What you need to know before you buy.

Yes, if you are comfortable with plumbing: it connects to your existing water supply (standard fittings), then the under-sink modules plug in. Full instructions and a video are included. There is, however, an electrical connection (230 V) and pressurised fittings: if in doubt, call the plumber of your choice.

Allow 1 h 30 to 2 h for a plumber (usually €100 to €180): removing the old tap, drilling if needed (Ø 35 mm), fixing, connections, under-sink modules, electrical connection and testing.

Yes, the boiling-water tank and the chiller run on 230 V. If you do not have one, an electrician can fit one in 30 minutes to 1 hour (allow €50 to €100).

Very likely: a standard Ø 35 mm hole, suitable for stainless steel, granite, quartz, laminate and solid wood. Only very thin worktops (under 20 mm) can be a problem. Send us a photo and we will reply within 24 hours.

You take it with you: removal takes about 1 hour. Fit a standard tap in the old home and reinstall your HYDRAL in the new one.

An insulated 3-litre tank under the sink keeps the water hot, up to 98 °C. It comes out immediately, with no waiting. The tank refills and reheats on its own (about 10 minutes for a full cycle).

Yes, if your water tastes of chlorine or limescale. The 5-stage filter (activated carbon + resin) removes chlorine, reduces limescale and traps particles. You have 30 days to judge for yourself at home.

The tap is the same. What changes is the water: Pure (€490) = filtered + boiling. Spark (€890) = filtered + sparkling + chilled. One (€990) = every kind of water.

The hot and cold water from the mixer works as normal. Boiling, chilled and sparkling water come back on their own when the power does.

Yes: they are standard 425 g cylinders, SodaStream-compatible. Choose ones certified for food use.

Direct sales with no resellers (who take 40 to 60 % margin), a lean company with no showroom or sales force. And a bet: earning over time on consumables rather than on a huge margin at the point of sale.

No. Every finish is the same price. Optional only: installation by the professional of your choice and a maintenance plan (€59 to €119 a year). The 5-year warranty is included.

Yes, in 3 or 4 interest-free instalments. For example: €490 = 4 × €122.50.

Roughly every 6 months for a household of 3–4 (more often for larger households, less often if you live alone). An indicator on the tap turns orange, then red: no need to keep count.

Once a year in hard-water areas. 30 minutes, either yourself (video tutorial) or by a partner technician, included in the Standard and Plus plans.

CO₂ cylinders, yes (standard size). Filters, no: they are designed for this tap (€35 each, or included in a plan).

Water at 98 °C scalds, just like water from a saucepan. That is why it has its own button, which you have to push and turn at the same time, with a child lock. It never comes out by accident.

No, the spout is insulated: you can touch it while boiling water is running.

Yes: CE and ACS (Attestation de Conformité Sanitaire, the drinking-water approval required in France). Food-grade materials, lead-free brass.

Manufacturing defects, electronic faults, leaks and module malfunctions. Not the normal wear of consumables (filters, CO₂) or damage caused by misuse or incorrect installation.

A reply within 24 working hours, remote diagnosis in most cases, and a part shipped within 48 hours if needed.
