The Fusion Round combines a boiling–water tap and mixer tap. It provides hot, cold and boiling water from a single tap with a double–walled, round spout. When combined with the COMBI and CUBE, it can also provide filtered chilled and filtered sparkling water.

The tap is manufactured with a child–proof double push–and–turn handle. In addition, the COMBI tank features a maximum temperature/pressure relief valve rated at 8 bar as a safety feature.

The COMBI tank operates at 230V with a wattage of 2200W and a stand–by power consumption of 10W*. The CUBE tank operates at 220–240 V with a wattage of 100 W and a standby consumption of 5 W*.

For the Fusion with COMBI, the minimum mains pressure is 200kPa (2 bar), with a recommended pressure of 200–400kPa (2–4 bar). For the CUBE, the minimum water pressure is 200kPa (2 bar) and the maximum water pressure is 400kPa (4 bar).

The COMBI tank uses a HiTAC® water filter (High Temperature Activated Carbon). The CUBE tank uses an HF + AC water filter.
