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

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 received the new tankless water heater, heated it, and installed it. This was a replacement for one installed approximately 6 months ago. Worked perfectly the first time. Purged the system of all air and turned on power. Had hot water with no issues. Set the temperature at our desired level and tested. Been in for 3 days, and we immediately noticed the difference. The old one had flow issues. Had to reduce the flow so much that it was almost a trickle. This one, on the other hand, worked as expected immediately. I washed dishes and found the water was so hot we had to use cold water so my wife could rinse. We have no regrets other than wishing we had ordered this one to start. I would not hesitate to buy this one again.

This was installed in my camper van and works fine so far.

I've had this for a few months now. My far bathroom used to have very cold water, but this device provides instant hot water. It was very easy to install, and I connected it to my hot water line.

With our tankless water heater we wasted a lot of water in the kitchen waiting for the water to get hot. Now that isn's a problem. Instant hot water. I still have plenty of room under my sink. We are very happy with this water heater. I would recommend it to friends. ( In fact I already have)

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

It was great product.In my case it just didn’t fit the size i needed for a reduce space but my review has to be 5 stsrt because it’s really a good product and the seller sent it on time as he said.Thank you.

We use this for a sink and the washing machine. Our washer has sensors that stop the machine if there is no hot water, and my wife complained she could not clean the washer without hot water, so I bought this. It works fine. Did not notice a spike int the electric bill and best of all the wife has warm water to do the laundry.
