Review, 26 Dec. 2009
I wanted a book on CH systems (and the corresponding Hot water system) which specifically covered how the electrical components were interconnected and how they interfaced with each other. This book was very informative in providing both wiring diagrams and explaining how each component was activated and how it activated the next component. It has various chapters on Valves, Pumps, Boilers, Radiators, Control Systems,Hot water and heating circuits etc. It gives clear explanations of how various parts of the system work such as 2 and 3 port valves, frost thermostats, boilers and variants that you might expect to find. This is not a book which will teach you how to fix a leaking tap, in addition it is not one of those glossy DIY manuals. This book is focused on central heating systems and goes into great depth, not a general plumbing DIY manual.
Prior to reading the book I did not have a clue how my system worked or what the mess of pipe work did- now it all makes sense. By chance the actuator on a 2 port CH diverter valve failed last week (day before Xmas eve!)- and I was able to identify the fault, buy a new actuator and replace it. Prior to reading the book I would have frozen to death over Xmas as I did not even know what a 2 port diverter v/v was.
Could not have asked for more really.
