NBN ISO 19967-2:2021

This document specifies test conditions and test procedures for determining the performance
characteristics of air source heat pump water heaters for space heating with electrically driven
compressors with or without supplementary heater. The purpose of this document is to rate the
performance of the heat pump water heaters for space heating with no operation of any supplementary
heater. In the case of heat pump water heaters for space heating consisting of several parts with
refrigerant or water connections, this document applies only to those designed and supplied as a
complete package.
NOTE Testing procedures for simultaneous operation for hot water supply and space heating are not treated
in this document. Simultaneous means that hot water supply and space heating generation occur at the same
time and can interact.
