DR SNZ PAS 5312:2021 Gas and liquid fuel boiler systems
This publicly available specification (PAS) provides advice and information on gas and liquid fuel boiler systems used primarily in space-heating applications that provide hot water between 30°C and 100°C. This broadly encompasses systems between 40 kW and 2 MW. Much of the guidance provided assumes that the gas or liquid fuel boiler system will be used to heat hot water but, where applicable, the general advice provided is also valid for other applications such as industrial process heat.
