As the course focuses on digital heating design using smartphone apps and computer software, you will need a reasonable level of ICT skills. For example:

  • Smartphone operation and app usage
  • Web browser navigation
  • Laptop/computer use.

A solid understanding of English and Maths is also essential to succeed in this course.

To complete this course you will need access to a smartphone. The college has guest Wi-Fi, but you will may need a mobile data connection when working in more remote areas of the college campus.

Course Delivery

Concepts are first introduced through short PowerPoint presentations to explain the fundamental theories that underpin heating system design – including details on conducting long hand calculations. You will then reinforce the understanding of these fundamental principles by completing manual calculations before applying this concept directly with digital technologies. Smartphone apps will allow you to input data before a detailed report is produced on specialist computer-based software.


Assessments are usually open book. We actively encourage the use of technology, including smart phone apps and the internet, to assist you in passing the assessment.
