1. Bosch Tronic 3000 T 4-Gallon Electric Mini-Water Heater: Hot Water Anywhere!
The 4-gallon mini-tank heater is an excellent addition to any kitchen. With a total cost of around $325.00, it provides instant hot water and helps save energy and water consumption. The installation process may require some additional expenses, especially if the tank doesn't fit under the sink. In such cases, moving it to a nearby cabinet may be necessary, which can incur costs for hoses, connectors, and an extension cord.
One advantage of this mini-tank heater is that it allows you to run only cold water into the sink, ensuring that using hot water doesn't affect your gas water heater. However, it's important to note that there is a possibility of running out of hot water at the sink if too much is used at once. To address this, the temperature can be adjusted to prevent any shortage for personal needs.
The mini-tank heater significantly reduces the waiting time for hot water, especially in situations where the sink is located far from the main water heater. In the reviewer's case, the distance of 30 feet (40 feet including piping) resulted in a 30-second wait time, which was resolved with the installation of the mini-tank heater. Now, hot water is almost instantaneously available, taking only one second. The installation process itself is relatively easy and can be completed without the need for a plumber or electrician.
While demand water heaters may seem like an alternative, they come with a higher price tag. In addition to the cost of the unit itself, a new dedicated electrical line with a breaker would be required, resulting in expenses of around $1500 or more for professional installation. Retrofitting a demand water heater is even more costly and usually only makes sense when replacing the main water heater. In the reviewer's case, they still found value in having the mini-tank heater due to the distance issue.
For those considering this mini-tank heater for standard under-the-sink installation, several additional items are needed. These include 2 ½" NPT to 3/8" compression hoses (2 feet long), a 3/8" compression tee, a 3/8" female to female connector (with male ends), and an aluminum water heater pan. These components are used to connect the 2-foot long 3/8" hose to the hot water hose for the sink tap.
In the reviewer's installation, they opted for different components due to their specific kitchen layout. This included 2 ½" NPT to 3/8" compression hoses (1 foot long), 3/8" dishwasher supply hoses (6 feet long), additional 3/8" female to female connectors, a 3/8" compression tee, a 12-gauge extension cord (8 feet long), and an aluminum water heater pan. These modifications were necessary to accommodate the distance and ensure proper connection.
Depending on the kitchen setup, it may be advisable to plumb a PVC pipe into the over-pressure valve and direct it towards a floor drain or outside. This is particularly relevant for kitchens with waterproof tile floors, as any potential overflow can be easily mopped up.
During the installation process, it is recommended to have a good flashlight or headlamp and a couple of adjustable spanners (small crescent wrenches) on hand. These tools will assist with the proper connection and adjustment of components.
It's worth noting that the 7-gallon version of this mini-tank heater may require an electrician for installation. However, it does not necessitate a new or dedicated circuit, as it still only draws 12 amps. If comfortable with electrical work, connecting the electrical line to the existing box should be manageable. It's important to consider possible additional costs for connectors or a larger electrical box. Some municipalities may also require a permit and inspection for this type of installation, as it involves adding an electrical circuit. While the 7-gallon version offers greater capacity, it takes longer to heat and requires more space.
2. Kenuos Compact Electric Water Heater – Instantly Hot!
The small 2-gallon water heater I purchased has been a great addition to my kitchen sink. With the water heater located in my basement, which is 50 ft away from the kitchen sink, I used to waste a significant amount of water waiting for hot water to arrive at the faucet. This resulted in approximately 150 gallons of water wasted every month. However, by connecting the hot water line to the "cold" inlet of the heater and reheating it, I now have instant hot water at my kitchen sink. It has been a great appliance that has effectively solved the issue of waiting for hot water.
One drawback I encountered was that the unit was slightly too deep to fit behind the existing drain plumbing, which required me to use more under sink storage space than I initially wanted. Additionally, the water heater does not display the water temperature, so I have to manually adjust it until it reaches a comfortable temperature. It is important to note that it can get hot enough to scald, so caution should be exercised. Despite this, the water heater is not designed for shower use but rather for under the sink, dishwashing, and other similar applications.
Installation was relatively simple, and I am pleased with the overall performance of the water heater. It quickly heats up after emptying the initial two gallons of water it holds. Although I initially intended to install a larger tank, it unfortunately did not fit under my sink. However, I am highly satisfied with the instantaneous hot water it provides for handwashing and cleaning tasks.
3. Rv Tr Compact Hot Water Heater With Stainless Steel Hoses

A friend recommended this water heater to me, mentioning its stainless steel structure, ensuring durability and longevity.
It is important to note that this water heater is not suitable for bathing due to its limited water capacity. If you require hot water for bathing, I would recommend investing in a larger water heater.
I am extremely satisfied with this product, not only for its functionality but also for the excellent service provided. As winter approached, my wife was constantly complaining about the lack of hot water. However, this small water heater for dishwashing has resolved the issue. During the installation process, I made a mistake by forgetting to turn on the water while running the water heater. When I noticed a strange smell, I quickly realized my error. I contacted the customer service team using the provided contact details on the package, and they promptly responded with a solution. They informed me that the water heater has a protection mechanism, and all I had to do was open the gray cover and press the white button to restart it. Thanks to their patient and prompt assistance, the hot water is now working flawlessly.
