Strengths and trade-offs
Franke Maris Water Hub 3-in-1 Electronic
What we like
- Can be upgraded to a 4-in-1 later with Franke's filtered water kit, which no other Franke boiling tap offers
- Timed dispense means you can walk away while a pan fills
- The widest finish range in the Franke boiling range, including copper and gold
- A genuine 100°C rather than the 98°C most rivals settle for
Watch out for
- No filtered cold water until you buy the upgrade kit, which is a separate purchase
- Two-year guarantee on tap, tank and filter housing, shorter than the Instante
- Around £140 more than the mechanical version for the same tank and the same filter
- The electronic control needs the tap to stay powered, where the mechanical one does not
Franke Minerva
What we like
- £899 RRP undercuts most 100°C branded competitors
- 4.7L tank capacity highest in the sub-£900 segment
- Genuine 100°C dispense matches premium models
- M-Box install system fits in under 30 minutes for a plumber
Watch out for
- Review Centre reports flow degradation within first year
- No built-in filter (scale build-up in hard-water areas)
- Customer support email-only, no engineer home visits
- Trustpilot mentions boiler failures near warranty expiry
