Customer Questions & Answers

does this unit heat only on demand when water is flowing or all the time

Asked by: dsp54
This unit heats water in the tank as needed like a full-sized water heater.

What does 6-Year mean?

I purchased one of these and have gone through 2 heating elements and one thermostat so far. Is 6-yr maybe its expected life?
Asked by: Hank
6-Year refers to the tank life. So, basically, yes, that's the life of the unit.

Will this fit under the sink if I have a garbage disposal?

Asked by: jakkdogg
Assuming you are referring to the in-sink food waste disposal, and if you have a double sink, likely this water heater can fit on the wall behind, or the floor under the sink that doesn't have the disposal. Before buying any under-sink appliance, it is best to measure the free space and take a picture of the place you want to install it and consult your appliance department associate.

2.7 gal. 6-Year 1500-W 120-Volt Point-of-Use Mini Electric Water Heater is rated 4.4 out of 5 by 197.
Rated 4 out of 5 by from Thermostat only flaw We installed this unit under our bathroom sink which was at the opposite end of the house from our tankless hot water heater. Before installation it could take 2 minutes for hot water to reach the faucet. Installation was a breeze once the electrical was in and took literally 10 minutes. Only drawback is that there appears to be a big jump in temperature settings from one "notch" to another on the thermostat. One side of the notch is not hot enough and the other side is a bit warmer than we need. Can't comment on reliability but we have it hooked up to a timer as we only really need it on for an hour in the AM and an hour in the PM, saving money. Works great at the moment. Highly recommended.

Rated 5 out of 5 by from Great Point-of -use hot water heater I instaled the unit several weeks ago and it is great to have hot water right away. Before we would have to wait several minutes and a couple of gallons of water. By the time the hot water is used up in the unit under the sink, the hot water from the main heater is at the kitchen sink. The Point-of-use heater doesn't even turn on because the main hot water has filled the unit. I have had a Watt meter connected to the circuit since I installed the unit and my estimated monthly cost is only $1.10. I save more then that in the cost of the water saved. It was easy to install and I would recommend this unit.

Rated 5 out of 5 by from Completely satisfied This was a Christmas present to my wife, who was having to wait many long minutes for warm water to arrive at her bathroom sink, on the opposite end of the house from our on-demand main water heater. This small heater has been the perfect solution. It fits nicely under the sink. Drawing only 1500 watts meant that an existing 120 volt, 15 amp circuit was used for the installation. I was easily able to plumb it in myself, tapping into the cold water supply under the sink, and running the hot-water line from the water heater to both bathroom sinks. (See attached photo.) I plugged the electrical cord into a timer, heating the water only between 6 and 9 AM. The water heats up from a cold start in about 15 minutes. For our morning wash-up, we never use more than the 2.5 gallon capacity, and the remaining water stays warm well into the afternoon. We’ve used it now for a couple of weeks, and couldn’t be happier. Although I don’t expect it, just in case a leak should develop, I placed the heater in a pan and built a small, electronic water alarm that will alert me to any problem.

Rated 5 out of 5 by from This is the easy, cheapest solution to get instant hot water. There are many Rube Goldberg-ish designs to get instant hot water in rooms far from the main hot water heater, but they all have drawbacks–either high cost, complexity, or technical issues. This small, 2 1/2 gallon tank fits under a counter, is easily connected and uses house power–no electrician needed. Any average user can do the installation in 20 mins or less. I'm a graduate engineer and have evaluated other attempted solutions to this problem, and this is far away the cheapest, and safest answer. I love it!

Rated 5 out of 5 by from Easy to install. Fittings are a challenge but doable. There is no need for plumber. This water heater was very easy to install. Make sure you have reinforced backing if hanging on side wall of cabinet under sink. Flush heater before hooking to faucet.

Rated 3 out of 5 by from Leaking Tank and poor design This was a install done by a plumbing company and they installed this heater. It is not a bad heater but it's been 6 years now since the work was originally done and I'm just now installing my 3 replacement heater same model each time but always the same problem after 2 or 3 years LEAKING from the tank. I wish they made a drain on the bottom of the tank so when you change the element and rod 2 to 3 times a year it is faster and neater.

Rated 5 out of 5 by from Excellent solution for me! I have had this heater a couple of weeks now and I am very pleased. My master bathroom is quite a distance from my water heater and it has always taken several minutes to get hot water at the sink. It was not only an inconvenience but a waste of about 2 gallons waiting for hot water. It is installed under my sink vanity and takes up half my storage under there but it is worth it. Measure carefully. I had 1/4 inch leeway when I measured and it fit perfectly. The measurements provided on the Home Depot website are spot on. It requires a 120v outlet and uses 15 amps. You might have to install an outlet under the sink if there is no convenient way to power it. I drilled through the floor of the vanity and attached the unit to a dedicated 15 amp power strip which plugs into a GFI outlet next to the vanity. The only other thing on my 20 amp circuit are two Sonic toothbrushes, so no problems from that. The device is simple to operate. Set the thermostat and you are done. The box says easy one person installation. That is probably true for someone who is able to contort themselves under a small bathroom vanity and spend some time on their knees. There are two connections. I ran the hot water connector into the intake of the unit and then ran the output of the unit to the hot water faucet. When I say "I", I mean a plumber. I can do rudimentary plumbing but my knees and back make it difficult for me to work on the floor in small spaces. I set the unit inside a small cat litter box. No matter how good a water heater is, someday it is going to fail and if it leaks I didn't want 2.5 gallons of water leaking out onto the floor. Now we have instant hot water and wife loves it!

Rated 5 out of 5 by from Pretty good Easier to install than I expected, worked well immediately. Follow the instructions, no problem except it didn't make it clear if I needed to add a temp and pressure control. Took me a few readings before I found it was built in. Only dislike about the product: have to remove the screw cover (#1) to remove the screw to remove the cover (#2) so that I could remove the two screws to remove the cover (#3) to slightly increase the water temp setting. Each cover covered a cover, what the heck is that all about? Redundancy is a waste . . . I left the first two covers off for easier faster access in the future.
