| The 'Central Heating Combination Boilers - Fault Finding & Repair'
book covers combination boiler components background, construction and
design, operation, fault finding repair and servicing. Also, it includes
the use of manometers for standing, working and burner pressures, flue
gas analyser use , the correct use of a multi-meter for electrical tests
and component fault finding, gas pipe sizing, installation requirements
and of course fault finding logic tables designed to cover all
makes of combination boilers. There is much more besides. |
| The contents of this book have been written with heating engineers,
installers and students in mind but will also prove useful to others
interested in how combination boilers do what they do. |
The book has been written to help the reader understand:-
- System design and installation considerations and requirements.
- Design and operating principles of the component parts of
combination boilers.
- Control circuitry and therefore the system operating principles
of combination boilers.
- Possible fault reasons and repair of each of these component
parts.
|
| This will enable combi boiler installation, fault finding, repair
and servicing to be undertaken in a stepwise and logical fashion. |
