Basic Heating System & Boiler Fault Finding Course

Course Overview

The Basic Heating System & Boiler Fault Finding Course covers the required knowledge gas installers need to know to safely test for faults on central heating systems and boilers.

Fault finding training will equip candidates with the knowledge to identify a fault based on a boiler start-up sequence, understand and use manufacturers’ flow charts and wiring diagrams, plus use multimeters to test circuits, components and earth continuity, focusing on electrical safe isolation and safe working practices.

Course Benefits

The Basic Heating System & Boiler Fault Finding Course is ideal for gas central heating installers who need to install, maintain, repair and service central heating systems, as part of annual servicing or following a boiler breakdown, for example.

  • Electrical safety – anti-static precautions, electric shock hazards, etc.
  • Electrical Safe Isolation Procedure
  • Understand S & Y plan wiring systems (installation & faults)
  • Understand the operation of electric components within boiler circuits
  • Use of multimeters to analyse circuits
  • Locate a range of faults to components within the circuit
  • Fault find from a particular point in the boiler’s start up sequence
  • Principles of use and theory including safe working
  • Earth continuity testing
  • Testing for Polarity
  • Short circuit testing
  • Component testing

Entry Requirements

ETA Basic Heating System & Boiler Fault Finding Course is suitable for Gas Safe Registered engineers (either new engineers or those with minimal experience), who have completed the relevant ACS gas safety (CCN1) and central heating appliance (CENWAT) qualifications.


Best training I have had in 15 years of the industry. Very enjoyable and would always come back.
