Requirements which need to be taken into account in the design of open-vented or sealed systems.

This Part of BS 6880 gives recommendations regarding the fundamental considerations and the design considerations which need to be taken into account in the design of low temperature hot water (see 1.2.1) heating systems of output greater than 45 kW, open vented or sealed. It is primarily intended for use by building owners, building managers, installers and associated professionals. It is not intended to serve as a detailed design guide (see foreword).

The recommendations recognize the need to optimize the use of energy, reduce hazards and minimize effects detrimental to the environment.

Solar heating is outside the scope of this code.
