Monitoring Solar Heating Systems: A Practical Handbook focuses on the CEC Performance Monitoring Group’s objective to draw conclusions on benefits of installing solar heating systems in different parts of the European Economic Community. This book notes that small numbers of domestic solar heating systems have been built and installed in Europe, both in private homes and, more often, in homes built as part of national research and development programs. To demonstrate the value of solar energy and to monitor the behavior and output of solar heating systems, performance monitoring systems have been installed to collect the relevant performance data. Various recommendations are made and mentioned in Chapter 2, while several materials have been drawn together to assist those without previous detailed experience in this field to gain insight into monitoring the solar heat systems; these discussions are included in Chapters 3 and 4. This text also covers the monitoring of solar assisted active space heating systems, solar assisted passive space heating systems, and solar assisted domestic hot water systems. This book is a useful reference for those involved in monitoring the solar heating systems, who consider their task in light of the experience of others.
