One solution is to get some antivibration feet or pads, or if you’re a particularly light sleeper, to install sound proofing around the system. Keep this in mind when you’re deciding where to fit the ground source heat pump – the vibrations can be a bother if you’re in a room adjacent to or above it. However, unlike a dishwasher, you may want to keep the heating on overnight if it’s a particularly cold evening. Furthermore, the main unit of sits inside your home, so your neighbours can rest easy. They also generally make less noise because there’s no fan component and the heat source is warmer, so there’s less strain on the compressor. In contrast, ground source heat pumps sound not dissimilar to a dishwasher. If your heat pump starts making more noise than usual, get in touch with the contractor who installed the heat pump. Most modern heat pumps are only audible from a few metres away, as in the video above. NB: there are a number of videos online of faulty heat pumps making a alarming racket, but don’t let this put you off. To put this into perspective, take a look at the table below: However, it’s down to your installer to ensure that the heat pump is below the noise pollution levels of Permitted Development rights. If the noise pollution is 42 decibels or more from the nearest neighbouring property, the installation would need planning permission. These newer models tend to be better designed, with thicker chassis and quieter fans. Most modern heat pumps are built in a way that give off as little noise as possible to avoid putting the customers through the hassle of applying for planning permission. The outdoor unit should be sited as far away from the neighbouring property as possible, and it’s also a good idea not to site the box directly beneath any windows. Noise pollution is calculated during the design stage of the heat pump installation to avoid disturbing your neighbours. This is down to the speed of the fan that draws warm air into the compressor (see how does a heat pump work). The volume of noise also depends on how much work the heat pump is doing – the greater the work load, the louder the heat pump will be. This video was filmed on an iPhone 7 at a distance of 1 – 3 metres.Īs you can probably tell, modern air source heat pumps shouldn’t make more than a low whirring sound providing they’re working properly. 3 oC, and the third is in colder conditions (December, -6 oC). The second is of a single Daikin unit at approx. In the first clip, 3 Vaillant air source heat pumps are all working simultaneously in a mild climate (approx. The clip above shows 3 different air source heat pump installations working at different speeds. What does an air source heat pump sound like? Fortunately, due to government regulations (see do you need planning permission for a heat pump), most modern air source heat pumps can work a lot quieter than older models. Overall, these innovations reduce noise by 7 or 8 dB, which is significant for heat pumps.Because heat pumps come in all shapes and sizes, the sound and volume of noise they make varies between models and manufacturers.
All of this helps to trap sound inside the unit. The product also includes an elevated compressor floating base plate, ensuring air-tight encapsulation around the compressor. The unit’s unique sound package includes an insulated blower and cabinet insulation, which dampen unwanted noise. The WQ comes equipped with Bosch-patented compressor encapsulation. The units unique sound package includes an insulated blower and cabinet insulation, which. Targeted the compressor with Bosch-patented noise insulation technology The WQ comes equipped with Bosch-patented compressor encapsulation.To frame this in lay terms for your customers, this is about 7 dB softer than the sound of ocean waves. When all is said and done, the lowest overall round rating for the WQ is 53 dB. Since the fan is offset, air can enter the blower much more freely. SV Model, resulting in decreased power consumption and sound. Highly efficient, the DEC Star® Blower runs at a lower RPM (revolutions-per-minute) but delivers the same amount of air as the preceding Upgraded the fan to the newest technology.To optimize sound performance in the small cabinet, Bosch engineers innovated the following:
