  • It works and was easy to install.
Style: 12 Gallon
I do wish that there was a temperature control as usually the temperature is not hot enough that I think it should be after you have ran the hot water for a little while walked away and come back then the water is definitely hotter, but I still have a pot Water in for my dishes and you definitely don’t need to add cold water to your shower. Hot water works fine. Fit perfectly under the counter of my RV and has plenty of water for all my RV needs ... show more

  • Good heater
Style: 19 Gallon
Great heater for 120 volts and just for a kitchen or one bathroom. Only complaint is it doesn’t have a light to know if it’s heating and doesn’t have a thermometer, so I upgraded the heater with those

  • Works perfectly
Style: 12 Gallon
I ordered this to replace a 4-gallon Point of Use water heater for our cabin in Maine. I like that even though it is 3 times the size of the other, it still is a 110-volt heater. I had an early issue with it and called the manufacturer and it was resolved right away. Terrific customer service and a really great hot water heater. ... show more

  • Good quality water heater at a value price.
Style: 19 Gallon
I replaced a 49.5 year-old 17-Gal water heater in my park model mobile home with the Ariston 19 Gal. I got a water heater install kit at the local Ace Hardware for the connections. It was a bit of a fit struggle, but it turned out quite well. The water is nice and hot at the 150° setting, and I verified the water temp with a thermometer at 152°. I'm all in at under $500 installed so that's a great value, fortunately I was able to do the plumbing and electrical connections with the help of my son. ... show more

  • Might Save Lots of Money on My Hot Water Bill
Style: 19 Gallon
I purchased and Installed this 20 gallon electric hot water as they advertised for POU for Point of use hot water. Currently the price of Natural Gas just increased from 60 cents to 90 cents per CCF. But, my electric bill is price locked for 3/4 cent for the next 6 months and then increases to .80 cents. Currently Electricity cost less than natural gas. So I installed this and followed all the specs. Output from my NG Hot water heater to this POU HW Heater. The literature states that the heater needs about a 4 hour recovery time. I am actually watching a 2 hour recovery time. The water is set at 135 degrees and was delivering almost scalding hot water. For a shower you need about 15 gallons of hot water and the tank which is actually a boiler and stores 19 to 20 gallons of hot water. After a couple days I shut down the Natural Gas Hot Water Heater and am currently using only this Ariston POU 19 Electric Hot Water heater as my only source for Hot Water. Works Great for 2 people. Due to the current Natural Gas Price increase and the not as aggressive Electricity Price increases this item appears to be a great bargain for hot water. Takes about one and half hours to install using copper and copper fitting and sweating the pipes and I installed one shark bite ball valve. Could be installed faster using all Shark Bite. For the wire I installed a 20 amp circuit breaker into the Main and installed a 20 amp extension cord that is under 25 feet. I will probably change the circuit to hot wire. Makes a Great Hot Shower. ... show more

  • Leaked, doesn't come with required hardware, poorly designed.
Style: 6 Gallon
The tank has hot/cold ports on both the top and side so you can configure to meet your needs. Comes from the factory with plugs in the side ports, which you have to move to the top if you want to use the side ports. After connecting my hoses to the top ports and filling the tank, the factory-plugged cold port on the side started leaking. I removed the leaking plug and added some teflon tape, but it still leaked. This product does not come with protruding threaded hot and cold plugs/threaded pipes, you have to supply your own. To wire the tank, I used a cable/clamp connector in the provided hole to thread the wire though. Unfortunately, with the cable connector in place on the provided panel, the panel does not fit back in place because part of the cable connector hits the metal frame of the tank. Overall, really poorly designed tank. Returned it. ... show more

  • Perfect for my Camper
Style: 12 Gallon
I'm very pleased with this, only takes about 20 min. to heat up totally, since it is for my camper Rambler that is stable on my property I did not need propane, and it does not have to be on all the time since I use it periodically.
