Strengths and trade-offs
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)
Zip HydroTap G5 Celsius Arc (3-in-1)
What we like
- 0.2-micron MicroPurity filter removes dirt, lead, microplastics and 99.9% of cysts
- Cool-touch tap with boiling isolation and safety lock
- Boiling flow of 4 litres per minute
- Seven finishes and a 12-month filter interval
Watch out for
- Factory-set to 98°C rather than true 100°C boiling
- Needs both hot and cold supply at 1.7 bar minimum
- Three-year warranty (five on the tank)
