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. Vokèra, through its parent company Riello Group, is a part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions.
Available in a choice of combi and system models, Unica MAX also features a leading-edge heat exchanger in corrosion-resistant stainless steel. Widely recognised for its strength and durability, stainless steel used for this key component can potentially increase the life of the appliance and result in less downtime due to maintenance.
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.
For homeowners looking to replace their boiler with a more energy efficient heating solution, Vokèra’s Unica MAX hybrid system ticks the right boxes. As a hybrid it 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.
The new Unica MAX has been conceived and developed by Vokèra 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 and yet still retain their technical filtering properties.
Designed for ease of installation in various domestic heating and hot water installations, the new Unica MAX range is available in two combi boiler models: 35C and 40C and a choice of 20S and 30S system boiler versions.
