Mastering commercial heating controls


Diving deep into the intricacies of commercial heating controls and how they shape the way we heat our built environment, Darran Smith, technical manager for heating manufacturer Alpha, provides a comprehensive overview of the revolutionary advancements in the industry


T


he UK government’s Heat and Buildings Strategy highlights the urgent need to transform the heating landscape. Aiming for


a Net Zero future by substantially reducing energy consumption in commercial and industrial buildings by 2050 is ambitious but crucial. This involves imposing stricter energy efficiency standards such as SBEM calculations and introducing performance- based energy ratings for larger buildings. Given that heating in commercial and public buildings contributes 18.2 MtCO2e to UK emissions, the drive towards smarter controls and energy- efficient measures has never been more significant. However, commercial heating controls can often appear daunting to the untrained eye. It’s no secret that many businesses resort to enlisting the expertise of electrical control specialists to oversee the intricate details of their heating systems. As the industry evolves, is it possible that this specialised skill set could be made more accessible? At the forefront of this evolution, our business has long been developing innovative systems to alleviate the common complications faced by many companies, bridging the gap between complexity and usability. Commercial controls are not only technologically advanced but compatible with a broad spectrum of market options, ensuring seamless integration and maintenance. While the controls for these boilers are undeniably more advanced than those of domestic counterparts, the art of mastering them is within reach for installers when armed with the right training – an area which we offer within our commercial training course. Central to the ARES Tec’s functionality is an


advanced microprocessor-based control system, encompassing the Boiler Control Module BCM. Concealed within a pneumatically operated lift-up panel, these controls ensure security and aesthetics go hand in hand. Success stories from installations at establishments such as Norwich City Council’s premises and the Leonardo Hotel in Glasgow attest to its prowess. The design, incorporating self- contained modules, ensures efficient heat transfer tailored to diverse building needs. Conversely, the ProTec NX series offers a diverse


range of wall-hung commercial boilers, with an emphasis on versatility. From OpenTherm controls to conventional ON/OFF switches or 0-10v input, the series is designed for every commercial scenario. Moreover, its ability to interlink up to eight units

showcases the boiler’s adaptability to complex demands. Features like weather compensation and internal building demand compensation come as standard. Yet, with all this advancement, there exists a simple truth: any heating equipment, no matter how advanced, is only as effective as its controls. For large commercial facilities, especially those managing multiple climate zones or using building automation systems, controls become paramount. However, a recurring issue plaguing many businesses is the overlooked maintenance schedules. The neglect of regular upkeep can quickly diminish a system’s effectiveness and lifespan. This is where installers can step in and help tackle this by raising awareness of this issue with customers and working to get those routine, annual visits scheduled. In conclusion, the trajectory of the heating industry is evolving towards a blend of advanced technology, user-friendly interfaces and a commitment to sustainability. As we navigate the complexities of this transition, the collective efforts of industry leaders and dedicated professionals
