Solar heating systems for domestic hot water. Code of practice for design and installation

Status : Current   Published : January 2015



What is this standard about?

In the wake of increased uptake for such systems to provide domestic hot water and the provision of UK Government subsidies, this standard explains how to design and install solar heating systems.

Who is this standard for?

  • Solar heating designers
  • Installers, suppliers and specifiers 

Why should you use this standard?

This revision updates the original 1989 standard, following recent technological developments and assessing existing best practice. It includes details of current test methods and terminology, plus important new safety guidance.

What’s changed since the last update?

The scope of the standard has been extended. The revised version includes a much wider range of buildings than just the single, family dwellings covered before. It also deals with the wider range of material types now on the market.

Along with specifications for high performance solar collectors, insulation and safety components, the new standard includes:

  • Financial and environmental information
  • Installation techniques to mitigate faulty systems
  • Methods for expansion vessel sizing
  • A new UK solar irradiation map
  • A reflectance radiation factor table
  • A method to assess bacterial risks
