I Tested And Reviewed 10 Best Point Of Use Water Heater (2023)

I have been a loyal user of Fogatti water heaters for quite some time now, and I have always been satisfied with their performance. Recently, I purchased another Fogatti water heater for one of my new tenants who needed an under sink water heater for a fourth bathroom. This particular bathroom was far away from the conventional heater in the garage, so the under sink water heater was the perfect solution.

The installation process was incredibly easy. All I had to do was connect the cold water-in and hot water-out under the sink. However, it is important to note that you will need a power outlet, which is not typically found under bathroom sinks. So, make sure to get some help to set up the power outlet before installing the water heater. Additionally, I appreciate that the Fogatti water heater comes with a Temp & Pressure Relief Valve, which saved me an extra $20.

The 4-gallon capacity of this water heater is more than enough for a variety of tasks. It works seamlessly with the conventional hot water heater, and there is no need to wait for hot water or waste any in the process. This was particularly beneficial in my situation, and I am glad to have this as an additional feature.

Another reason why I chose the Fogatti water heater is because of the brand's reputation. I have always had a positive experience with their products, and this water heater is no exception. It heats up fast and consistently in my RV, and I have never run out of hot water during a shower. However, I have not intentionally pushed it to its limits to see if it would run out of water.

The installation process for this water heater was a breeze, and I had it up and running in no time. I am currently using it in my RV, and it is perfect for long showers. If I ever needed to buy another water heater, I would definitely choose Fogatti again. Although, I would recommend opting for the 8-gallon capacity if you have the need for more hot water. Personally, I have no regrets with my purchase, and I am hoping that this water heater will last me a long time.

I purchased this small RV heater to use as a quick water heater in my kid's bathroom. It's the perfect size to fit under the sink, and I appreciate the temperature control knob, which makes it easy to adjust the heat. However, one thing to note is that it requires double 1/2 Inch FIP Connectors, which may not be readily available in local hardware stores. Thankfully, a quick search on Amazon solved this issue.

I also installed this heater as a replacement for my RV water heater. While it is smaller than the original, it is still more than sufficient for my needs. It quickly heats up the water to the desired temperature and holds it for a long time.

Upon receiving the heater, I was a bit skeptical about its performance. However, I am pleased to say that it has exceeded my expectations. My husband installed it today, and it is working flawlessly. I particularly enjoy using warmer water for brushing my teeth, and this heater provides just that. Additionally, the water pressure is normal, which is exactly what I need.

I also utilize this heater in my outdoor bar sink. It efficiently produces hot water within a short span of time and fits perfectly under the sink without occupying too much space. Moreover, it offers the best price compared to other similar products.

Furthermore, we have connected this heater to our outdoor washer, where there is no water tank. It serves its purpose perfectly and was easy to install.

I recently installed the Ariston 2.5-gallon water heater in my home and I have to say, it has been a game-changer. As someone who loves to cook, I constantly need hot water for various tasks like rinsing my hands, cleaning utensils, and even rinsing wine glasses. This water heater has provided the perfect solution for all these needs.

One of the standout features of this tank water heater is its ability to provide hot water at a very low pressure and volume. Unlike many tankless water heaters that require a certain flow rate to start heating, this tank can provide hot water even at low volumes. This means no more waiting endlessly for the water to get hot.

I was also pleasantly surprised to learn that many people are unaware that their dishwashers and washing machines are filling up with cold water, even when set on the "HOT" water setting. This is because the water from the main line is not hot yet, and by the time it does heat up, the machine is already full. With the Ariston water heater connected to my incoming hot water line, I no longer have to worry about this issue.

Installation was a breeze, and I connected the tank to my kitchen sink and dishwasher using a "T" adapter. I was able to power both appliances with a single outlet, and they can run simultaneously without tripping the breaker. The compact and attractive design of the water heater is also a plus.

The performance of the Ariston water heater has been flawless. It heats up the water without making any noise, and it maintains temperature really well. Even if I need more than the 2.5 gallons of hot water stored in the tank, the refill water flowing from my tankless main water heater will already be hot by then. This not only saves money and electricity but also reduces wear and tear on the main unit.

Before purchasing this water heater, I often found myself running the sink until the water was adequately hot, only to realize that over two gallons of water had gone down the drain. This is a common issue in kitchens where incremental and low-volume hot water is frequently needed. The Ariston water heater eliminates the need for waiting and wasting water, making tasks like quick hand rinses a breeze.

Whether you choose the Ariston 2.5-gallon water heater or a mini point-of-use tankless unit, you can expect instant hot water. It truly is a game-changer. I have been so happy with this product that I even offered to install one for a family member who has a similar water-wasting setup.

Not only does the Ariston water heater add convenience to your daily life, but it also saves water and promotes sustainability. It's a wise investment that will have a positive impact on both your family life and the environment. Trust me, you won't regret adding this to your home. Don't wait any longer – make the decision to upgrade your water heating system and enjoy the benefits it brings. Best of luck!

