Introduction
“But are they noisy?”
It’s one of the first questions many homeowners ask when they see an Air Source Heat Pump.
The simple answer is that modern systems are designed to operate quietly. However, the make, model, installation and position of the outdoor unit can all make a difference.
1. How Much Noise Do They Make?
An Air Source Heat Pump has a fan that draws air across the outdoor unit. Like any mechanical equipment, it makes some noise while operating.
Modern units are designed with noise reduction in mind, and the sound level is generally low when the system is correctly installed.
2. Where the Unit Is Positioned Matters
Good positioning can make a significant difference.
An experienced installer will consider the location of the outdoor unit, nearby windows and surrounding areas when planning the installation.
The aim is to provide good airflow while keeping the system as unobtrusive as possible.
3. What About at Night?
Heat pumps can operate for long periods because they provide steady, lower temperature heating rather than short bursts of high temperature heat.
A properly selected and installed system should operate within the relevant noise requirements, including those applying to residential properties.
