Electric Mini Tank Water Heater UL Listed, ThermoMate 2.5 Gallons Small Under Sink Water Heater for Point of Use Instant Hot Water 110V 120V, Wall or Floor Mounted, ES250

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

It’s only been running for less than a week so that part I am not able to address. It is performing very well. Very easy to install.

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!

We put this water heater in our 26’ camper. Because we prefer electric over gas. Works great. Warms up pretty quickly after using all the hot water. The video was very helpful. We were able to get installed very quickly.

Still working over a year later. Husband did need to quickly fix a broken wire, but back to heating. Very fast and small size works great under kitchen sink.

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.

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

Purchased this when my instahot died and could not swallow the price for a new unit. This tank installed very easily with standard fittings and came with its own pressure value. I have it under the kitchen sink where is small size is important (1.5 gallon version). It is feed from my hot water heater that usually takes a minute to get hot water to kitchen sink. Now, have hot water in seconds and, while it cools a bit, it is hot enough to do the dishes while the feed line still has cold water. I will be installing these in bathroom cabinets as soon as can do the electrical work needed.
