Course Information
The Level 3 Low Temperature Heating & Hot Water (LTHHW) course is designed for heating engineers, plumbers and renewable energy installers who want to develop the knowledge and practical skills required to work with low temperature heating systems in modern domestic properties.
Delivered from Teach A Trade’s training centre in Telford, this course focuses on the principles, design and installation requirements of low temperature heating and hot water systems, which are becoming increasingly common as part of energy-efficient and low-carbon heating solutions.
As UK building standards continue to evolve, low temperature systems are now widely used in conjunction with heat pumps, underfloor heating and high-efficiency radiators. This course provides the essential understanding required to design, install and maintain these systems effectively.
The course combines theory-based learning with practical application to ensure learners understand system behaviour, efficiency principles and real-world installation requirements.
