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
Hanstrom Ume 3-in-1
What we like
- WRAS Approved confirms UK water-regulation compliance
- Touchscreen sets temperature from 75°C to 98°C
- 7 finishes including matt black and brushed gold
- Trustpilot praises responsive UK customer service team
Watch out for
- 98°C max never delivers genuine 100°C boiling
- Boiler warranty is only 1 year (tap is 2 years)
- Trustpilot reports boiler failures shortly after warranty
- 2.4L tank limits back-to-back dispensing to 7 cups
