BS 8693:2025

Full Description

This British Standard gives recommendations for the design and installation of new build construction incorporating systems circulating water in sealed heating and cooling systems prior to their handover to developers.

This British standard gives recommendations for:
- the design and preparation of pipework and plant, laying the foundations for stable water conditions;
- the removal of construction related debris before the heat/cooling source is available;
- validation methods and records to accompany the handover of new systems; and
- good practices to promote the quality, longevity and efficiency essential for successful operation of the systems.

This British Standard is relevant to systems in an individual residential dwelling or within a commercial enterprise, residential development or indirectly connected to a district heating and cooling system. It applies to individual heating and cooling circuits in single or multiple residential premises with a maximum system volume of nominally less than 250 l. See more
