Plumbing & Heating Fault-Finding Handbook

Stop guessing your way through plumbing and heating faults.

The Plumbing & Heating Fault-Finding Handbook is a practical digital guide built for apprentices, trainee heating engineers, and new tradespeople who want to understand how to diagnose faults properly — not just replace parts and hope for the best.

Inside, you’ll learn how to approach common heating system problems including boiler faults, radiator issues, pressure loss, overpressure, circulation failures, hot water faults, thermostat problems, control wiring issues, and professional troubleshooting checklists.

This handbook helps you think more like an engineer by teaching you how to trace the system step by step: pressure, flow, heat, controls, and root cause.

Perfect for apprentices, improvers, and new plumbing & heating engineers who want a simple, practical reference they can study before jobs, after college, or while building confidence in the trade.

Turn fault-finding from guesswork into a system.
