Carrier will be investing $16 million over the next two years to build an R&D Center of Excellence focused on residential and light commercial heating, air conditioning and domestic water systems located in Villasanta (MB), Italy. The goal is to expand the offering and strengthen the development of environmentally sustainable and innovative solutions, primarily heat pumps, hydrogen-ready boilers and IoT systems.
The investment will strengthen Carrier’s R&D capabilities and responds to a rapid increase in the demand for air-to-water heat pumps, efficient and sustainable solutions, as well as IoT systems and is linked to the acceleration of the roadmap outlined by the European Union’s Green Deal.
The project includes the construction of a new facility in Villasanta to house a laboratory and offices by the end of 2023.
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.

Vokèra by Riello has launched the all new Vision Plus condensing boiler range. Vision Plus adds to the features and benefits of its predecessor – including new stainless steel heat exchanger technology on selected models – to offer high flexibility in performance and installation for a wide variety of domestic applications. Vokèra, through its parent company Riello Group, is a part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.
The new range includes a choice of seven boilers: four combination boilers with outputs of 25 – 40kW and three system boilers with outputs of 20 – 30kW, all with a standard seven-year warranty. Featuring a click-fit flue system for easy installation across the range, and combination models with a universal pipe connection layout, the new Vision Plus is a great choice for installers and homeowners alike.
Vision Plus combines Vokèra’s extensive knowledge of boiler design and performance in an innovative, installer-friendly range that offers Class A energy efficiency in accordance with the Energy Related Product (ErP) Directive. All models are feature-packed to deliver energy-saving comfort and long-term reliability and have the OpenTherm controls protocol embedded.
As a further innovation, the 35kW and 40kW combination boilers and all three system boilers in the Vision Plus range feature a new, optimised radial stainless steel heat exchanger, which enables a wide modulation ratio of 1:8 for optimum operating efficiency and flexibility. This means that the Vision Plus 40C combi, for example, can modulate down to 4.9kW and the 35C down to just 4.4kW. This ensures that boiler cycling is reduced even when the central heating load is minimal. Ideal for larger homes, the 40C delivers an excellent domestic hot water rate (DHW) of 16.4 litres per minute at ΔT 35 C, while the 35C has an equally impressive DHW rate of 14.2 litres per minute at ΔT 35 C.
The 25C and 30C combination models use a proven aluminium heat exchanger, offering high thermal conductivity and combining the benefits of a lightweight, compact design. These models have small installation footprints and the rear flue option makes it easy to fit these compact appliances into small spaces, such as kitchen cupboards. They are also lightweight for easy handling and transportation.
All Vision Plus combination boilers have a built-in filling loop and include an embedded seven-day time clock with three modes of operation and back-lit LCD display for energy-saving comfort and control of heating times throughout the week. The universal pipe connection layout on all combination models also makes it easier when replacing another boiler with Vision Plus.
The system heat-only Vision Plus boilers can provide central heating, be matched with Vokèra AquaFlow unvented cylinders to provide domestic hot water storage, and be connected to any existing S-Plan or Y-Plan system. A wide modulation ratio ensures flexibility and efficiency and, thanks to the Modbus protocol, the entire Vision Plus range is designed to be ‘hybrid ready’ for integration into low carbon heating system designs. For further flexibility, all system models boast a built-in relay, which allows for easy integration with zone valves.
Flexibility is fast becoming a primary focus for many of today’s commercial condensing boiler installations. Martin Fletcher of Vokèra by Riello explores how commercial boiler manufacturers are addressing this need with advanced engineering solutions that combine heating innovation with a wide choice of accessories to create one product with almost limitless configurations.
As anyone involved in the heating industry knows, commercial boilers have changed significantly over the past few decades. These changes are due, primarily, to the introduction of gas condensing technology, which offers significantly greater efficiencies compared with non-condensing products. Typically, commercial boilers were big, floor standing units with a large footprint and in many cases they were sectional products that had to be assembled on site, involving considerable time and labour.
