Unica MAX is the name of a new hybrid enabled, hydrogen-ready gas condensing boiler from Vokèra by Riello. Available in a choice of combi and system models, the boiler features a corrosion-resistant stainless steel heat exchanger.
Designed to accept 20% hydrogen, the new Unica MAX will adapt to burn the methane-hydrogen blend if and when the local network makes the transition. The boilers have active combustion control (ACC) so they can adapt the air/gas mix according to the gas quality available.
The boiler can also be linked with an air source heat pump, with the system automatically switching between them depending on which will deliver the most energy efficient heating at the time.
At the heart of the new boiler is a colour LCD user interface. The full text menu-driven control enables both the installer and end user to quickly navigate through the boiler’s parameters and settings, including an optional embedded time clock to set on and off times. The display will also provide installers with full diagnostics for ease of service and maintenance.
