Reader Question: Are there any rules on the positioning of air-heat pumps in relation to property boundaries?
Heat pumps remain the government’s favourite option for energy renovation schemes, with ministers praising their efficiency and green credentials, especially when compared to the electric radiators which heat many French homes.
They are not without opponents, however. Many have questioned their price and longevity – as well as the noise they can make.
Indeed, noise rules are the main ones which can impact the positioning of heat pumps. A 2006 law states: “No noise should by its duration, its repetition, or its intensity disturb the tranquillity of a neighbourhood, or the health of people.”
Since 2022, there has been special mention of heat pumps, classified as producers of noise relating to industrial activity.
Problematic noise is defined as the difference between ambient noise (without the pump working), and the noise when it is working, with measurements taken from the edge of the property.
How many decibels is allowed for heat pumps?
Between the hours of 7:00 and 22:00, a difference of five decibels is allowed. After 22:00, this reduces to three decibels.
Professional installers with an RGE qualification can only install equipment that meets the new noise regulations. They often use insulated feet and special attachments to minimise vibration.
Where older equipment exceeds the noise rules, the first step after checking with a decibel meter is to try to negotiate with the property owner. If they are inside most of the time when the heat pump is working, they may have no idea how noisy it is outside.
Various kits involving acoustic baffles can be installed to reduce noise. Sometimes a higher, more solid wall between properties can also help.
If the owner refuses to act, your first call is the mairie, which is charged with handling noise complaints. If the mairie does nothing, you can go to law.
