Why Boiler Academy
Stop Guessing. Start Diagnosing with Confidence.
Boiler faults can be confusing when engineers rely only on fault codes, guesswork, or theory. Boiler Academy helps engineers and apprentices build a clear diagnostic process they can apply to real jobs.
Follow a Clear Process
Use structured training and the F.L.A.M.E. Method™ to analyse boiler faults logically instead of replacing parts blindly.
Build Practical Confidence
Develop stronger confidence in diagnostics, servicing, controls, CP12 awareness and repair planning through online learning and London-based practical training.
Improve Real Job Decisions
Make better decisions on-site by understanding how boiler components, controls and heating systems work together.
Our Training Method
The F.L.A.M.E. Method™
A structured, repeatable five-step process to approach any boiler fault, eliminating guesswork, saving time, and increasing your diagnostic accuracy on every job.
F
Fault Identification
Identify the fault, symptoms, fault codes, safety concerns and system behaviour.
L
Logical Analysis
Analyse boiler sequence, controls, wiring signals and system logic before assumptions.
A
Assessment of Components
Test sensors, pumps, fans, valves, electrodes, PCBs, wiring and controls.
M
Methodical Repair Planning
Plan the safest, most logical and cost-effective repair based on evidence.
E
Execution & Testing
Carry out the repair, test operation, confirm safety and document findings clearly.
