I've had my Ariston 2.5 gallon water heater installed (I did this personally, big fan of DIY projects) for 4 mos. As an avid cook, I am constantly needing short bursts of hot water to rinse my hands, clean utensils, rinse wine glasses, etc. This is the solution. Never a better home improvement idea has been fulfilled that I can even compare to installing this water heater. Because this is a tank, it can provide water at a very low pressure/volume. The sort of low volume that would otherwise not trigger many tankless water heaters to start heating. More importantly, no more grief as you wait endlessly for the water to get hot. Most people aren't even aware that their dishwashers/washing machines are filling up with cold water (on the "HOT" water setting) because the water from the line is not hot yet and the machine will most likely be full by the time the water is hot. I have my tank connected to my incoming hot water line (from the tankless main unit outside my house) to my kitchen sink/dishwasher using a "T" adapter. I power both with a single outlet also with an adapter. The two can run simultaneously as I've discovered without tripping the breaker. This is truly a great product. It has performed flawlessly, it's compact and genuinely attractive. There's no noise while it's heating up the water and it maintains temperature really well. The other cool thing is that if I'm needing more than (2.5 gallons) what's in the tank, the refill water flowing into it (from my tankless main water heater) will be hot by then. Saves money and electricity, wear and tear, etc. Again, in my case, this unit serves as a flow through ('in line") source of hot water. Before purchasing this, I ran the sink until the water was adequately hot and discovered over two gallons of water went down the drain. In a kitchen, it's really common to require incremental and low volume hot water. Constantly waiting and wasting just to do a quick rinse of your hands is enough to justify adding this to your life. However, saving water and adding convenience is what sells it. Remember, this unit is not coming up to temperature gradually, it is storing water at a constant temperature. Whether you go this route or choose a mini point of use tankless unit, you get hot water instantaneously. It's a game changer. I've been so happy (and enlightened) with this that I've offered to install one for a relative who has the same water wasting set up. It's one way (as is this review to inspire people to get one of these) to pay forward wisdom that changes the planet for the better. Don't procrastinate. This will be one of the best decisions you'll make to add convenience to your otherwise crazy family life like mine. And you'll be patting yourself on the back wondering why you hadn't done this a long time ago. Best of luck!!! Review: Great product, easy to install, arrived quickly, and earlier than expected. - This is a great little heater. My camper came with one installed when I purchased it 8 years ago. No telling when that one was bought. Mine stopped working, so I got a new one. It came with clear directions; easy to remove the old one and hook up this one to the already existing PEX piping, Watched several YouTube videos about this little heater before in stalling it myself. (female 73 yrs,) If one doesn't have the PEX piping, there are videos for that also. Mine lived a nice long productive life considering I have well water and did not know to flush it out once a year. It gives me instant hot steaming water at the sink, hot enough to make tea and instant coffee. I love it. I had the option to clean or replace the corroded heating rods, but considering the low price I simply replaced the entire heater. ## Features - Compact and Versatile Design: The Ariston Mini-Tank Electric Water Heater is ideal for supplying heated water to single sinks in small spaces like RVs and under sinks.

I'd like to split the toilet line, install this, then attach my sprayer bidet.** A: Yes you can, but you know, you can buy a bidet with a water on demand heater built in it ! much better and you are not reheating 2.5 gals of water after each use. Check on Amazon or Wish for a bidet, it is not expensive . **Q: Looking to install 4gal on adu as a booster. located 20-30 ft from tankless in main house. would this be a good fit for shower booster? thx** A: Exactly what I am using it for, a buffer tank. Here is the thing to keep in mind: make sure the thermostat temperature at the main supply is set lower than the mini tank. The reason; you really don't want to flood the mini tank with a higher temperature water when it's thermo is set lower thus damaging the thermo in the mini tank. The manufacturer mentioned this in one of the installation manuals. It makes sense. I have installed 2 of these units so far and cannot say enough about them. Use the sharkbite fittings and your kid can install it. Sharkbite fittings will fit PVC, PEX, and COPPER. Push them on. Good luck! **Q: There is no hole for the pressure relief valve to go into. How do i install it?** A: The brass valve on the top with the lever on it is the pressure relief valve. Mine came with valve already installed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a life changer and a profound water conservation appliance *by C***A on April 22, 2021* It's earth day and appropriately so I decided to weigh in on the reviews.

Not cold water! *by R***R on January 14, 2024* Outstanding product and built with quality and performance. I was amazed how easy it was to install. Disconnect your hot water line to the sink faucet, then connect a line from the hot water line to the blue intake on the heater. Bring the faucet line over to the red output line and use teflon tape and do not over tighten using non compression lines. Put the unit on a waterproof tray and I seen many pictures of the pressure release valve and none used the existing water PVC tubing to run the pressure relief hose directly into the sink drain tubes. Easily purchased a (8” dishwasher branch baffled tailpiece) installed it directly to the sink drain with a plastic hose to the Ariston water heater pressure relief valve. Having knowledge of plumbing is very helpful in this installation. I never opened the installation manual. I did browse over the quick installation guide. If you feel this is not your forte then get someone with plumbing experience to help you. I give this a 5 star rating and the fact that when I turn on the the hot water, it is hot right away! No wasted water. ## Frequently Bought Together - Ariston Andris Mini Tank Electric Water Heater – Heating Solution for Under Sink, RV, and Compact Spaces, Smart Boost for Versatile Heating, Simple Installation, 120-Volt, 2.5 Gallon Capacity - SHURFLO (255-313) 1/2" Twist-On Pipe Strainer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/128836134-andris-2-5-gal-6-year-120-volt-point-use](https://www.desertcart.hr/products/128836134-andris-2-5-gal-6-year-120-volt-point-use) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
