Title: This is a life changer and a profound water conservation appliance
Review: It's earth day and appropriately so I decided to weigh in on the reviews. 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!!!

Title: You want hot water? Not cold water!
Review: 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.

Title: Buy the service valves!!
Review: Before it would take me 1.5mins to get hot water to my kitchen sink. I replaced the lines running into my kitchen from steel galvanized lines (due to the rust in the lines getting in my drinking water) to PEX B (the crimp kind of pex, not the expanding Pex A). In the process I decided it would be a good ideal to perhaps look into this type of setup instead of waiting the 1.5mins to get my hot water at the kitchen sink. I researched the amount of water my dishwasher would need and which unit would be sufficient for my application. I then removed BOTH steel lines into my kitchen and ran 1 cold water line. I then put a Tee in the cold water line in which 1 runs to my cold water faucet connection and the other runs into this unit. Then I plumbed my hot water off the heater to the fixtures via a 1/4 turn valve to pex B end.THIS IS BY FAR the best upgrade I have ever made to my home in a LONG time. Why didn't I do this sooner?! The 4 gallon version I got works wonderful for the dishwasher and it only needs 110v/120v of AC power. Since I ran the Tee on the cold water coming in, I should have ran 3/4" Pex B, but I can do that in the future (if needed).Notes of installation:1. The outlets on the heater cold and hot side are 1/2" so to run the service valves I had to buy a brass adaptor to convert to 3/4" (brass adapter I purchased, but would be better to use PVC between the different metals https://www.amazon.com/dp/B0823NKRX3?ref=ppx_pop_mob_ap_share2. BUY THESE SERVICE VALVES: HYDRO MASTER Tankless Water Heater Service Valve Kit with Pressure Relief Valve 3/4-Inch IPS Isolator Clean Brass https://a.co/d/6iY91JtI've saw TONS OF PEOPLE complaining they have to remove the tank to drain it, buy these valves and you won't have to do that! C'mon people!3. DO NOT plug this unit into the same plug-in under your sink as your dishwasher. The load is too much to run both and is a fire hazard!! I ran a dedicated 20amp circuit from my main panel to a GFCI plugin (required by code and good idea since it lives under the sink and water can make contact to it)! Do NOT skip this step! 12-2 Romex is rated for 20amp and assuming you are not running at 100' AND this is the only draw to the circuit, then you should be good to go.4. Remember to flush the heater 1-2 times a year using the above mentioned service ports. YouTube has plenty of videos on what you need.5. I hope this helps you to settle the debate on which one to buy, this or the Bosch one (that I passed on due to mixed reviews)6. A cheap $1.25 Dollar Tree holiday ham/turkey foil pan fits under it nicely
