Drinking-water tap · ZipZip HydroTap G5 Celsius Arc
One tap for everything: instant filtered boiling water plus unfiltered hot and cold for washing up, from a curved tap over an under-bench unit, for up to 60 users.
About the Zip HydroTap G5 Celsius Arc
The Zip HydroTap G5 Celsius Arc is the one-tap answer for sites that need instant filtered boiling water but not chilled or sparkling. It gives filtered boiling water plus ordinary unfiltered hot and cold water for washing up, so the drinking tap and the sink mixer are the same fitting. Zip's sheet says that if you need just one tap for everything, this is the one. The command centre that does the work sits under the bench.
Zip's UK sheet lists it as boiling plus hot and cold for up to 60 users. Because one tap does both jobs, it needs only a single 35 mm hole in the worktop. Sovereign Water supplies, fits and services it under a maintenance plan. For the wider range, see the Zip range.

Typical applications
Who the Zip HydroTap G5 Celsius Arc is for
- Anyone who wants one tap on the sink instead of a mixer plus a boiling-water tap.
- Workplaces, which is where Zip's own sheet aims it, with boiling water safety locks and a cool-to-touch tap.
- Sites that do not need chilled or sparkling water, because this model does not make either.
- Teams of up to 60 people, which is the figure on the sheet.
- Sites that already have a hot and a cold supply at the sink, because this model needs both.
How the Zip HydroTap G5 Celsius Arc works
Drinking water goes through Zip MicroPurity 0.2 micron filtration into the command centre, which heats it and sends it to the tap. Zip says the filter takes out dirt, lead, cysts and microplastics, and describes it as 25 times more effective than a standard water filter jug. Boiling water is factory set to 98 °C for smooth, non-sputtering delivery, and Power-Pulse holds stored boiling water within 0.2 °C of the set temperature.
The hot and cold water for washing up is separate from the filtered boiling water, and Zip describes it as unfiltered. The unit needs both a cold and a hot supply connected, unlike the cold-only HydroTaps. Zip lists boiling water safety locks and a cool-to-touch tap, and the tap rotates through 180°.
Zip's sheet gives a flow rate of 4 l/min. If you are weighing it against a kettle or bottled supply, see our comparison of an instant boiling water tap and a kettle.
Which one should you choose?
The Celsius Arc is the one to pick if you want a single tap on the sink and only need boiling water as well as hot and cold. If you also want chilled and sparkling water, look at the Celsius Plus All-in-One.
Zip HydroTap G5 Celsius Arc
You want one tap for filtered boiling water and hot and cold for washing up, for up to 60 people, with a single 35 mm worktop hole.
Zip HydroTap G5 Celsius Plus All-in-One
You also want chilled and sparkling water from the same tap as the hot and cold.
Zip HydroTap G5 Classic Plus
You want a plain drinking-water tap next to your existing sink mixer, including a boiling-only model for up to 100 users.
Zip HydroTap G5 Cube Plus
You want boiling and chilled water (or sparkling too) from a squared-spout tap, and are happy to keep a separate mixer.
Installation and servicing
The tap goes through one 35 mm hole in the worktop and the command centre sits in the cabinet below. Zip's installation notes say installation must be done by a qualified person following national and local regulations. You need mains electrical and drinking water connections plus waste water drainage, all within 1 metre of the product, and because this model also gives hot and cold water, a hot supply as well as a cold one.
The cabinet needs discreet cut-outs for ventilation. Some stone worktops may need a specialist cutting service. Zip recommends a scale filtration kit in a hard water area, and lists a limescale filter kit as an accessory. The drawing above shows a clearance envelope 280 mm wide and 535 mm high, with a 50 mm gap on either side and an optional limescale filter alongside. Zip notes on the drawing that hoses are not shown to scale.
Sovereign Water installs and commissions the unit and services it under a maintenance plan. The datasheet does not give a service interval, so we set one with you at survey. The survey is chargeable and is credited back if you go ahead.
Zip HydroTap G5 Celsius Arc questions answered
What does the Zip HydroTap G5 Celsius Arc dispense?
Instant filtered boiling water, plus ordinary unfiltered hot and cold water for washing up, all from one tap. It does not make chilled or sparkling water.
Does it replace my kitchen tap?
Yes, that is the idea. One tap does the boiling water and the hot and cold for washing up. It needs a 35 mm worktop hole, and both a hot and a cold supply connected.
How many people does it suit?
Zip's sheet rates it for up to 60 users.
How many cups an hour does it give?
Zip's specification table lists 190 boiling cups an hour. The product name on the same sheet says 160. We confirm which figure applies to your model at survey.
How hot is the boiling water, and is it safe?
Boiling water is factory set to 98 °C. Zip lists boiling water safety locks and a cool-to-touch tap. As with any boiling tap, supervision matters where children or vulnerable users are present.
Is the hot and cold water filtered?
No. Zip describes the filtered water as the boiling water, and the hot and cold water for washing up as unfiltered.
What does it need to be installed?
A cold and a hot water supply at 1.7 to 5 bar, mains power, and waste water drainage, all within 1 metre of the unit. The cabinet needs ventilation cut-outs, and a qualified person must install it. The sheet gives 1.8 kW at 230 V but does not state the plug rating, so we confirm the power arrangement at survey.

Zip's UK datasheet lists an appliance warranty of 24 months plus an additional 36 months on the boiling tank.

Yes. We supply, install and service it under a maintenance plan. The survey is chargeable and is credited back if you go ahead.

Across most of southern and eastern England, mains water is very hard. Rain filtering through chalk and limestone dissolves calcium and magnesium, and that scale coats heating elements, so we size every system to your supply and your equipment.
