Wilson Energy Launches New Range of HIUs


I


ntegrated heating, metering, pre-payment and billing & bureau specialist WilSon Energy has launched its own range of Heat Interface Units (HIUs), suitable for


any heat network in residential homes and commercial developments. After several months working with Europe’s leading heating


engineering groups, WilSon has developed a high quality, low maintenance range of HIUs for the UK market offering a versatile, cost effective and energy efficient solution. The WilSon HIU W1 to W6 deliver a range of electric


twin plate, single plate, mechanical twin plate and hybrid HIU options, ideal for heat pump applications and suitable for new build or refurbishment projects, as well as heat network upgrades. Andy Wilkinson, CEO at WilSon Energy, said: “Designed


by experienced engineers with simplicity of installation and servicing in mind, WilSon’s new range of HIUs are easy to install and configure. They can connect to any type of meter through a MBus or Modbus open communication connection, providing easy access to data for meter readings, remote diagnostics and data analytics. Following BESA testing, we’re also really pleased that the units offer the highest energy efficiency performance in the market by VWART (Volume Weighted Average Return Temperature).” While simple to install with an optional pipe-conversion kit for any connection top/bottom configuration


and easy to set up, the WilSon HIU range also has some sophisticated features. Removable panels provide easy access into the HIU for maintenance and servicing and a Legionella flush prompt signals when the system is first set up or been inactive for a long period. Each unit is available with a range of covers and colours including black EPP, black EPP with white gloss front and white steel. Andy continues, “Remote access to the unit via the cloud means that heat network performance and


efficiency can be monitored and managed off-site with the delivery of real time information. What also sets the HIUs apart from others on the market, is that it can be set up to bring back 45 parameters for data analysis and troubleshooting, where other market leading HIUs only offer 9 parameters. All settings can also be securely adjusted remotely” The WilSon W1 is the first in the range to fully launch this autumn. This compact electronic, twin


plate heat interface unit is an indirect transfer unit for supplying heat. It fulfils two purposes at once: decentralised DHW heating based on the instantaneous water heating principle and decentralised indirect heat distribution in residential units. The WilSon HIU range is in stock and available to order for next day delivery from WilSon Energy. For more information about WilSon Energy’s services, visit our website.

Ovia Adds Anti-Glare Inceptor Hi-Bloc to its Industrial Highbay Range


A


n innovative addition to its industrial Highbay range, the Inceptor Hi-Bloc is


designed with both performance and versatility in mind. The Hi-Bloc is a CCT and power switchable linear Highbay, aimed to deliver highperformance illumination across environments that demand both precision and intensity—such as warehouses, factories, gymnasiums, and other large-scale, high-ceilinged industrial or commercial spaces. The launch of the Hi-Bloc marks


a strategic expansion of Ovia’s Highbay offering, with a deliberate shift toward an aesthetically unique yet highly practical product. The distinctive diffuser design not only elevates the visual profile of the fitting, but also supports superior glare control, with a UGR rating of ≤22. This reduction in glare significantly enhances the working environment in high-demand industrial settings, promoting comfort, focus, and safety. What also sets the Hi-Bloc apart is its distinct linear design, engineered specifically to improve lighting


efficiency in tight aisles and long rectangular spaces. The Hi-Bloc's rectangular form and narrow 72° beam angle focus light directly where it is needed most, ensuring optimal visibility in every corner of the space. From installation to operation, the Hi-Bloc is engineered for versatility and ease of use. The CCT and


power switch is intuitively positioned behind an IP65 threaded cap for easy access. Each unit includes two mounting hooks as standard, allowing for chain mounting (chains not included but compatible with existing setups), and features an integrated spirit level to ensure perfect alignment during installation. For added flexibility, a mounting bracket accessory is available, catering to a wide range of installation requirements. For further enhanced lighting control, the programmable remote allows full customisation of lighting,


with the ability to adjust PIR detection range and sensitivity, daylight thresholds, standby periods, and hold times, allowing for easy fine-tune performance for maximum efficiency, comfort, and flexibility across different environments. In addition, the Hi-Bloc integrates seamlessly with Ovia’s 5W 3 Hour Maintained IP65 Emergency Pack, just

Siemens adopts traffic light approach for newly designed range of IAQ sensors


A


complete redesign of the Siemens range of room sensors has indoor air quality (IAQ) as


a central focus, with the introduction of a traffic light system to enable any issues to be identified at a glance. Many IAQ sensors indicate the


levels of CO2 parts per million for a given environment. However, without information regarding what constitutes an ideal level in terms of air quality, this can be effectively meaningless. This has brought the introduction of a simple yet powerful tool to address this challenge: CO2 traffic light sensors, with a green, amber or red light indicating the respective good to bad levels of air quality in real time. Ron Purcell is a Product Manager


with Siemens Buildings and comments – “there are numerous applications in which this will be a real benefit in ensuring that air quality is optimised. Taking education as an example, there have been many studies which highlight how poor air quality can have a detrimental impact on the ability to learn. Research suggests that keeping CO2 levels below 1,000ppm can increase productivity by between 2-18%. However, it is unreasonable to expect a teacher to have an in-depth understanding or the time to constantly monitor CO2 levels, whereas a simple red light provides an immediate alert that the air quality is poor and that it is time to open a window or improve the air circulation through the building’s BMS. This visual cue empowers building occupants to take control of their environment without needing technical expertise. It also fosters awareness and behavioural change, encouraging proactive ventilation habits that improve IAQ without relying solely on automated systems. Hospitals and care homes are just another two examples of where this approach will allow a much quicker intervention to ensure that air quality is maintained and does not adversely affect the health of patients or residents.” The new visual indicators are just one feature in the redesign of the next generation of Siemens room sensors which include temperature, relative humidity, CO2 and TVOC (total volatile organic compound) sensors. Available in black and white options for all models, the new range offers improved aesthetics, touch screens for easier measurement changes, mobile apps for ease of configuration and higher sensor accuracies.
