Bosch Commercial & Industrial have today announced a new certified training course developed in partnership with the LCL Awards, aimed at increasing the quality of Heat Interface Unit installations.
The two-day course held at the Worcester Training Academy looks to help prepare installers for the incoming Heat Network Technical Assurance Scheme (HNTAS) and has been developed with the recently published “MEHNA Heat Network Installer Training Guide” as its basis.
The course focuses on the practical elements of installation and commissioning of HIUs with defined test methods that will need to become second nature for installers working under HNTAS. It introduces installers to likely Acceptance Testing methods necessary during commissioning and shows how to save time by adopting sound installation practices from the outset.
Darren Danks, Head of Training at Worcester Bosch, said, “To ensure we were delivering the best possible experience for our customers, we ran a comprehensive pilot course to test the syllabus. The insights we gained were invaluable, and the hands-on format has already proven to bridge a vital knowledge gap.”
Phill Rowley, an attendee on the pilot course, added, “The practical side of the course was very good, offering a great chance to put into practice what is expected when commissioning a HIU. These types of courses are very important because they help improve industry skills, ensuring correct commissioning practices that directly protect and improve overall heat network efficiency"
For those working on the maintenance of HIUs, it includes practical fault-finding methods that cover both HIU and heat network related faults. Successful candidates will obtain an LCL certificate, helping to demonstrate the training requirements under HNTAS.
Pete Mills, Commercial Technical Operations Manager for Bosch Commercial & Industrial, commented, “We’ve purposefully designed our new course with the MEHNA guide in mind. By working through it, we will train installers to adopt best installation practices that align with the requirements of the TS1 standard developed for HNTAS.
“These skills are an essential part of getting heat networks right from the start and will support the boost in green jobs that the Government is planning for the heat network sector. We are committed to supporting the industry transition to a multi-tech heating future and pioneering this first-of-its-kind course is one of many steps we are taking to do so.”
Neil Ovenden, Operations Director at LCL Awards said, “Heat networks have a critical role to play in achieving Net Zero, but their success depends on having a skilled workforce capable of installing, commissioning and maintaining Heat Interface Units (HIUs). This pilot programme was a vital first step in creating the industry's first regulated HIU qualification, which we hope to launch by the end of July. We are delighted that LCL Awards, working alongside Worcester Bosch, has been able to lead this important development and help establish the standards needed to support the sector's future growth."
The first two courses start on the 21st July and 24th August. To find out more please contact the Worcester Bosch Training team via [email protected].
