BS ISO 13675:2013

This standard BS ISO 13675:2013 Heating systems in buildings. Method and design for calculation of the system energy performance. Combustion systems (boilers) is classified in these ICS categories:

• 91.140.10 Central heating systems
• 91.040.01 Buildings in general

This International Standard is the general standard on generation by combustion sub-systems (boilers) for oil, gas, coal and biomass burning.

It specifies the

• required inputs,

• calculation method, and

• resulting outputs

for space heating generation by combustion sub-systems (boilers) including control.

This International Standard is also intended for the case of generation for both domestic hot water production and space heating.
