This report was written in cooperation with the Environment California Research & Policy Center and the Frontier Group in 2007.

The report starts with a summary of exactly what solar thermal systems do, how they can have a positive effect on natural gas consumption and stating that the renewed interest in solar hot water can be traced back to the energy crisis of the 1970s.

This is a template document used for inspections in solar water heating systems.

This template document was produced in the framework of the MED-ENEC Project (Energy Efficiency in the Construction Sector), an EU funded project promoting cooperation between EU and MEDA countries in energy efficiency.

This short inspection checklist includes different sections on general data about the system, visual inspection, testing and measurements, user opinion and action list.
