Vokèra by Riello has launched the Unica MAX, its hybrid enabled, 20% hydrogen-ready gas condensing boiler range to meet the current integration needs of various energy sources, including gas, electricity and renewables.
Available in a choice of combi and system models, Unica MAX also features a leading-edge heat exchanger in corrosion-resistant stainless steel.
In the journey to net zero emissions, hydrogen-ready boilers are considered key to enabling the conversion of existing gas distribution networks from natural gas to low-carbon hydrogen. Designed to accept 20% hydrogen, the new Unica MAX will adapt to burn the methane-hydrogen blend 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.
At the heart of Unica MAX 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 program the heating on and off times as desired. The display will also provide installers with excellent diagnostics.
The Unica MAX hybrid system combines the familiarity of a traditional boiler with the renewable energy of an air source heat pump; the system automatically switches between them depending on which will deliver the best energy efficiency at the time. Integration of a domestic hot water (DHW) tank can be carried out from solar (if any) and/or from a heat pump. The boiler carries out the possible heat integration based on the set temperature. For ambient heating, the boiler prioritises the use of the heat pump depending on outdoor temperature and the temperature required by the system.
Developed to deliver warmth, efficiency and long-term reliability, with high DHW performances and up to 94% seasonal efficiency for space heating, this latest addition to the range offers a new air filter featuring filter mats that can be washed yet still retain their technical filtering properties.
The Unica MAX range is available in two combi models, 35C and 40C, and a choice of 20S and 30S system versions.
