Risks associated with auxiliary heating: essential precautions to take

As winter approaches, with temperatures dropping and snow potentially appearing in some regions, it is crucial to ensure your safety and that of your loved ones. Portable heaters, while practical, pose significant risks, both to health and home safety. This article aims to shed light on the potential dangers associated with these heating devices, as well as the essential precautions to implement to ensure safe use. We will discuss not only the risks related to cold on our health but also those specifically associated with the use of portable heaters, providing practical advice, sustainable solutions, and information on the necessary equipment for this winter 2025.

The dangers of cold on health

The cold can have severe consequences on our body, especially when temperatures drop below zero. Children and the elderly, in particular, are especially vulnerable. Pathologies related to extreme temperatures are numerous. We will explore these various types of risks associated with the cold.

Pathologies caused by cold

Diseases directly linked to cold can be severe: frostbite and hypothermia are obvious examples. Hypothermia occurs when the body's temperature drops below 35°C and can cause serious injuries or even lead to death. Unfortunately, every year, hundreds of people suffer from these afflictions. Those already suffering from pre-existing conditions, such as cardiovascular and respiratory diseases, face an increased risk during intense cold.

• Frostbite: skin lesions that can lead to amputations if left untreated.

• Hypothermia: a reduction in body temperature that can have fatal effects.

• Worsening of pre-existing conditions: high blood pressure or respiratory issues.

Increased risks during winter

During winter, studies have shown that cold can increase the risk of cardiovascular mortality. For example, a British study found that a 1°C decrease in ambient temperature could increase the risk of myocardial infarction by 2%. Those most exposed are often elderly individuals with coronary artery disease.

Complications due to inappropriate measures

The cold, coupled with inappropriate behaviors, can lead to other risks. The improper use of portable heaters, for example, can result in carbon monoxide poisoning. When misused, these devices can become real dangers, especially when the room ventilation is insufficient. Health authorities emphasize the importance of precautions to take:

• Never use a portable heater for more than two hours in a row without ventilation.

• Ensure that vents are clear to avoid the buildup of toxic gases.

• Install carbon monoxide detectors in rooms where combustion devices are used.

Risks associated with portable heater use

Using portable heaters, such as those available from retailers like Bricorama, Castorama, Leroy Merlin, or Brico Dépôt, may seem like a practical solution during cold snaps. However, these devices have dangers that it is essential to know to prevent accidents.

Carbon monoxide poisoning

Carbon monoxide is a colorless and odorless gas known to be deadly. Its presence is often due to incomplete combustion of fuel in portable heaters. Poor ventilation conditions or defective devices increase the risk of poisoning. Symptoms, such as headaches or nausea, are often mistaken for those of the flu. Unfortunately, each year, more than 20 deaths in France are linked to faulty usage of these devices. Preventing this danger involves regular maintenance and adequate ventilation of the space.

Fire and explosion risks

Fire incidents related to portable heaters are not uncommon. Approximately 400 cases of domestic fires originate from these devices each year. The causes are often due to:

• Gas leaks.

• Poor storage or placement of combustible objects nearby, such as DIY materials bought from Alinea or Darty.

• Electrical defects.

Burns and various accidents

Burns from direct contact with hot surfaces represent another major risk, especially in homes with children. A significant number of people are hospitalized each year due to complications related to such accidents. Inadequate installations, such as poorly done electrical connections, can also lead to short circuits or, worse, explosions.

Preventing dangers: how to use your portable heater safely

To minimize the risks associated with using portable heaters, it is essential to adopt preventive practices. Here are some practical tips to follow to ensure the safety of your home during winter.

Choosing and installing gas portable heaters

When purchasing portable heaters, prefer models certified as compliant with European standards, available at Thermor or Atlantic. The following criteria should be taken into account:

• Devices equipped with safety features such as flame detectors.

• Installation by a qualified professional and verification of safety instructions.

• Well-ventilated location, away from combustible materials.

Regular maintenance: a crucial step

Maintaining portable heaters is vital to ensure their proper functioning. It is advisable to hire professionals for an annual check-up, which includes:

• Checking the tightness of pipes and connections.

• Quality of combustion and ventilation.

• Detection and repair of any defects.

Daily safe usage

To ensure safe use of portable heaters, here are some practices to adopt:

• Turn off the device before sleeping or in case of prolonged absence.

• Regularly ventilate the room to avoid gas accumulation.

• Never leave a device unattended, even for a short period.

Detection devices: a necessity

Installing carbon monoxide and smoke detectors is a crucial step for the safety of your home. These devices can save lives by quickly alerting occupants to potential danger. Here are some essential points to remember:

Importance of carbon monoxide detectors

CO detectors should be strategically placed in every room where a combustion device is present. Here are some tips:

• Regularly test their operation through periodic checks.

• Change the batteries at least once a year.

• Choose certified detectors to ensure quality and safety.

Compliance with safety standards

It is imperative to adhere to the regulations in force concerning the use of portable heaters. The owner must ensure compliance with standards and make sure that appropriate safety measures are in place. Also check with your insurer regarding coverage in case of accidents related to these devices.

Examples of available devices

To help you make an informed choice, here are some reliable brands offering CO and smoke detectors:

• Groupe SEB - Renowned for its safety technology.

• Thermor - Known for its efficient heating devices.

• Atlantic - Offers a complete range of temperature control systems.
