Best Hot Water Dispensers of 2025

"I've been using this for months, and I love it! Water is hot just as I want it, and I haven’t encountered any leaks or problems. Installation was simple, and it replaced my previous unit without any hassle."

"After using an instant hot water dispenser for years, I can’t imagine life without one! Hot water for tea and cooking is a game-changer. This new model fits perfectly over my farmer's sink, and I’m hopeful it lasts for many years."

"I had an Insinkerator before, and I loved it. So, when I moved, I ordered the same model again. Unfortunately, I received a push button instead of the handle I wanted. While I appreciate the convenience of instant hot water, the water isn’t as hot as my previous model, and sometimes the button sticks."

"I have used this product for 20 years across two homes. I just installed my fourth unit, which might sound bad, but we absolutely love it and use it daily. Based on my experience, these units tend to last about six years before they start acting up. If you’re not careful, you might even find it leaking under the cabinet, so I recommend keeping an eye on it after five years. Having instant boiling water for tea and coffee is fantastic, and I occasionally use it to clean pots and pans!"

"My old InSinkErator lasted four years before it stopped producing hot water. I did a lot of reading to ensure I got the right replacement. The installation was a breeze; I replaced it in under 10 minutes and even reused the original tubes without any leaks. However, it only lasted less than two years due to a broken heating element. Fortunately, customer service was excellent, and they sent me a new tank within five days under warranty. I’m giving a five-star review for their great service, not the product's reliability."

"This is, without a doubt, my favorite kitchen item. After 20 years, it finally gave out, and I was in a panic to replace it as soon as possible! Everyone should have an instant hot water InSinkErator, plus it even filters the water. I LOVE this product!"

"I installed this hot water dispenser a week ago, and I’m really happy with how the handle fits perfectly in my hand. The water flow is consistent and hot, and it looks great in my kitchen."

"I love our new hot water dispenser! It’s made it so easy to enjoy hot oatmeal for breakfast, tea throughout the day, and even hot cocoa at night. It’s such a great convenience for everyone in the house."

"I replaced my old unit with this one, and it was simple to install. I would have rated it five stars if it had come with all the necessary fittings. Still, it's been working great since the installation."

"After going through three Waste King heaters, I was thrilled to find this one that checks so many boxes. Super easy installation and the digital thermostat is a game changer. I love knowing the exact temperature of the water, which makes it so much easier than the trial-and-error of a dial. Plus, the safety feature for kids is a nice touch."

"I switched to this unit after my old tank failed. The digital readout is bright and very easy to see under the sink, and it works much quieter than my previous one. Installation was straightforward, although I did have to adjust the old mounting screws a bit."

"We missed having instant hot water when our previous dispenser broke. After installation, I was really pleased with how easy it is to adjust the water temperature. The plumber had a few challenges during the setup, but now it’s working great!"

"I had a Mountain Plumbing Little Gourmet that broke after a few years. Finally replaced it with the Ready Hot unit, and installation was a breeze! I don’t know why I waited so long—this one works great and was much cheaper!"

"I bought this replacement tank after my original was clogged from hard water. Installation took just 15 minutes, and I had 200-degree hot water ready in 5 minutes. Great product and great seller!"

"I received the product quickly, but it was missing connectors. After some delays, I finally got them, but the unit leaked. Thankfully, after contacting support, they sent a replacement that worked well, though it isn't pressurized. Now, I keep it cooler than I'd prefer, but overall, it has been functioning fine."

“I purchased this unit to replace an identical one that lasted 14 years. It performed well until it failed due to hard water scaling, and I was thrilled to find an exact replacement at a fair price.”

“This is my third unit in 10 years. They work well and are convenient, but I wish they lasted longer. The first leaked, the second didn’t heat, and the latest also stopped heating after a short time.”

“I bought this unit over 12 years ago and it held up great. We use it frequently for tea and cooking, and I appreciate the adjustable temperature and perfect tank size.”

"I found that having instant hot water makes tea in seconds and is always nice for cocoa, oatmeal, and other things. Installation was completed within a half hour. It's so easy!"

"After receiving an instant hot water dispenser as a gift about four years ago, I realized I used it more often than my dishwasher. However, I’ve never been more disappointed in this Insinkerator model. The handle fell apart yesterday, leaving the hot water running constantly. Not worth the $300+ I spent."

"As a contractor, I decided to purchase this product for the second time. It's a really good quality product. The installation is straightforward, and it works perfectly."

"I bought this system because my husband is British, and we drink a lot of tea. The InSinkErator HWT-F1000S Hot Water Tank and Filtration System has completely transformed our drinking water. Now, I can enjoy pure, filtered water right from the tap, which is a game-changer for me. I used to be picky about bottled water, but now I happily drink tap water!"

"After purchasing a home with an outdated system, I had to replace it. Thankfully, the installation of the new one was straightforward, and having perfectly heated water on-demand for tea and coffee has been a delightful addition to my kitchen. It really saves time, especially when warming baby bottles. I find this product to be well worth the price!"

"I switched from a Franke Little Butler to the InSinkErator, and I couldn't be happier. The temperature regulator on the heating unit allows me to control the output temperature easily. While I do hear it gurgling when the kitchen is quiet, it’s taken some adjustment. Overall, I’ve been using the system for six months, and it has performed admirably!"

"I bought this for a remodel and had it installed by a plumber. At first, it sputtered a bit, but once the air was out, it worked perfectly. I didn’t adjust the temperature setting, and it’s hot enough for tea. It heats water fast and dissolves broth paste quickly. I’ve read about sputtering issues, which might be due to high temperature settings. I’ve been using it for several months and it heats back up quickly after use. The spout delivers a steady stream, which I think is for safety. The faucet looks nice, and I’d definitely recommend this product."

"I’ve had a few instant hot water heaters fail on me, but the first one lasted 10 years and the second one 7. Perhaps the water quality is a factor since I have a filter in front of the unit. Even if it only lasts 5 years, the convenience is worth it. I use it not just for drinks but also for cleaning greasy pans. It melts bacon grease perfectly. If they could improve the internal plastic, I think these units would last even longer. I won’t have a kitchen without one!"

"Our plumber highly recommended this brand due to its great selection of designs and price ranges. I think it looks even cuter installed than in the pictures!"

"After my kitchen remodel, I wanted brushed gold fixtures. I ordered a Kohler faucet in brushed gold, and it looks great. The French gold matches perfectly, and I’m happy with how everything turned out!"

"Initially hesitant due to the price, I ended up purchasing this hot water dispenser. Once I got over the cost, I found it to be well-made and functional. I appreciate the variable pressure feature, although I have to be careful with splashes!"

"I had a plumber install this for my Reverse Osmosis filter. The instant hot water is fantastic for tea and coffee. I’m pleased with its performance and aesthetics!"
