The heat pump is tested and marked for the temperature condition it is intended to work at. The method is based on the calculation method in standard ENincluding domestic hot water production. Sound power 1451-2 measurements are performed at specified positions around the sound source and around a reference sound source, from which the sound power level can be calculated.

The pressure difference between the two compartments of the calorimeter room shall not be greater than 1,25 Pa. Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. The marking also includes heat pumps intended for pool heating. The test involves two draw offs of half the volume of the storage tank, together with a single tapping to determine the maximum quantity of useable hot water and the reference hot water temperature.

Air-to-air, air-to-water and liquid-to-water heat pumps can be tested for approval for P-marking. The data from the test are used to calculate the system seasonal performance factor.
