Strengths and trade-offs
Franke Maris Water Hub 3-in-1 Mechanical
What we like
- The mechanical control needs a deliberate pull and turn, so a wiped worktop or a stray hand cannot start boiling water
- Pan-fill lock holds the flow open, which a spring-loaded control will not do
- A genuine 100°C rather than the 98°C most rivals settle for
- Around £140 less than the electronic version of the same system
Watch out for
- No filtered cold drinking water, and unlike the electronic model it cannot be upgraded to 4-in-1 later
- Two-year guarantee on tap, tank and filter housing, shorter than the Instante
- The Pro M cartridge runs about £80 a year and skipping it invalidates the guarantee
- Needs a 35 mm tap hole and a worktop no thicker than 50 mm
Franke Mythos Water Hub 6-in-1
What we like
- Six functions from one tap: boiling, chilled, ambient and sparkling plus hot and cold mains
- All-in-one under-sink unit houses boiler, chiller, CO2 bottle and filter
- 12-month filter interval with built-in RFID replacement reminder
- Pro M Connect filter adds ion-exchange limescale protection
Watch out for
- Sparkling water is held as 0.6 litres in the chiller and runs to 2.8 litres before it has to catch up, with a CO2 cylinder to replace
- Spout swivel is limited to 180 degrees
- Personalised settings need the Franke Home App
- Two-year warranty on tap, tank and filter housing
- 33 W of combined standby draw, the highest of any Franke tap in our library
