The outdoor unit generates two types of noise: the sound of the fan blowing air and the vibration from the compressor. We minimise noise disruption through careful placement and soundproofing measures, such as vibration-absorbing blocks and noise-reducing enclosures. On average, the outdoor unit of a hybrid heat pump produces 31-42 dB at 5 meters, similar to an old refrigerator or air conditioning unit.
Key Difference: An all-electric system runs continuously, even in summer when people are outside and can hear the unit. In contrast, a hybrid heat pump only operates during the colder months.
