Strengths and trade-offs
Franke Omni
What we like
- True 100°C confirmed in Trusted Reviews testing
- Built-in filter delivers filtered cold water without add-on
- Spout body stays cool even during prolonged dispensing
- 4.2L tank larger than most rivals under £1,200
Watch out for
- Filter cartridges cost roughly £50 every 6 months
- Owners report flow slowdown after 2 years in hard-water areas
- Heating tank replacement reported at around £400 out of warranty
- Low mains pressure (under 1.5 bar) causes noticeable dribble
Quooker Classic Fusion Square
What we like
- Period styling in a squared spout for Shaker and classic kitchens
- Patinated brass develops a genuine patina rather than a printed lacquer
- Same PRO3 tank and 100°C boil as the rest of the Fusion range
Watch out for
- 3-in-1 only: no filtered or chilled water without the CUBE upgrade
- Patinated brass needs an occasional beeswax wipe
- Fewer finishes than the standard Fusion (no gold, gunmetal or black)
