Errata 1 - appended. Published 30/07/1986.
This Standard covers installation of systems of fixed orientation and inclination of up to 6 m2 collector area and 450 L storage capacity, capable of auxiliary heating and delivering potable water, but excluding space or pool heating.
This Standard sets out the requirements for the installation of domestic solar water heating systems incorporating auxiliary heating and intended to deliver water of potable quality. Systems covered are of fixed orientation and inclination having a collector area of not more than 6 m2 and a storage capacity of not more than 450 L. They may be either:
(a) systems with collector located remotely from container; or
(b) systems with collector and container close-coupled or integral.
The primary water circuit flow between collector and container may be by thermosiphon or forced circulation, and the auxiliary heating may be integral with, or remote from, the solar water heater. Where the collector is located remotely from the container either component may be supplied separately or both components may be supplied as a complementary system.
