At The Kitchen Sink

4N1 Aqua-System - Instant hot, filtered, and tap on demand.

Simple Kitchen Tasks Shouldn't be a Hassle

We get it. Kitchens aren't meant for jumping through hoops. Getting water that's filtered or hot enough for cooking and cleaning can be frustrating and time consuming.

Enough with the gallon jugs and heavy cases of water.

Are you tired of breaking your back and wasting money to avoid using tap water? Let's face it. No one wants to work that hard for filtered drinking water. Wouldn't it be nice to get rid of that bulky water dispenser or stop looking for ways to keep your bottled water out of sight?

You have better things to do than wait for boiling hot water.

Are you fed up running the faucet, waiting for the water to get hot, then moving it to the stove or microwave to bring it to the desired temperature? It shouldn't be that complicated.

People are tired of navigating cluttered countertops and doing extra work to get the water they need.

At AquaNuTech, we provide convenience on demand with an all-in-one faucet, so you can spend less time doubling your efforts and more time doing the things you love.

Raving Reviews


"Incredible asset in the kitchen! I didn’t truly realize how much I’d become addicted to the features of this faucet until we had it. The instant hot makes morning coffee and quick pasta making a breeze."

Emylee Williams

We love our 4N1 faucet and tank system! The faucet itself is a beautiful piece added to our kitchen with a multipurpose function that fits all our family needs! As parents we are always sanitizing our bottles, toys, etc. ever day with our 198 degree instant hot water. Under the sink, it is a very small tank taking up little room leaving lots of space. Thank you so much AquaNuTech, looking forward to future products!

“Install was super easy! Love having filtered water and hot water all from the same faucet!”

Tammie Waddel

“What an incredible company! When it came time to install they walked me through step by step on the phone and via text. They were so patient with me as I was determined to install without hiring a plumber. With their guided help I did just that! Now I have their amazing product with instant hot water and cold purified water all hooked up. Thank you Tim! I highly recommend this companyand their products!”

Liz Gantz

“We absolutely love this faucet. First off, the style of it is very sleek and modern and really compliments our kitchen. Having filtered water at the faucet is very handy.... but the best thing about it is that the instant hot water is extremely handy. If you are looking for a functional and stylish faucet look no further. AquaNuTech has been amazing to work with.”

Installation, Compatibility, Warranty & Returns

A standard 120v electrical outlet is required  under the sink. If possible, use a separate circuit dedicated to your Hot Tank. It is recommended that a separate circuit serving only your electronic instant hot water appliance be provided or use an outlet that can be turned on/off by a switch.

This electronic instant hot water appliance is equipped with a power supply cord with a power plug. To minimize possible shock hazard, the cord must be plugged into mating, ground-type outlet grounded in accordance with all national and local codes and ordinances. If a socket outlet is not available, it is the responsibility and obligation of the customer to have a properly grounded outlet installed by a qualified electrician.

Standard installation should be no more than an hour, depending on whether new install in new construction or install with existing sink, plumbing etc. already installed.

No, the faucet must be used with our tank as they work differently to conventional systems on market.

If local codes permit, the instant hot water Dispenser feed line should be connected to the hot and cold water supply line using an isolation valve, or another means for providing the hot and cold water to the Dispenser.

IMPORTANT: If local codes do not permit the use of isolation valves, special feed valves can be obtained from your local plumbing supply distributor. If the water is mixed with impurity, ironing chips, grains of sand, and so on, the pipes of the electronic instant hot water appliance and Dispenser will be blocked and will void the guarantee. 

Don't install the electronic instant hot water appliance outdoors or in a location that may fall below 32F, otherwise the pipes and the Dispenser and tank will be frozen. This will cause serious safety trouble, possible bodily injury, accidents, and damage. Should this happen, the guarantee will be void.

Do not wash the electronic instant hot water appliance with water directly. The installation environment should be ventilated, with protection from the direct sunshine.

When installing the electronic instant hot water appliance, provide approximately 10cm to 15cm (4 - 5 ½”) of air space on the sides of the unit for air circulation and approximately 2.5cm (1”) from the mounting wall.

The environment humidity should be in the range of 10% to 60%. Be sure there is no dew.
