The task was to subjectively listen to and measure the sound pressure levels of two heat pumps, in the same configurations in a semi-detached building. The two dwellings and all installations and lengths are mirror images. The difference is in the manufacturers and pump types, but for the given conditions in the measurements and specifications were comparable.
Both installations were carried out by Krzysztof Nikisz of Ecointegrator. He also prepared both pumps for testing.
I invite you to watch the video on the Youtube channel #izziiinstalacje #Pojedynek pomp ciepła!! NOKAUT w pierwszej rundzie??
To sum up what is in the video I would joke that the sound from the iZZiFAST pump is suitable for listening to before falling asleep 💚 because the sound of the fan is balanced, subdued and above all quiet.
