Undersink Water Chiller
Qettle Undersink Water Chiller
Chilled drinking water at 4°C from the filter system you already have. A stainless steel undersink unit that plumbs in between your filter and your drinking tap, so the shelf of bottles and the jug in the fridge door can both go. Fits a Qettle, and fits most mains pressure filter systems too.
What it actually is
This is a chiller, not a filter and not a tap. It has no cartridge of its own and it does not clean your water. It sits in the cupboard under the sink, takes water that your filter system has already cleaned, cools it to 4°C and sends it on to your drinking tap.
So it is an upgrade to a filter system, not a replacement for one. If you already have filtered drinking water at the sink, this is how you make it cold.
What it works with
Qettle taps. It is built for them. It sits beside a 2 litre or 4 litre Qettle boiler tank in a standard 600 mm base unit, and it retrofits to an existing Qettle without changing the tap.
Most mains pressure filter systems. The inlet connects to your filter outlet and the outlet connects to your tap, with connectors supplied for both 1/4 inch and 3/8 inch tubing. That covers the great majority of under sink carbon and sediment filter systems feeding a dedicated drinking tap.
Not reverse osmosis. The chiller needs at least 1.5 bar at its inlet. Water leaving an RO membrane is at far less than that, whether the system is tank fed or direct flow, so an RO system cannot drive this unit. If you have RO and you want chilled water, talk to us rather than ordering this.
Key features
- Chilled to 4°C. Fridge temperature, from the tap, with no waiting and nothing to refill. The exact temperature varies a little with how warm your cupboard runs.
- 1.2 litres on tap, 9 litres an hour. A jug and a half of properly cold water available at any moment, and if you empty it the tank is back up to temperature in about 15 minutes.
- Goes in between what you already have. Filter outlet in, tap inlet out. No new tap, no new hole in the worktop, no change to how your tap looks or works.
- Fits beside a Qettle boiler tank. Designed to share a standard 600 mm base unit with a 2 litre or 4 litre tank, so one cupboard holds both.
- Stainless steel construction. CE approved, and built to sit in a warm kitchen cupboard for years.
- Gets your fridge back. No bottles on the shelf, no filter jug in the door, no ice trays. For most kitchens that is a whole shelf returned to food.
Worth understanding before you buy
On a Qettle, the chilled water has its own channel on the tap. You keep boiling, you keep filtered, and chilled is added alongside them.
On a dedicated single drinking tap, the chiller goes inline, which means everything that tap gives you is now chilled. That is what most people want from a drinking tap. It also means the 1.2 litre tank is your cold reserve for all of it, so if you fill a two litre jug in one go the last of it will come through at room temperature while the tank catches up.

The cupboard has to breathe
A chiller works by moving heat out of the water and into the air around it. Shut inside a sealed cupboard it has nowhere to put that heat, and it will struggle to reach temperature and work harder than it should.
Qettle specify three or four ventilation holes drilled through the back of the cabinet, a grille in the kick space, or both, along with 75 mm of clear air on every side of the unit. This is not optional and it is the difference between a chiller that holds 4°C and one that does not.
Check these before you order
- A filter system already feeding a drinking tap, running on mains pressure rather than reverse osmosis
- Mains pressure between 1.5 and 5 bar, measured at a quiet time of day. Above 5 bar a pressure reducing valve is required
- Space for a unit 370 mm high by 180 mm wide by 320 mm deep, plus 75 mm clear on all sides
- A ventilated cabinet, or a cabinet you are willing to have ventilated
- A socket under the sink for the chiller, separate from anything else already plugged in down there
- A level surface for the unit to stand upright on
Supply only or supply and fit
Supply only. The chiller shipped to you to fit yourself or hand to your own plumber. The inlet connects to the filter outlet and the outlet to the tap with the push fits provided, so a competent plumber will not find it difficult, but the ventilation and the pressure check are both on you.
Supply and fit. Our technicians install it across Leinster, onto a Qettle or onto whatever filter system you already have. We plumb it in, sort the ventilation, check your pressure, flush it through and leave it chilling. Please note that we do not carry out electrical work, so a compliant socket needs to be in place before we arrive.
Frequently asked questions
Do I need a Qettle tap for this?
No. It is made by Qettle and designed around their taps, but the inlet simply connects to a filter outlet and the outlet to a tap inlet, with connectors supplied for 1/4 inch and 3/8 inch tubing. Any mains pressure filter system feeding a drinking tap can take it.
Can I put it on my reverse osmosis system?
No. The chiller needs 1.5 bar minimum at its inlet, and water coming off an RO membrane is well below that on both tank fed and direct flow systems. It will not fill or chill properly. If you have RO and want cold water, get in touch and we will tell you what your options are instead of selling you something that will not work.
Does it filter the water as well?
No, and that is the main thing to understand about it. There is no cartridge inside it. It cools water that has already been filtered, so you need a filter system for it to sit behind.
Can it be added to a system I already have?
Yes, that is what it is built for. It retrofits without changing the tap or the worktop, on a Qettle or on a standard filter system.
Will everything from my tap be cold?
On a Qettle, no. Chilled gets its own channel and you keep boiling and filtered as they were. On a dedicated single drinking tap, yes, because the chiller sits inline and everything passes through it.
Will it fit in the same cupboard as a Qettle boiler tank?
In a standard 600 mm base unit, yes, alongside either the 2 litre or the 4 litre tank. What usually catches people out is not the width but the ventilation and the 75 mm of clearance, so measure for those too.
Does it need its own socket?
Yes. It draws 170 W at 230 V, which is a light load, but it needs a socket of its own rather than sharing with anything else under the sink.
What if I run it dry?
You keep getting filtered water, just not chilled. The tank refills immediately and is back down to temperature in about 15 minutes. From completely cold, after installation or a holiday, allow around 20 minutes.
Are there filters to replace in the chiller?
No. The only cartridges in the system are the ones in your filter, on their usual schedule. Qettle do recommend an annual look over the unit to make sure the ventilation has not been blocked up by whatever else ends up in that cupboard.
Not sure whether it suits your setup?
Email us at info@nuaqua.ie and tell us what filter system you have. It takes us a minute to tell you whether this will work on it.
Make the water you already filter cold
4°C drinking water from your existing tap, and a fridge shelf back. Stainless steel build with a 2-year warranty.
