GB29541-2013
The minimum allowable values of the energy efficiency and energy efficiency grades for heat pump water heaters
热泵热水机（器）能效限定值及能效等级
GB 29541-2013 is a current mandatory Chinese national standard for The minimum allowable values of the energy efficiency and energy efficiency grades for heat pump water heaters. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Oct 1, 2013.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to motor-driven, vapor-compression refrigeration cycle heat pump water heaters that use air as the heat source. Compliance with this standard is mandatory for all relevant manufacturers entering the Chinese market. It is important to note that this standard currently does not apply to water-source heat pump water heaters.
Technical requirements
The standard establishes a five-tier energy efficiency grading system for heat pump water heaters, where Grade 1 represents the highest efficiency and Grade 5 represents the minimum allowable limit. The grading is determined by the Coefficient of Performance (COP) and varies based on heating capacity, type (ordinary or low-temperature), and heating method (e.g., primary, circulating, or static heating). Products must meet the Grade 5 limit to be legally sold, while Grade 2 serves as the evaluating value for energy conservation. Additionally, the standard specifies strict tolerance requirements: the measured COP must not be less than 95% of the labeled value, and the measured heating power consumption must not exceed 110% of the labeled value.
Testing methods
Testing procedures are conducted in accordance with the referenced standards GB/T 23137-2008 (for household use) and GB/T 21362-2008 (for commercial and industrial use). The standard specifies that for products providing a water pump, the pump's energy consumption must be included in the total energy calculation. Manufacturers must ensure that hot water storage performance meets the corresponding requirements of the referenced standards.
FAQs
What products are regulated under GB 29541-2013?
It regulates motor-driven, air-source heat pump water heaters using a vapor-compression cycle. Water-source heat pumps are excluded from this standard.
What is the minimum energy efficiency requirement?
The minimum allowable value corresponds to Grade 5 in the standard's efficiency grading system. Products failing to meet this mandatory limit cannot be legally sold in China.
How are testing methods determined for these products?
Testing follows GB/T 23137-2008 for units with standard water tanks and GB/T 21362-2008 for those without, with specific rules for calculating water pump energy consumption.
