  • Note: This 3kW 120V plug-in water heater is designed for low-flow use only, not suitable for showers or multiple taps at once. The output water temperature is affected by many factors, including the water heater wattage (heating capacity), inlet water flow and water temperature. For a better warm water use experience, we recommend that you consider our higher wattage model 6kW 240V first, which is hard-wired
  • LED Digital Display with Control Knob: This point of use water heater is very easy to use. 1 knob for power ON/OFF and temperature adjustment, offering a better use experience than others 3 little touchscreen buttons. You can adjust the temperature between 30C and 55C
  • Multiple Safety Features, Smart Design: This mini instant water heater is engineered with comprehensive safety protections, including overheat protection, leakage protection, dry heating protection, over-pressure protection, IPX4 waterproofing, and drop test certification. Plus, it has automatic fault diagnosis and constant temperature memory functions. It is very safe and intelligent to use
  • Efficient: This tankless on demand water heater under sink is suitable for 1 point of use. It can provide 24-hour endless warm water without the need for preheating, saving much compared to tank water heaters

Description

"The temperature adjustment is great which you simply do not get with a traditional hot water tank, and with a memory function built in we can be assured it will remain at the last setting we used it on and not have the need for constant adjustments to be made."

It saves space while offering 96% thermal energy efficiency, heating water only when needed, making it an excellent addition to kitchens, bathrooms, or under-sink setups. This 3kW 120V point of use water heater is not meant for hot baths or showers, but for dishwashing, hands washing, hair washing or bathing the baby puppy, it will do the trick without issue. The instant hot water heater only heats when the faucet is open, so you're not paying to keep a tank hot all day. Enjoy peace of mind with our round-the-clock expert assistance. Whether it’s a midnight installation question or a weekend use concern, our dedicated support team delivers prompt, professional solutions — because your comfort shouldn’t keep business hours. This water heater features leakage protection, overheat protection, dry combustion protection, high water pressure protection, etc. And it includes automatic fault detection and memorizes your preferred temperature settings, reverting to the last or most frequently used temperature when restarted. 96% thermal efficiency with no standby heat loss to save you time, water, and money.

Works great

Works great. Easy to install and fits in small spaces. Warms up quickly and has good flow.

Good
The dimensions are correct. The flexible washer was a nice touch. The OEM anode rod had a steel wire in the middle, which prevented piece of the spent anode rod from falling into the water heater. This anode rod did not have a steel wire. So, make sure to replace it before it's fully spent.

Protect your RV water heater
The anode rod in an RV water heater is a normal maintenance item if you do not have an aluminum tank. It is expected to deteriorate and needs to be at least inspected if not replaced on a regular basis. When the surface is badly pitted and portions of the rod are missing, it is time to replace it. I change mine out in late Spring as I prepare my trailer for a Summer full of camping. I primarily boondock and need to be sure my water heater is kept in good shape! This anode rod appears to be like any other, except for 2 things. It is longer than any I have previously purchased and installed and it has a gasket at the place where the threads meet the bolt head. This gasket is completely useless for my purposes as the threaded portion was longer than the receptacle so it never made contact with the tank, and I always use PTFE tape on the threads anyway. This anode is about .75in longer than any I have used in the past. It fit just fine and threaded in easily. Time will tell if it will hold up like its pricier name brand model. This is one of those items I always carry in my “boony” box for those :just in case” moments. If this holds up for the summer season I am likely to buy a couple more to have on hand. ... show more

Important Maintenence Item
These anode rods are important to replace regularly. This one is a good standard rod that seems to work fine.

Anodes...
I used one of these to replace the one that disintegrated in our RV's water heater. We have the larger 12 gallon water heater in our 42' Destination travel trailer. I respect these anodes for sacrificing themselves for the betterment of the water heater. If left unattended, the liner and heating element could deteriorate instead. These anodes are much cheaper to replace. Plus it forces us to do some maintenance - like flush the old stuff out and clean up the water heater housing along with ensuring not bugs or wasps have built any homes behind the cover or inside of the gas manifold! I'm not exactly sure if it's brass or some plated potted metal at the threads, but I like it better than my old one that was made of regular steel that was prone to rust. Other than that - not much to say about anodes! ... show more

Tankless water heater

I hooked this up to a single point (kitchen sink). Unit produces virtually no hot water, even with reduce flow coming out of the faucet. Live in the South, so incoming water is warm. Per the digital display I am only seeing two degree increase in water temperature.

Exact Replacement for My RV Water Heater
Our RV recently hit the 10 year old mark, which meant it was past time to replace the anode rod in the water heater. So when I saw this RV Water Heater Premium Magnesium 10" Anode Rod, I knew I wanted to test it out. Once I got the to the water heater, I removed the old one and there was nothing hardly left of it! This new one screwed right in and with some teflon tape, it sealed right up! I filled up the tank and pressurized the system, and no leaks! Replacing the old anode rod makes very good sense, because I'd rather replace the inexpensive the rod than replace the water heater. This worked perfect for our RV, very glad to get this and install it. ... show more

Don’t plan on instant hot water!
Number of Items: 1
Don’t plan on immediate hot water! It took 1 1/2 to 2 minutes of running water to get it hot and that translated to wasting a little over 2 gallons of water every time you wanted hot water! Also the temperature setting displays in centigrade only. Installation instructions were hard to interpret since they were not translated correctly. Thought it would be an improvement over the 2.5 gallon tank style that gave immediate hot water, but I was wrong… Going back to the tank style, so don’t waste your money. ... show more
