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
Qettle Signature Modern 4-in-1 (4L)
What we like
- 4-litre tank serves up to 8 cups in one go
- Marine-grade stainless steel tap, engineered in the UK
- Two-stage child safety: button and turn before boiling water flows
- Choice of round or square spout in stainless, PVD colour or etched finishes
Watch out for
- 17.5-minute initial heat-up and 10-minute recovery after a full tank
- Standard kit does not include a pressure reducing valve
- Two-year warranty
