Do they make a noise? Yes. Do they make much noise? No.
The best way to get a feel for how much noise they make without actually hearing one is to compare it to things we’re familiar with:
- Breathing 10 decibels
- Whisper 20 decibels
- Bird song 40 decibels
- 8.5kW heat pump 42 decibels
- Vacuum cleaner 70 decibels
- Helicopter take off 100 decibels
So, as you can see an Air Source Heat Pump is just 2 more decibels than the dawn chorus, and about 30 decibels less than a vacuum cleaner. Which is the same difference between a vacuum cleaner and a helicopter taking off. Which we think you’ll agree with us, is a massive difference. They’re not silent, but they don’t make much noise. However, we’ll advise you on the best location to place the external unit for minimal noise disruption in your home, or your neighbours’ homes. Incidentally, it’s entirely possible that your existing boiler actually makes more noise than your heat pump will.
Still not sure? Well, we have a video of one in action here for you to hear for yourself. We’ll admit, it’s not the most exciting video you’ll ever see, and we’re sure it won’t be the most exciting thing you’ll ever listen to, but we hope that it will answer the question of how much noise an Air Source Heat pump makes.
