Description (English):

This document specifies test conditions and test procedures for determining the performance characteristics of air source heat pump water heaters for hot water supply with electrically driven compressors with or without supplementary electric heater and connected to or including only one hot water storage tank. Hot water storage tanks that are connected in series or parallel and behave hydronically as one single tank are considered as one hot water storage tank. In the case of heat pump water heaters consisting of several parts with refrigerant or water connections, this document applies only to those designed and supplied as a complete package. NOTE This document is not applicable to testing procedures for simultaneous operation for hot water supply and space heating. "Simultaneous" means that hot water supply and space heating generation occur at the same time and may interact.

Abstract

Overview

ISO 19967-1:2019 specifies standardized test conditions and procedures for determining the performance of air‑source heat pump water heaters for hot water supply. It applies to units with electrically driven compressors, with or without a supplementary electric heater, and connected to (or including) a single hot water storage tank. The standard covers installation requirements, climatic and test‑room conditions, measurement methods and reporting - but it is not applicable to combined or simultaneous hot water and space‑heating tests.

Key topics and technical requirements

Scope and definitions: clear definitions for terms such as storage volume, reference hot water temperature, volume of mixed water at 40 °C, off‑peak products, and smart control.
Installation and test setup: requirements for test apparatus, uncertainties of measurement, test room for the outdoor heat exchanger (air‑source units), and procedures for multi‑part packaged units.
Settings and test conditions: prescribed settings for non‑ducted and ducted units (including external static pressure), plus general and additional test conditions.
Performance test sequence: staged test procedure covering stabilization (stage A), filling/storage (B), filling and heating up (C), standby power (D), water draw‑offs and COP calculation (E), and reference temperature/volume at 40 °C (F).
Energy metrics and corrections: determination of useful energy content, total energy consumption, Coefficient of Performance (COPHW), standby power input, fan/pump power corrections, and handling of off‑peak and smart control products (including the Smart Control Factor, SCF).
Load profiles and annexes: normative and informative annexes provide standard load profiles (Annex A), SCF determination (Annex B) and operating temperature range guidance (Annex C).
Reporting and marking: required test data to record and content for the test report, plus marking requirements for units.

Applications and who uses this standard

ISO 19967-1:2019 is designed for practical use by:

Manufacturers and product designers for product development and warranty claims.
Independent test laboratories and certification bodies to perform repeatable performance tests and generate comparable ratings.
Regulators and energy labeling programs that need consistent test data for efficiency claims and compliance.
Specifiers, procurement teams and installers who compare performance, COP and standby losses when selecting equipment for residential and light‑commercial hot water supply projects.
R&D teams assessing smart control benefits and off‑peak operation strategies.

Related standards

Part of the ISO 19967 series (other parts cover different heat pump water heater types and test aspects).
Developed by ISO/TC 86 (Refrigeration and air‑conditioning), in alignment with ISO/IEC directives for standardization.

Keywords: ISO 19967-1:2019, heat pump water heaters, testing and rating, performance testing, air source heat pump, COP, smart control, load profiles, standby power, hot water storage tank.