I recently purchased the RV water heater anode rod and I must say, it fits perfectly and comes at a bargain price. There isn't much more to say about it until I actually use it for routine replacement in a couple of years. If it manages to prevent corrosion and do its job effectively, then I will be extremely satisfied.

I was in need of a replacement for my Jayco and this product turned out to be the perfect fit. I hope it lasts longer than the original one, but overall, I am pleased with my purchase. It came with everything I needed for installation, except for the tools, and it only took a few minutes to get it up and running again.

When I received this product, I was amazed by the price point. Despite being more affordable than other models, it works just as well. I am aware that these rods typically don't last more than one season, so getting a rod at this price that performs just like the expensive ones is definitely a win for me.

This RV water heater anode rod does exactly what it's supposed to do. The kit includes the rod and some thread tape, which was a nice freebie that saved me the trouble of searching for it in my toolboxes. The rod fits perfectly and works great.

I finally replaced the anode rod in my camper, and even though it's not that old (I bought it new in 2018), these things tend to rust out quickly due to the constant heat temperature shifts that campers are exposed to. However, I had no issues removing and replacing it with this product. It was easy to install and seems to be the right size. So far, I haven't encountered any problems. Overall, it's a great product!

I recently installed the hot water heater under my kitchen sink to address the issue of waiting for warm water to reach the sink from a distance of 90 feet. The installation process was a bit challenging due to the inaccessible plumbing in my house, but with the help of sharkbite fittings and some copper cutting, I was able to route the hot water line under the sink. I also added a bypass valve and valves on the in and out lines for future convenience.

After the installation, I was pleasantly surprised by the results. With the thermostat initially set to the maximum, it took only a second to get very hot water at the faucet. I quickly adjusted the temperature to a comfortable level, and my wife was thrilled with the instant hot water. Although the installation would have been easier for a typical plumbing setup, the overall outcome was satisfactory.

In terms of performance, this hot water heater has won the reviews war. It efficiently heats water from cold to hot within a very short time, providing instant hot water for most quick needs. The tank, which holds over a gallon of water, is sufficient for regular usage. However, it's important to note that the hot water supply will run out eventually, requiring a short wait for it to replenish.

I opted to have a plumber install the unit due to the specific fittings required for my kitchen plumbing. However, it is possible to install it yourself if you have the necessary skills. The temperature adjustment is simple, requiring just a twist of the dial. Mounting the heater requires ample space under the sink, so accurate measurements are necessary. Additionally, an electrical outlet under the sink is needed for power supply.

In my case, the installation process took around 3 hours, including a trip to the hardware store for additional parts. The convenience of having instant hot water far outweighs the effort spent on installation. By tapping into the existing hot water line, I was able to connect the heater to the inlet side without any major issues. I also added a bypass valve as a precautionary measure. Although the plumbing setup may not strictly adhere to code, it functions effectively for my needs.

This hot water on demand system is incredibly easy to install, so much so that even a child could do it! It's the perfect addition to any RV, especially for those who struggle with their water heater keeping up during the winter months. With this system, the incoming water is heated to 120° and then routed to the water heater, bringing it up to a toasty 140°. This means you'll have endless hot water and can finally enjoy that dream of a 30-minute hot shower in the winter. No more waiting for the water tank to recover or doing chores one at a time!

The installation process was a breeze, thanks to its 120 volt and 40 amp power requirements. Just a few minor adjustments and it was good to go. After the work was done, I felt like I had welcomed my rig to the 21st century. Gone are the olden ways of limited hot water supply.

Not only is this system easy to install, but it's also great for small campers. One user mentioned that it replaced their worn-out gas water heater without any issues. Another user, who had never installed anything like this before, found it incredibly easy to install and it works like a charm. Just make sure to read the directions thoroughly before installation.

If you're looking for a hot water system that works quickly and efficiently, this product is for you. It takes only seconds for the water to get hot, and it can even get super hot if desired. The product fits everywhere and heats the water perfectly. I highly recommend it and give it a 5-star rating.

I had a bit of a hassle with the first heater I received as it was dead on arrival. Unfortunately, there was no way to test it until it was installed. However, I contacted Amazon and they promptly resolved the issue by sending me a replacement unit, which worked perfectly. I must say, the customer service was excellent.

Although the heater comes with a flow reducer, I didn't find it necessary to install it. I live in Virginia where the average cold water inlet temperature is around 60°F, and this heater had no trouble getting the water hot enough for comfortable handwashing. However, I do not recommend using it for a shower. Personally, I have it installed in my garage deep sink and powder room, and it serves its purpose very well. It was definitely a great purchase.

