Employee at Mitsubishi Electric UK – Building Manufacturer-Level Engineering Expertise

Before founding Therma-Dynamics Ltd, Nathan Draper spent over six years working within Mitsubishi Electric Living Environmental Systems (LES), one of the world’s leading manufacturers of advanced heating and cooling technologies. This period played a fundamental role in shaping Nathan’s technical depth, diagnostic ability, and quality-driven approach that now defines his work today.

Working across both field engineering and manufacturing quality roles, Nathan developed an extensive understanding of air source heat pump systems, refrigeration technologies, and large-scale HVAC product quality — experience that now directly benefits every Therma-Dynamics customer.

Aftersales Technical Services Quality Engineer

October 2019 – August 2022

In this role, Nathan moved beyond field engineering into the manufacturing and technical quality environment, working closely with UK and international teams to maintain product standards and resolve complex technical issues.

He developed exceptional expertise across Mitsubishi Electric’s product range, including RAC, PAC, Lossnay ventilation, City Multi systems, domestic heating products, and chiller technologies. Responsibilities included analysing failed or incorrectly operating equipment, identifying root causes, and reporting technical findings directly to manufacturing and research teams.

Key areas of responsibility included:

• Advanced fault analysis and investigation into system performance issues
• Interpretation of warranty and test data to identify potential quality concerns
• Strategic planning and management of factory re-work programmes to ensure 100% accuracy and operational efficiency
• Coordination of multiple teams, including logistics, subcontract engineers, Japanese re-work specialists, and third-party suppliers
• Reporting technical findings through structured manufacturing reporting systems to support product improvements
• Producing detailed technical reports and monitoring data for manufacturing analysis
• Supporting customer-facing investigations and attending technical meetings to resolve complex issues
• Managing workshop compliance, annual asset audits, and health and safety responsibilities
• Supporting spare parts, warranty, and technical teams with specification changes and technical clarifications
• Developing strong cross-department relationships across sales, procurement, logistics, quality, and international teams

This role provided Nathan with a deep understanding of how HVAC products are designed, manufactured, tested, and improved — insight that is rarely gained outside of a manufacturer environment.

Aftersales Site Services Technical Heating Engineer (Residential Heating)

March 2016 – October 2019

Nathan began his journey with Mitsubishi Electric as a residential heating technical engineer, providing direct onsite support for air-to-water heat pump installations across the UK.

This position involved commissioning, system optimisation, diagnostics, and customer support — ensuring installations operated correctly and met manufacturer performance standards.

Key responsibilities included:

• Providing onsite technical support from initial service request through to full resolution
• Commissioning and assisted commissioning of air-to-water heat pump systems
• Supporting system design and application guidance
• Performing servicing and maintenance to manufacturer specifications
• Quoting and completing remedial works to improve system performance
• Acting as a key technical contact for subcontract engineering networks
• Delivering onsite and remote training to engineers and installers
• Producing detailed technical reports documenting system performance, modifications, and repairs

Through extensive field experience, Nathan developed strong troubleshooting skills and a deep understanding of real-world installation challenges — experience that remains central to the way Therma-Dynamics approaches customer systems today.

Experience That Sets Therma-Dynamics Apart

Working within Mitsubishi Electric provided a rare combination of practical engineering experience and manufacturing-level quality insight. Nathan gained a full understanding of how systems operate throughout their entire lifecycle — from design and installation to long-term performance and product improvement.

This experience now translates into:

• Highly accurate diagnostics and fault finding
• Manufacturer-level commissioning standards
• Deep product knowledge across multiple HVAC technologies
