What changes in your kitchen.
No more bottled water
Chilled, filtered water straight from the tap, so nobody lugs packs home from the supermarket or keeps bottles crowding the fridge.
One tap, not three gadgets
The kettle, the filter jug and the sparkling machine all retire. The kitchen keeps one beautiful tap and gets its worktop back.
Tea at the speed of the tap
Near-boiling water on demand for tea, coffee and cooking, with a safety lock so it cannot be dispensed by accident. No waiting on a kettle.
Fitted and cared for
We install and commission it, then keep it serviced with planned filter changes under Comprehensive Maintenance. One number if anything needs attention.
One tap, four things it pours.
Every RoyalFlow is configured to the waters you actually want. Boiling and chilled is the popular home pairing; sparkling makes it three.
Boiling
Near-boiling for tea, coffee and cooking, safety-locked so little hands cannot dispense it.
Chilled
Cold filtered water on demand, so the fridge stops doubling as a bottle store.
Sparkling
Carbonated filtered water from the same tap, without the machine on the counter or the cylinders in the cupboard.
Ambient
Room-temperature filtered water for drinking, jugs and cooking.
Compact under the sink, quiet about it.
Home installations run on the S102U under-counter unit, sized for a standard kitchen cupboard and serving households of up to 8 people. It chills, heats and carbonates out of sight, with built-in carbon filtration and UV as standard on every unit; on the worktop there is only the tap and a small drip tray.
