Strengths and trade-offs

Grohe Red Duo L-Size

What we like

  • Boiling, filtered and a full hot-and-cold mixer in one tap, no second tap hole
  • Large 5.5L boiling reserve (7L total) on the L-size boiler
  • Child-safe touch-button dispensing with ChildLock as standard
  • Sells around £1,625 at UK specialists, far below the £2,578 list price

Watch out for

  • 99°C dispense, not a true 100°C boil (despite Grohe’s "100°C" marketing)
  • At around £1,625 it is still a premium tap, though far below its £2,578 list
  • BWT filter must be changed yearly or every ~600L, an ongoing cost
  • Standard guarantee is 2 years (3 only with registration), shorter than InSinkErator or Franke

Quooker Nordic Round Twintaps

What we like

  • Boiling tap and matching mixer supplied as one coordinated set
  • Dedicated boiling spout, so no risk of an accidental boiling dispense from the mixer
  • Choice of PRO3, COMBI or COMBI+ tank

Watch out for

  • Needs worktop space and two tap holes
  • Two finishes: polished chrome or stainless steel
  • Steeper than a single 3-in-1 that covers the same functions
