AIR SOURCE HEAT PUMP Well suited to urban environments


The Vitocal 200-A Pro from VIESSMANN is a compact and robust air source heat pump for residential and commercial applications. It comes in 32, 64, and 128kW outputs and can be cascaded up to 1024kW.


The heat pump provides both heating and active cooling and operates in bi- or monovalent modes. It features highly efficient scroll compressors and enhanced vapour injection technology, offering a high flow temperature of 65°C at -7°C. With a SCOP of 4.4, it uses non- flammable refrigerant R407C. The unit operates quietly with a total sound power level of 69.7 - 71.6 dB(A). Installation is faster, thanks to factory- installed operating and safety devices.


AUTOMATION STATION Flexibility and improved interoperability


SIEMENS has expanded its Desigo HVAC and building control system with the introduction of the PXC5.E24 controller. This new automation station enhances a system's capabilities by offering increased flexibility, improved interoperability, and easier installation. The PXC5.E24 controller features 24


onboard I/Os, which can be expanded to a total of 80 points on a single compact unit. Interoperability is a


key focus of the PXC5. E24 controller, with two RS485 ports enabling integration of Modbus data points via RTU and/ or the BACnet open communication protocol. It also includes an onboard KNX PL-Link for easy daisy- chain network extension, with M-Bus integration available soon. Quick installation and commissioning


is ensured through a simple and intuitive license-free ABT site engineering tool, supported by the ABT Go mobile app for smartphone connectivity. It can also


32


provide power for up to 4 extension I/O modules from the TXM I/O range, streamlining the installation process. Secure remote connectivity offers


the capability to monitor and make changes to the system off-site, reducing the potential number of site visits and therefore improving sustainability.


The feature-rich weather-compensated remote monitoring and control system, combined with a single refrigeration circuit across all models, means operation and maintenance are greatly simplified, too. “This is a very user-friendly heat


pump,” says product manager Hugh Jones. “It’s particularly suited to urban environments where space is at a premium, thanks to its low noise levels, compact size, and incombustible refrigerant. We’re anticipating strong sales from organisations such as schools and housing associations that need a system that’s efficient, reliable,


and easy to operate and maintain."■ www.viessmann.co.uk


The Shoebox NX heat pump from KENSA is a British-made ground source heat pump that offers a solution for decarbonising heating in a significant number of UK homes. It is designed to be compact and powerful, fitting into a cupboard and catering to various types of homes, including high-rise flats and terrace streets. The heat pump is presented as being five times more energy efficient than a gas boiler, making it a promising option for reducing carbon emissions. Kensa's solution incorporates


Networked Ground Source Heat Pumps, which aims to replicate the convenience and accessibility of gas networks, enabling the widespread adoption of heat pumps in the UK. This approach is expected to bring renewable heating and cooling to a wide range of homes, including both new builds and older structures.


Tamsin Lishman, Kensa CEO, says:


“This is a game-changing heat pump designed for the UK. Until now, achieving mass heat pump rollout has been a complex challenge, but with the launch of our Shoebox NX, we’ve engineered a small, high-performance heat pump that’s ready to replace gas as the main home heating choice. When combined with our Networked Ground Source Heat Pumps solution, it unlocks cosy homes in the winter and cooler homes in the summer for almost anyone, and at low costs to the


consumer." ■ www.kensaheatpumps.com


BLACK PHOTOVOLTAIC PANEL


Full black aesthetics for high-end rooftops


Vertex S+ 450W (NEG9R.25) is the name of TRINA SOLAR's new full black PV solar panel designed for high-end residential rooftops. It is aimed at meeting the demand for sustainable energy solutions that are not only efficient and reliable but also aesthetically pleasing.


Measuring 1762 x 1134mm and


weighing only 21kg, it incorporates advanced n-type i-TOPCon technology and has an output of 450W+ and efficiency of 22.5%. The NEG9R.25 utilises black cells,


frames, encapsulants, and thinner wires to achieve the full black aesthetic. Its high uniformity ensures integrity in building exterior design with minimal colour difference, enhancing the visual quality and aesthetic experience of solar energy.


The 1.6+1.6mm dual-glass structure


Alarms can be processed on site or remotely through the user’s wireless access to the controller. Security is a central feature of the design, with certificate handling and signed firmware to prevent cyber attacks from malware


and viruses.■ www.siemens.co.uk


is said to provide exceptional durability and resilience with a high resistance to scratches, breakage, impacts, salt spray, acids, alkalis, high temperature, and humidity. The module combines advanced n-type i-TOPCon and 210mm rectangular silicon wafer (210R) cell technologies, delivering a robust power output of up to 450W and an efficiency of 22.5%. Its compact size and lightweight design facilitates easy handling and installation on residential rooftops.


Trina says that over 25 years the


panel can yield up to 15.1% more energy than a p-type module. It comes with an extended product warranty of up to 25 years and a power warranty covering 30 years. Its ultra-low degradation rates are said to offer customers peace of mind, ensuring the sustained effectiveness


over many years.■ www.trinasolar.com
