Provides instant hot water. For my needs it was well worth the money.

Small capacity but gets the job done. Just enough to make the cold water sandwich manageable. The run to the on demand heater is far but now we can live with it. If I had more room under the sink, I would've bought the bigger capacity heater.

I am in a house I just recently bought. The gas company is super unfriendly, their "inspector," is not a nice person and after clearing the house with the gas on a few months ago now says all the gas lines must be replaced? They're not even old. So, yeah, bye bullying GAS Company! I yanked out the gas stove and put it on Craigslist the next day, lovely electric cooktop now installed. We have options, today. Anyway, I researched and researched, and found this portable electric HWH that consumes low amps and is 110v! I have to admit, the box arrived and I was intimidated. I got online and started looking for "all the stuff," I'd need to install it, lines, fittings, even tools. Imagine my delight when I discovered I needed nothing other than what was already there in the house and some teflon tape I already had. Even installing the pressure relief valve (they provided it, thanks so much) was a breeze. Start to stop, it was making water hot less than 30 minutes after I opened the box. I'm using this right now in a shower. I have to spray, suds, rinse, but it SO beats ice cold showers. My plan will be to use this unit eventually in my outdoor bathhouse, but today, it's saving my life by providing me with a hot shower. So, so happy I bought this. Update 5/12/2025 - Still working great, used it this morning!

Very compact and looking nice. I finally have hot water quick in my entrance restroom sink. Actually makes for a great comfort in cold months! Temperature gauge is not accurate though, whatever level you set it, sometimes it’s hot, sometimes just warm, so inner thermostat is not that good if I compare to my Stiebel Eltron heaters (they wouldn’t fit the tight space). Otherwise hope for long service.

Now updated - purchased this 1 year ago. It installed correctly but there was no manual. There are YouTube instructions. Runs perfectly. Timed it for hot water and it ran 7.5 minutes. I took a ten-minute shower and my hubby a 15 minute shower at first. We figured out to keep it hot for up to a half-hour shower which is too obvious. Just turn off the shower while soaping up again. I say, works better than described. My husband says it was easy to install, even at 70 y.o. It's easier for the average person with the right equipment. For anyone older, you might want to hire someone younger with a few skills to hook it up. We found it takes a bit less time to get the water heated by putting it on the halfway point, wait for the red button, then turn it to max, and you'll have plenty. This is also perfect for under the sink as well. Leaving it on to run dishes runs out of hot water faster. We already turn off the faucet while washing dishes to save electricity so this is an easy choice for us. Definitely would purchase again.

I URGE ALL WHO PASS THIS AY TO READ OTHER 1 star reviews. >This 4+ gallon unit is a "Bare bones" unit. No extra hoses, or elbows, etc. Except for pressure relief valve, ALL other valves, hoses fittings, and attachments must be purchased separately at hardware store. >Upon install unit was set to operate around 115 degrees. >I invested time and materials to have this unit in our kitchen to reduce time waiting for hot water. >Entire house has been upraded to PEX as well as whole house 3 stage filter. No rust, calcium or other debris in existing water pipes/system. ISSUES FROM DAY ONE: 1. Unit did not keep consistent heat. Sometimes warmer, sometimes colder when hot water turned on. Sometimes it did not seem to heat at all. 2. At around 18 hours after install, it would pop the 20 amp circuit breaker. 3. After reviewing another one star review that showed rust in the tank and connecting pipes, of which I found as well. 4. AT first use, after warming period of at least an hour, I and then turned on the hot water and measured how much water volume was actually hot. After about 1.5 gallons of flow, the temperature dropped off quite a bit. 5. After 3 days of this, I disconnected and dropped it back to Amazon. Waiting for refund. DO NOT BUY

Top notch. Made in America and works great! Would buy again over any of the Chinese ones. I bought a Chinese 4 gallon waterheater and the heating element burned out in a little over a month. You get what you pay for. I would fully recommend this water heater I got the 4 gallon and it works great.
