This standard is intended to help with the design and installation of solar heating equipment for domestic hot water (DHW). First published in 1980, it has been substantially rewritten and updated by a dedicated team of solar industry specialists, including Narec Distributed Energy.
It is especially intended to cover “ad-hoc” systems which typically represent UK practice, where the solar collectors and storage components are chosen from several providers and assembled on site, rather than a complete assembly from one source. Guidance is provided on controls, solar storage volumes, predicted solar energy gains, legionella risk assessment and installation practices.
