Strengths and trade-offs
Fohen Focetti Pro 4-in-1
What we like
- 4-in-1 from one spout including filtered cold
- Digital touchscreen with five temperature presets
- WRAS and CE approved with a child-safe spring-lock
- Sells at £489, well below the £898 list price
Watch out for
- 98°C, not a true 100°C boil
- Needs an electrical socket under the sink
- Power draw not published by Fohen
- Some units now ship with a Hanström-branded boiler
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
