EN 14825 Seasonal COP Testing for Reversible Heat Pumps: Eurolabs Laboratory Testing Service

EN 14825 is a European Standard that specifies the method for determining the seasonal coefficient of performance (COP) of reversible heat pumps. The standard is published by the European Committee for Electrotechnical Standardization (CENELEC) and is widely adopted across Europe and other regions.

The legal and regulatory framework surrounding EN 14825 testing is governed by various national and international standards, including:

  • ISO 9170-1:2015 - Thermal performance of heat pumps and energy efficiency

  • EN 14511-2:2008 - Heating appliances - Part 2: Heat pumps for space heating only

  • TSE (Turkish Standard) 1147:2020 - Reversible air-to-air heat pumps

    • International standard development organizations, such as the International Organization for Standardization (ISO), play a crucial role in developing and maintaining standards. These organizations work collaboratively to ensure that standards are aligned and meet global needs.

    Standards evolve over time due to advances in technology, changes in consumer behavior, or new regulatory requirements. Eurolab stays up-to-date with these developments to ensure our testing services remain relevant and accurate.

    Some of the key standard numbers related to EN 14825 testing include:

  • ISO 9170-1:2015

  • EN 14511-2:2008

  • TSE 1147:2020

    • These standards specify the requirements for reversible heat pumps, including performance characteristics, safety features, and environmental considerations.

    EN 14825 testing is essential for manufacturers, regulatory bodies, and consumers to ensure that reversible heat pumps meet specific performance criteria. The consequences of not performing this test can include:
