Strengths and trade-offs

Quooker Nordic Square Single Tap

What we like

  • Dedicated 100°C boiling tap that adds to an existing mixer
  • Squared spout matches handleless and modern kitchens
  • Child-safe handle: press twice and turn before boiling water flows

Watch out for

  • Boiling water only, so it does not replace your mixer tap
  • Two finishes: polished chrome or stainless steel
  • £1,050 for boiling alone is premium against a 3-in-1

Zip HydroTap Classic

What we like

  • Filtered boiling, chilled and sparkling from one tap
  • Touchscreen with PIN protection and energy-saving sleep modes
  • 0.2 micron NSF-certified filter included as standard
  • Largest UK engineer network for service and maintenance

Watch out for

  • £4,365 RRP is several times rival 4-in-1 prices
  • Installation around £520 extra on top of hardware
  • Ongoing CO2 canister costs for sparkling function
  • Designed primarily for commercial use, residential overkill
