Tankless Water Heater Electric, ThermoMate 8kW at 240 Volt, On Demand Instant Hot Water Heater for Point of Use, Self-Modulating Save Energy, Save Space, 1.56GPM at 35°F Rise

***UPDATE*** Month 1 after installing the unit, my electric bill went from $350 the prior month down to $230 the following month. So this has had clear and immediate cost savings for my electrical usage. Very happy with the results! ---------------------- I wanted to replace my traditional tank water heater with an electric tankless, so I did hours of research and comparing models and options. Finally settled on this unit in the 18KW size to fit my needs. I wanted to the next higher up but my electrical panel and home service capacity made that a risk choice. However, I'm delighted at how well the 18kw model works for my whole home use-case. Thankfully due to having an EV, I already had a conveniently located sub-panel installed. All I had to do was upgrade the capacity on that sub-panel, which was as simple as buying a larger breaker and making sure the existing wiring was up to the task. Ended up taking out the old 30amp breaker the tank water heater used out of the main panel, installing a 40-amp dual pole breaker there in its place, then upgraded my sub-panel to 100amps, and finally installing the second 40-amp dual pole breaker in the sub-panel. Ran all the 8 AWG wire to the location where I wanted to mount the water heater and used an appropriate amount of conduit and secured to the wall, which for me thankfully was only about 6 feet of distance. If you have complex electrical situations happening, definitely call in a licensed electrician. At this point it was an easy install to mount the unit on the wall, secure the wiring which was intuitive, and wall labeled. I didn't find any of the wiring or instructions to be wrong or confusing so thats a plus. The moment of truth then arrived, powering on the unit and setting the desired water temperature. A few quick tests and bingo, hot water. Its not been 3 days since the install and multiple showers, laundry, running the dishwasher, etc. No issues whatsoever. In fact, this unit outperforms the tank water heater we had before. My family now reports that they have to set the faucet to a less hot position than they did previous during showers. The water flow is perfect even when both showers are running full blast. We get consistently hot water and don't have to adjust it multiple times during the course of the shower as we did with the old water heater. Overall, very happy with the performance of this unit! My application is a single story, 2 full bath home, so I wanted something that could handle two concurrent showers and the occasional hand washing or laundry running at the same time. And I'm thrilled to say that it works for me better than expected. I also love that its a newer design that separates the heating element from the water flow path, which means less maintenance and easier repairs if something goes wrong in the future. Time will tell in terms of durability, but I was impressed with the quality of the build, its well-made and appears to be a thoughtful and clean design. Other units I checked out before buying this one looked sloppy, not as well designed. I'm so glad I chose this model. Obviously do your research on your electrical capacity, sizing for your use-case, etc. All I can say is that it works for me in my whole house use-case in Central Florida. Northern cold climates may need a more powerful unit. For me, I've got no doubt this will be more efficient and save me money on my monthly electric bill compared to the old unit electrical consumption. To top it all off, I got this on Amazon Prime Day using a deal and the cost was unbeatable for what I got in this unit. Super happy, will update the review in the future should anything else happen to change my mind.

So far, i'm liking this unit to its Rheem counter part... I have hard water we joke about it being liquid rock. But this unit so far has been rather nice, performs well, might take a couple seconds longer to warm up, but it gets it nice and hot.. Now its the longevity game i'm gonna see.. Looks like more electronics in this device than the rheem, but maybe they will hold up. Water flow is nice and the installation was pretty normal for the unit, 8 gauge wire etc, just wish it came preslotted for a larger single conduit to make my previous setup compatible, but after trial and error, I got it .... Its a nice small little unit, you can install it anywhere really.. I'd suggest somewhere near but far enough from the breaker panel as the wire is stupid expensive these days.. But if money isn't an issue put it where it works for you.

Several things you need know about this hot water heater , 1st it well not heat water at 2.5 gpm , the hottest I could get my water at that flow rate was 105 the unit states it should heat up to 127 . After experimenting with reducing flow rate shower heads...1.25 gpm the heat will flow at up to 127 depending on where you set it .I have 3 hot water outlets , kitchen sink , shower,bathroom sink. You can only use 1 at a time to achieve maximum heat...I'm fine with that, I did install a 4 gallon water heater under the kitchen sink , lucky smart move on my part . Would have given 5 stars but the numbers on the heat and gpm was misleading..this was installed in a 650sf cottage..

