BS EN 304 discusses heating boilers. BS EN 304 applies to the determination of the performances of heating boilers and combi boilers fired by liquid fuels. The requirements for the heating performances are laid down in EN 303-1:2017 and EN 303-2:2017.
The requirements and the performance of testing for the sanitary hot water production of combi boilers are laid down in EN 303-6.
BS EN 304 on heating boilers is useful for:
Boilers shall be fire-resistant and safe to operate. They shall be made of non-combustible materials and shall be resistant to deformation and shall be such that they can withstand the stresses arising during normal operation, the burner and the boiler cannot become heated to create a hazard, dangerous accumulations of combustible gases (fuels mixed with air) in the combustion chamber and in the flues are prevented, and gases cannot leak from the boiler in dangerous quantities.
BS EN 304 you a test code to determine the performances of heating boilers and combi boilers fired by liquid fuels. The test code in BS EN 304 includes the requirements and recommendations for carrying out and evaluating the procedure for testing boilers and the details of the technical conditions under which the tests will be carried out. BS EN 304 helps you manufacture high-quality heating boilers and combi boilers.
