New Zealand draft standards

The objective of this PAS is to provide advice and information on gas and liquid fuel boiler systems to enable an assessment of their performance and efficiency. Gas and liquid fuel boiler systems are common space-heating technologies used in facilities such as schools, hospitals, and commercial buildings, and also as part of industrial processes.

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.