I bought this ThermoMate 14kW 240 VAC tankless water to replace a 50 gallon tank for a friend of the family that had burnt out. We tried replacing the burners, but they kept burning out, too. The wiring itself was questionable (I didn't install the old tank, I just had to try to fix it. I gave up and found this one on Amazon. Mounting was really easy due to its small size. I did have to run new #6 line, get a new StabLok 60A breaker, and create proper drains for the flush. Other than that, this was the easiest tankless install I've ever done. Their house is pretty small, so it produces the perfect amount of hot water for the single mom and disabled daughter. It functions perfectly and has great water flow. She does have a GoFund me to get help funding the replacement of all the wiring, interfaces, and circuit panels in the house. The house was wired back in the 40's, so there are no grounds to any outlets, lights, or electrical devices. She's had several electricians look at the wiring and all agree the home is a fire hazard. Even Idaho Power refuses to help to protect THEIR lines. Please DM me if you would like to help. I'll send you a link or look for "protect-letitias-home-from-fire-hazards".

So far so good! Working great and easy install.

I just paid $2300 to have a licensed plumber and electrician install and test this. Water is only luke warm now. The unit reads it will heat to 140 degrees F, but when I turn it up to 125 to get water hot enough to bathe in it simply sits at 95-98 and won't get hotter than 100 :( very upset, took a very cold and uncomfortable shower. Our previous water heater worked great, we just wanted to go electric. Even if I return this I will not get the 2k back I paid for installation. Why will it not heat? No support so far. We typically like to take very hot showers and baths here and bought this on the pretense that it would make hot enough water to fill both bath tubs at the same time but now the water does not get hot enough to even fill one tub. It's cold by the time it fills because the water only comes out 95 degrees. DO NOT BUY THIS IT DOES NOT WORK. please refund me, I'm now almost 3k in the hole and would re install my old working heater but they took it when they installed this one.

This tankless water heater has been a great upgrade!! It saves so much space compared to my old one. I’m already noticing the benefits of having instant hot water on demand. Installation was straightforward, the controls are easy to use, and I love the LED display. It feels efficient and modern, and I’m hopeful it will also save on energy costs over time 🙏🏼 Honestly, I wish I had switched to a tankless system sooner. If you’re considering one, this is a fantastic option - both in quality and price!

This tankless water heater offers excellent quality at an exceptional price. Installation was simple, and it has performed flawlessly from day one. What stands out most is the noticeable reduction in my electricity bill since switching to this system. In just two years, it has more than paid for itself. I took a chance moving from a traditional water heater to a tankless model, but it turned out to be one of the best decisions I’ve made.

Très bon produit. La qualité de fabrication est au rendez-vous et l’appareil fonctionne très bien une fois installé. La montée en température est rapide et la performance est stable, même lors d’une utilisation prolongée. Par contre, il faut savoir une chose importante : le coût d’installation peut facilement dépasser le prix de l’appareil lui-même. Entre l’adaptation électrique (24 kW demande une installation adéquate), le câblage et la conformité, il est essentiel de prévoir ce budget à l’avance. Cela dit, une fois correctement installé, le système est très efficace et offre un réel confort. Le format compact libère de l’espace comparé à un chauffe-eau traditionnel, ce qui est un avantage appréciable. Points positifs : • Chauffe rapidement et efficacement • Format compact et moderne • Bonne qualité de fabrication • Performance stable En résumé : excellent produit, mais assurez-vous que votre installation électrique est adaptée avant l’achat. Une fois tout en place, nous sommes très satisfaits du résultat. Je recommande.

We installed the 27KW water heater in a 3 season cottage. It required a significant upgrade to the electricity load in the house. Minimum 200 amp. It draws 115 amps when operating at maximum. It provides all the hot water you want in a 4 bed 2 bath house. We also have an outdoor shower. There can be as many as 8 people in the house at a given time as a seasonal rental. No complaints about the hot water this year. We had installed a smaller unit in an apartment elsewhere and it was an 11kw system. Not enough to fill a tub. Shower was fine. May need to upgrade that one. We are on Prince Edward Island and this unit should work fine year round with our well. I was warned by our electrician that the electric bill might be high. We have been monitoring that and it is fine and within what we would expect. Very happy with the unit. Our property rents from time to time and we can set the water temperature so nobody gets scalded by the hot water. Very handy. Recommended.

Très bon produit

It's a great heater and was easily installed.

ca ne remplis pas ces promesses. si le débit d'eau est trop fort, il n'arrive pas a chauffer au maximum. et quand je réduit le débit d'arriver d'eau, il n'y a plus assez de pression et quand je mets de l'eau froide, elle prend le dessus. en résumé, je suis très déçu de mon achat.
