Reliable hot water heater tank
This is a highly-rated hot water tank made by InSinkErator. It is easily operated with a dial that allows you to easily set the temperature. Simple and effective and and easy DIY installation if you’re handy. I purchased this along with the InSinkErator instant hot water dispenser and they work very efficiently. You can hear the hot water tank warming the water but it is not for a long duration or very loud.

Great replacement just check your model number
This was a great replacement and was the exact same model. It was easy to change and is working so far just great. Love the convenience of having instant hot water, but unfortunately, these tanks are not a long-term item. Usually good for a few years sometimes longer. Appreciated the lower price.

Don't! Just dont.
Buyers beware! Insinkerator may make good garbage disposals, but our hot water dispenser only lasted six years. Warranty is only for three years. Apparently, we are lucky because other people in reviews said that they had to replace theirs every 4 to 5 years. Ours was leaking from the plastic- encased, welded-stainless steel water tank itself. The exterior is not sealed and had separated a bit. However, owners are instructed to never open the casing. Obviously they're faulty. (They're made in China.) It ruined my cabinet and probably ruined my hardwood floor underneath, that I can't see. We only decided to purchase it again because it's less expensive than to try a new brand whose faucet would fit the hole in our quartzite countertop. And we'll probably move before we need another one. Owners with hard water must descale the water tank every 3-6 months depending on usage, and it is ridiculously inconvenient and poorly designed to empty the tank and fill it with vinegar or descaling liquid. Either a syringe and funnel or part of a turkey baster and funnel needs to be used! The filters aren't affordable either, if you want to go that route. With all that said, it is convenient. But, it takes up the space of a large shoebox under your sink cabinet and is always plugged in for the heater. It's wasteful. My husband insisted on replacing it for his tea every night. Buy a tea kettle instead.

My favorite appliance!!
This purchase was a replacement for the same model that we've had for 8 years, when we remodeled our kitchen. This is an amazing product! I use it every day, multiple times a day. I begin by warming my cup while the coffee is brewing. It quickly cuts grease from dishes and makes any instant drink or oatmeal or soup in a snap. When I begin with this tap water, the wait for boiled water is cut short. Our original tank came with a filter but the plumber did not install it and we neglected to add it. There was never an odor and the flow rate did not seem impacted. We did install the filter this time and will regularly do so. When reading reviews and researching this type of product to replace, we did discover that it is common for them to begin leaking around year 7 or 8 due to the aluminum tank lining. This model is on the lower priced end (not lowest) but we have been very happy with it and the cost is worth every penny. It has 2 flow rates, which is convenient, and we never use enough at one time to run out of the near boiling water. You will occasionally hear the tank heating but it is not loud. The week without it convinced me that we will never be without it. I highly recommend!!

This hot water tank works great and heats water quickly and consistently. The stainless steel design feels durable, and the 2/3 gallon capacity is plenty for everyday use like tea, instant meals, or small cleaning tasks. Installation is fairly straightforward if you’re comfortable with basic plumbing, and once set up, it runs quietly and keeps the temperature steady. Unfortunately, I had to return mine because it arrived as an open-box unit, which I wasn’t expecting. I would have kept it otherwise, since the unit itself seems solid and performs well.

Replaced an earlier model that failed after 10 years. Hopefully this newer model will last longer.

Using this boiler in our coffee bar. It works great and looks great. Don’t put you finger under the hot water tap. When they advertise instant hot they are serious. I would recommend this product to anybody
