Overall, I am highly satisfied with this product and would give it a 5-star rating. I highly recommend it to anyone in need of an efficient and easily installed hot water system.
2. Ecotemp Digital Tankless Water Heater For Kitchen – White
I recently purchased this tankless water heater for my detached garage, where I didn't have access to hot water before. I must say, it has been a game-changer. The installation was fairly easy, and it works great. However, it's important to note that this heater, like any heating element device, requires a significant amount of power. It's best to have it on a dedicated circuit to avoid tripping any breakers. Other than that, I am extremely satisfied with its performance and the affordable price.
I specifically chose this tankless water heater for a single washing tub basin fixture, and I'm happy to report that it has exceeded my expectations. The unit is compact and designed for 1/2" NPT threaded water connections. While it did require some effort to re-plumb the water lines and run the electrical, the end result was definitely worth it. The large LED display on the front of the unit is a standout feature, as it makes adjusting the settings a breeze. The only minor drawback is that the temperature readings are only displayed in Celsius and cannot be changed to Fahrenheit. However, this is not a deal-breaker for me. Overall, this product has worked exceptionally well for my specific application, and I highly recommend it, earning it a well-deserved 5-star rating.
For small applications like a sink, this little hot water heater is fantastic. I love the convenience of having instant hot water whenever I need it. It's a great addition to any household.
I was pleasantly surprised by the fast shipping of this water heater. Despite living in a rural area, I received it the very next day after ordering. The packaging was secure, and the product matched the description perfectly. Installation was a breeze, taking only 20 minutes. I couldn't be happier with the overall experience, and if I could give it more than five stars, I would.

3. Bosch Electric Tankless Water Heater – Eliminate Time For Hot Water – Easy Installation
I am extremely satisfied with my purchase of this unit. I have been using it for the past six months to supply hot water to both my bathroom shower and kitchen sink. It works well for taking a shower, although I have noticed that if my wife turns on the hot water in the kitchen sink, the temperature in the shower drops significantly. This unit can only handle one demand at a time, which is sufficient for our simple lifestyle in our 600 sqft house.
The only issue I have encountered is with the water flow in the bath-tub. The flow is too strong for the unit to heat the water adequately, so I had to manually adjust the hot water valve to slow down the flow and allow the water to heat up to a suitable temperature. As a result, it takes a bit longer to fill the bath-tub, but this is not a major inconvenience for us. After researching various units, I found that this one had the best reviews. Even if it stops working after a couple of years, I would still purchase it again and install a new one.
The unit works great and requires a dedicated circuit with a 50 amp breaker. We installed it in our barn, where it is not used on a daily basis. We chose a tankless water heater due to past issues with small tank water heaters that tend to develop a smell if not used consistently. Our water temperature in the winter is typically around 45 degrees F, and this water heater gets very hot. I had to adjust the temperature to prevent burning my hands and did not bother measuring the water temperature. As we approach summer, I have further adjusted the temperature, which is a simple process. I highly recommend this product, but it is important to do your research and ensure that you have the proper wiring in place before ordering.
I initially purchased this unit (model US12) for my kitchen, but my contractor friend advised me that it was overkill and recommended a lower-powered and cheaper model (US 7) for the kitchen sink and dishwasher. So, I saved the US12 for later installation in my bathroom/laundry room. However, when I finally got around to installing the unit in my bathroom, it failed immediately. Thankfully, Bosch tech support was outstanding and promptly sent me a new unit within a week. Once I installed the new unit, I discovered that the cheaper US7 model actually provides hotter water with less power consumption. When both units are adjusted to the maximum temperature output at the same flow rate, the US7 consistently delivers hotter water while only drawing 30 amps, compared to the US12 which draws 50 amps. Both units are set to high.
4. Thermoflow Minitank: Instant Hot Water Heater For Sinks

Compared to other options on the market, this particular model stands out. Its compact size allows it to fit seamlessly under the sink without taking up much space. Installation was made easy with the help of an electrician, and the hook-up process was straightforward.
One of the standout features of this water heater is its ability to provide hot water immediately. Whether you prefer warm or very hot water, this device can accommodate your needs. It also offers an endless supply of hot water, ensuring that you never run out as long as the unit is running.
While the reviewer did not mention the specific size they purchased, it is worth noting that larger models are available for those who require a higher water flow.
The customer service provided by Thermoflow was exceptional. They were prompt, friendly, and generous when the reviewer had to return one of the units. Even after some initial communication issues, Thermoflow was able to resolve the problem and provided a brand new replacement unit.
5. Camplux Remote Control Rv Tankless Water Heater (Black)
The Quick Swap tankless water heater is an excellent upgrade for travel trailers, providing a reliable and continuous supply of hot water. With its integrated door/flange, weatherproofing becomes effortless, making it suitable for all weather conditions.
One of the standout features of this unit is its impressive power of 64k BTUs, allowing it to raise the incoming ground water temperature from 33 to its maximum of 124 at 1.5GPM. This makes it ideal for residential use, easily meeting the demands of a normal shower head.
The anti-freeze feature is a brilliant addition, utilizing propane instead of electric heat strips commonly found in residential water heaters. This ensures reliable performance during colder months.
The installation process is simple and straightforward, with only a few modifications required. The unit fits perfectly into the designated spot, and the clear instructions provided make it easy to understand and follow. The digital controller allows you to set the desired temperature, providing very hot water as per your preference.
The quality of this tankless water heater is top-notch, with a sturdy build that instills confidence in its durability. The unit is designed to provide 2.6 gallons of hot water on demand for up to 20 minutes, which is more than sufficient for showering or other tasks requiring hot water.
