  • Working very well so far.
Style: Manual Dial
So far so good. I had a different brand that kept dying on me after about 2 months. I literally replaced it with the same brand 5 times. This machine was cheaper, easy to install and so far is working perfectly. I pray it lasts.

  • Works well!
Style: Manual Dial
Worked perfectly! I bought my own faucet to match a particular style, and this ended up being pretty easy to install. The tank takes around 30 min to heat up when you first install it, so don’t be discouraged if it takes a little while to generate hot water. After that, it’ll be near-instant and perfectly hot! I’m super happy that I was able to buy a tank without a faucet since I had a specific design style in mind. ... show more

  • Tank leak
Style: Manual Dial
This tank is from a previous installation Ready Hot 41-RH-300-F560-BN. The tank started leaking as shown in the pictures. The tank is stainless steel and the bracket holding the plastic water inlet is aluminum. The two dissimilar metals have created galvanic corrosion and resulted in the leak. My new unit RH-200-SS has the same dissimilar metal and will eventually cause corrosion also. The first unit was installed in August, 2020 so it is 3 years old. I love this unit and will continue to purchase them but I am looking for a way to repair the unit. Has anyone repaired or attempted to repair the leak? How do I get the corroded bracket out of the tank in order to repair it? It would seem a plastic washer and perhaps epoxy glue would be a good repair. I hope someone can offer a good solution. ... show more

  • Dangerous
Style: Manual Dial
I had the digital version of this for 5 years and it worked great (then it started leaking from the bottom). I decided to replace it with the less expensive version, because I figured I could use a thermometer to adjust the temperature. But this one doesn't regulate the temperature well, and it keeps spraying boiling water all over when I'm not using it. I keep trying to turn down the temperature so that it's now in the black, but it won't stop randomly spewing boiling water - so it is dangerous. I am ordering the digital one again. Unfortunately I spent so long trying to fix it that it is now too late to return it. This one will be going to the scrap yard. ... show more

  • Works well came dented although the outside box was OK
Style: Manual Dial
It came with a dent in it, we just bought the tank and it was working, but Amazon did me right by cutting 20% off the price or something like that. It was interesting that it was ended because the box itself was fine. It was almost like they got a return from somebody put it in a new box and shipped it to me. It works and they cut me a deal on the price so who can complain ... show more

  • Great quality and customer service
Style: Manual Dial
This is my second purchase of this item, and it has been a stalwart of reliability. The first one lasted over 10 years. I had a problem with a small broken piece when it arrived but their customer service is excellent and they replaced it quickly. Would highly recommend.

  • Definitly the way to go
Style: Manual Dial
We've had this for a while now. It's great -- hot water on demand and plenty of it. It's much quieter than our old one. Unlike before, we only have the temperature turned up about 3/4 of the way because that's all that's needed to brew tea, make ramen noodles and instant soups and cereal.

  • A good under sink water heater
Style: Manual Dial
Got it today and replaced the old one after 10 years. Installing was easy since the connection was same as before. Hope this one also last along.
