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 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