Needless to say modern commercial boilers have come a long way since those early models. Nowadays most appliances tend to be designed with heat engines and burners combined in a single box that can be wall-mounted (or floor mounted on a frame). This takes up a fraction of the footprint of the old sectional boiler and, thanks to condensing technology and associated innovations, modern boilers are able to offer much higher outputs for their size compared with the old non-condensing units.
But what has been the main driving force behind these changes? I believe the answer to that question is two-fold: the boiler manufacturers and legislation. Alongside a commitment to continuous product improvement and efficiency by leading boiler manufacturers like Riello Group, the heating industry has been the focus of increasingly stringent regulations to reduce carbon emissions. The urgent need to address climate change has been the motivation for many of the innovative technologies aimed at making our buildings more energy efficient. Given that commercial HVAC systems account for a high proportion of a building’s energy consumption it’s not surprising that boiler technology is among these innovations.
In recent decades the advancements in boiler design, together with regulations to increase energy efficiency in both the domestic and commercial heating markets, have driven the market towards smaller, more high-powered appliances. For example, a two-boiler cascade in our new Condexa Pro range offers around 250kW in a small footprint when compared with the larger footprint of older floor-standing units with a similar output. However, that’s not to say that there isn’t still a market for high-power, floor-standing appliances for certain applications and many manufacturers, including Riello Group, continue to produce them: the key difference is that now there is a choice.
From a boiler manufacturer’s point of view it is important to be able to offer solutions that fit the myriad requirements of different commercial projects, both new build and refurbishment. At Vokèra by Riello we believe the concept of system flexibility, or what we describe as ‘one product, multiple configurations’ holds the key to meeting the diverse needs of this demanding sector. Indeed, we know from our extensive experience of working with commercial specifiers and installers that the challenges and permutations they encounter are virtually endless, from single standalone and multiple cascade configurations to all the different ventilation, zoning and control requirements.
An installation in, say, a school may call for external boilers in order to free up internal space for an extra classroom or storage facility. Also, although plant room size is not generally an issue, there are occasions where boiler dimensions are a critical factor because of restricted space or access, so the option of a smaller system that doesn’t compromise output is perfect. Different projects will also have different flue gas exhaust requirements – a factor which has been addressed in the development of our new Condexa Pro boilers. Whilst the range is configured for open-flue configurations optional ‘room-sealed’ kits are available that enable each appliance to be re-configured for room-sealed applications. A versatile flue solution, including standard, twin-pipe and concentric is one of the key aspects of system flexibility and not only expands siting possibilities but can be a huge factor when terminating flue gases safely whilst also taking in to consideration suitable ventilation.
Of course, offering this level of flexibility and such a wide range of accessories could be daunting for even the most experienced heating professional. That’s why we believe this approach must come with expert support, if required, from the manufacturer to help customers build different configurations and guide them through the choice of components to meet their particular project specification.
Modularity and control
Modularity is at the heart of the new flexible commercial boiler concept as it enables a number of output sizes to be combined to achieve the required output. Being modular also means greater ease of access to the boiler’s various component parts when it comes to servicing. With a truly modular system units can be combined in multi-cascade configurations and in linear or back-to-back cascade applications. In addition, today’s more sophisticated control technology can play a major part in monitoring and managing the operation of a cascade at optimum efficiency in relation to demand. In fact, having this high level of integrated control means that in some cases an expensive Building Management System may not even be necessary. In addition to these benefits, the latest integrated logic-control (as used in our new Condexa Pro boiler range) enables a ‘managing’ and ‘dependant’ operation, allowing for the interchangeability of modules and for individual units to be isolated for routine servicing without disrupting continuity of operation.
Looking to the future, we believe flexibility will remain an important consideration in commercial boiler specification, alongside enhanced efficiency and lower emissions in the continuing quest for cleaner, greener heating. Whilst condensing technology already offers high efficiencies and ultra-low NOx emissions, further advancements in technology will enable the next generation of boilers to become even more efficient. We have already seen tighter emissions control with the recent introduction of NOx Class 6, where Class 5 had previously been the standard. This reflects the ongoing drive to improve air quality and achieve climate change targets. As a leading manufacturer of heating solutions, we will continue to only develop and market products that comply with the latest legislation and as the regulatory goalposts move, as no doubt they will, we shall have the foresight and flexibility to change with them.
