Central Heating Wiring & Controls Book 3
Our very popular book is an excellent reference for you to use on central heating wiring.
The aim of this book is to make wiring more rewarding. It had been design to help you carry out installations and fault finding on control circuits by giving you all the information you need in a clear and logical manner.
We have worked closely with the technical departments to take their existing wiring diagrams and schematics and turn them intro full colour illustrations which are much easier to understand and use.
The most common control circuits in use in the UK are the three port (Mid Position) and two and three port zone circuits. This book therefore contains a greater number of diagrams for those circuits.
For many years electricians and heating engineers have commented that wiring heating controls is a difficult subject to learn. (This book is easy to follow).
They want to be able to wire and test these circuits with confidence but the existing diagrams are not always easy to follow.
This book is for all levels from basic to advance easy to follow.

Central Heating Fault Finding Book
Written by a breakdown engineer of 45 years, George Staszak is the man who started Mr Combi Training ‘Hands On’ fault finding and wiring course for over 20 years until retiring in September 2022.
If you are an engineer going to service or repair a boiler you take tools, spanners, screwdrivers etc do you tak a manual? No, don’t expect one to be there, problem.
Don’t waste time guessing or phoning a friend, this book has 99% of every fault known. Use the flow charts.
Don’t go to any boiler without this book, no manual? No problem!
In our Central Heating Writing & Controls Book you’ll find a vast array of information and diagrams.

Every year all gas boilers should be checked for safety and efficiency by a Register Gas Installer with Gas Safe, often not done because there are not enough of them.
If the boiler is still under guarantee which could be up to 12 years, this check is part of the T&Cs.
Our CO CO2 chart will show you how good or bad THE boiler is, the result could be do nothing, service or time to replace. Every gas installer should have this chart.
Easy to follow and accurate.