The wiring and connections of the heater appear to be of high quality. It also came with a good mounting template and clear instructions, making the installation process easier. I would not hesitate to recommend this product to my friends and family.

There is a "feature" of this unit that I wish had been better documented. Inside the unit, there is a tiny impeller in the inlet coupling/line that needs to move freely up and down its shaft. This impeller triggers a relay to turn the heater on and off. Unfortunately, this information was not included in the documentation provided. It caused me some initial frustration after replacing the faulty unit.

In my case, debris such as PVC dust, glue, or junk from the original plumbing got inside the inlet and caused the impeller to get stuck. As a result, the heater never came on. I had to call the company for assistance and realized I had to completely uninstall the unit to clean the impeller. This was quite inconvenient, as my plumber had not used compression fittings, requiring everything to be cut away and reinstalled. I would advise flushing your water system thoroughly before connecting it to the unit to avoid any potential issues like this.

The Rheem 6KW water heater is an excellent choice for small businesses or for those looking to save energy and space. I recently had a forty gallon water heater go bad at my business, and I found that the Rheem 6KW was the perfect replacement.

One of the standout features of this water heater is its display, which shows the temperature of the water leaving the heater. This allows for easy monitoring and adjustment of the water temperature. Additionally, the on/off switch is a convenient feature that adds to the overall user experience.

The quality of the cabinet is also worth mentioning. It is well-built and aesthetically pleasing, making it a great addition to any space. The water connection fittings are heavy-duty and reliable, ensuring a secure and leak-free connection.

Installation of the Rheem 6KW was a breeze, taking less than 30 minutes with the correct fittings. The compact size of the unit is a major advantage, as it can be easily mounted on the wall, saving valuable floor space. This was a significant improvement over my previous tank water heater, which took up a lot of space in the laundry room.

In terms of performance, the Rheem 6KW does take a little time to reach the desired temperature, but it does get hot enough for most needs. The speed at which it heats up can be increased by reducing the flow rate of the faucet. Overall, I found it to be worth every penny.

Another happy customer has found the Rheem 6KW to be the perfect solution for their extra kitchen where they do canning. The constant flow of hot water at 121 degrees Fahrenheit is ideal for their needs. The compact size of the unit allows for convenient storage under the sink.

Lastly, it is worth noting that Rheem is a trusted brand known for its high-quality products. The build quality of their devices is exceptional, and they undergo rigorous testing before being shipped. This ensures that customers receive a reliable and durable product. It is clear that Rheem is a brand you can trust, and it is worth investing in their products rather than opting for cheaper alternatives.

I am extremely satisfied with the Thermoflow UT10 2.6 gal heater. It has completely eliminated the wait time for hot water, making tasks that require a small amount of hot water quick and easy. Not only does this save on water waste, but it also ensures that hot water is readily available at the sink without any delay.

The installation process was a breeze. I purchased two units and used a 1/2 inch NPT flexible faucet connector for each one. The installation was straightforward, and I had no trouble setting them up. They have been running smoothly for a couple of months now, and I have not encountered any issues.

One of the standout features of this heater is its even heating distribution. Unlike other products that require the user to protect themselves from hot spots by adding a pressure valve, the Thermoflow UT10 heats evenly without creating local steam from a too hot heating element. I was pleasantly surprised by the lack of noise from the heating elements, and the heat-up time was very reasonable.

The temperature control is smooth and offers plenty of range, allowing me to adjust the water temperature to my preference. The size of the heater is also a plus, as it can be placed on the counter floor instead of requiring wall-mounted installation.

The only minor inconvenience I encountered was the tank's 1/2" NPT fitting. In the US, this is referred to as a "compression fit," which is different from the typical FIP fitting. Most sinks and faucet connections are smaller, around 3/8". However, I was able to find a 1/2 to 3/8 compression adapter at a local hardware store to solve this issue. Additionally, I needed a longer line than the standard 30" ones available, but I found a 4-foot line with 3/8 compression on both ends on Amazon, which was a perfect fit.

I recently purchased a water heater for my bathroom sink, as it is located far away from the main water heater in my house. After researching and comparing various options, I decided to go with this particular model and size. And I must say, I am extremely satisfied with my purchase.

The installation process was fairly simple, although I did require the assistance of an electrician. Once installed, the water heater provided hot water instantly, saving me a significant amount of time and water waste. The compact size of the unit is also a plus, as it is hardly noticeable under the sink.

In terms of temperature control, I have found that the water can range from warm to very hot, and it seems to be endless as long as I keep it running. I haven't experienced any issues with the temperature so far. However, I am unsure about splitting the water flow between multiple devices without compromising the efficiency of the water heater. It is worth noting that there are larger models available for higher water flow.

I initially purchased two units but ended up returning one as I realized I didn't need it. The customer service team was prompt, friendly, and generous throughout the return process. They even accommodated my request to keep the second unit, despite initially returning it.
