'The Silent Killer'

Carbon monoxide is one of the most dangerous gases for humans. It is an odorless, invisible gas that prevents oxygen transport. Therefore, it is also called the "silent killer". This gas is produced by incomplete combustion processes, which can occur, for example, in house fires, defective heating systems or even cigarette smoke.

With the help of the smart Weber Protect carbon monoxide detector, you keep the CO concentration exactly in view. The German voice assistant and the LCD display always inform you about the current CO values, and alerts you immediately to increased carbon monoxide values.

WP 616


The WP 616 is a smart carbon monoxide detector that meets the highest European safety standards. Therefore, it is tested and certified according to the EN50291 standard. Many innovative features distinguish the WP 616 from conventional carbon monoxide detectors. The intelligent voice assistant makes installation and operation of the detector particularly easy and convenient. During installation, simply follow the voice prompts and the detector is ready for operation. Even after that, the voice announcement helps the owner by immediately announcing a warning in case of increased CO content or low battery. An LCD display always shows the current CO level. This is displayed in the form of (ppm) between 0 and 999. The LCD display also provides information about low battery. This way you can always be sure that your device is working optimally at all times. A modern electrochemical sensor ensures that the CO content is accurately measured and displayed at all times. Error messages and false alarms are thus almost eliminated. In addition, the WP 616 works for a very long time without battery replacement. In addition, the supplied installation kit allows for quick installation.

Carbon Monoxide Guide

What is Carbon Monoxide?

Carbon monoxide is a chemical compound between carbon and oxygen. Carbon monoxide is an extremely toxic, invisible, odorless and colorless gas that is undetectable to humans. The poisonous carbon monoxide gas (technically called carbon monoxide) is a chemical compound of carbon and oxygen and is also called CO in the molecular formula. This gas, unlike carbon dioxide, is not naturally occurring in the atmosphere and is formed only under the action of external sources. The peculiarity of carbon monoxide is that the gas is odorless, tasteless and colorless. The gas is therefore difficult to detect. It is formed during incomplete combustion processes of fossil fuels such as gas, oil, wood, charcoal or gasoline. Carbon monoxide prevents the transport of oxygen through the blood and can therefore be fatal to humans.

How is carbon monoxide formed?

Carbon monoxide is a by-product that is produced by incomplete combustion processes with insufficient oxygen supply.

Therefore, the toxic gas is usually produced in appliances such as stoves, furnaces, heating systems, grills, broilers, chimneys and ventilation systems.

In normal operation, the above appliances have a sufficient oxygen supply so that the fuels can burn completely and the small amounts of CO that are produced are harmless.

However, should these devices become defective or dirty, it can quickly become fatal. If an adequate oxygen supply is not provided, the fuels will not be completely burned during the combustion process and the CO content of the air can quickly increase.

What Makes Carbon Monoxide Dangerous?

Carbon monoxide is a light gas which, unlike smoke, spreads evenly throughout the room. Thus, it does not move upward, toward the ceiling, but remains distributed throughout the room.

A high carbon monoxide concentration in the air ensures that not enough oxygen is inhaled. As a result, dangerous symptoms caused by carbon monoxide poisoning become noticeable. Learn more about the symptoms of carbon monoxide poisoning in the next section.

What are the symptoms of carbon monoxide poisoning?

The occurring symptoms in carbon monoxide poisoning can be very versatile and more or less dangerous. In mild poisoning, symptoms such as dizziness, headache and nausea have been observed. Long-lasting carbon monoxide poisoning has much more severe symptoms. This can include very severe headaches and even confusion. Also, when hemoglobin and carbon monoxide combine, the skin turns pink or rosy.

In cases of prolonged carbon monoxide poisoning or very high carbon monoxide concentrations, unconsciousness and death may occur after a short time.

If one or more of the above symptoms can be detected, it is important to take the measures listed in the next section to protect yourself.

How do you protect yourself from carbon monoxide?

Carbon monoxide is produced, among other things, during combustion processes without sufficient oxygen supply. The most common causes or reasons for carbon monoxide poisoning are primarily defective or insufficiently maintained heating systems, gas boilers or exhaust air ducts.

It is therefore particularly important that these and other devices in which combustion processes take place are regularly checked by specialists.


Appliances to be inspected include:

  • Gas boilers, instantaneous water heaters and any gas-fired appliances

  • heating systems burning fossil fuels (oil, wood, gas)

  • Chimneys and other exhaust and supply air ways


Although prevention is the most important step in protecting against carbon monoxide poisoning, possible malfunctions in appliances can never be completely ruled out. In addition, CO gas generated in adjacent homes can also become a potential hazard.

An effective protective measure is to install a carbon monoxide (CO) warning alarm.

If you notice symptoms of carbon monoxide poisoning in yourself or others, immediately ventilate the room and contact 911.

Carbon Monoxide Facts and Figures?

There is not much cozier than sitting in front of the fireplace on a cold day. But quite unknowingly, the fireplace can quickly become a hazard. Defective heating systems can also quickly become the cause of a carbon monoxide leak. Hidden dangers lurk in every home!


Here are a few facts about carbon monoxide:


  • The gas fireplaces in over 130,000 German households have excessively high exhaust levels.

  • Carbon monoxide is completely odorless, invisible, non-irritating and cannot be tasted.

  • Across Europe, more than 1000 people die of carbon monoxide poisoning every year

  • Carbon monoxide poisoning is often mistaken for a common flu or cold and therefore not treated properly.

  • In Germany, the Kehr- und Überprüfungsordnung (KÜO) regulates which appliances must be inspected and at what intervals.

  • Since the beginning of the nationwide reporting obligation, more than 60,000 medical notifications of carbon monoxide poisoning have been reported to the BfR.

  • Children, the elderly and pregnant women are particularly at risk of carbon monoxide poisoning.

  • Pets are just as affected by carbon monoxide as humans.

  • Carbon monoxide detectors greatly minimize the risk of carbon monoxide poisoning.

How does a carbon monoxide alarm work?

By installing a CO detector, the dangers of carbon monoxide poisoning can be minimized.

CO detectors permanently monitor the concentration of carbon monoxide in the ambient air and issue a loud alarm in good time, even before threatening levels are reached.


Most carbon monoxide detectors measure air levels using an electrochemical sensor. These measure extremely accurately and reliably.


However, please note that these carbon monoxide alarms are not a substitute for regular maintenance and compliance with safety regulations, but only a further step towards protection against carbon monoxide poisoning.

Where do I install carbon monoxide alarms?

To know where to install carbon monoxide detectors, it is important to understand how carbon monoxide gas behaves. Smoke always rises to the ceiling and usually collects in the center of the room. For this reason, smoke detectors are also installed in the center of the ceiling.


With carbon monoxide, things are different. The carbon monoxide gas distributes itself evenly in the room. Therefore, it does not make sense to install the CO detector on the ceiling, because it would take too long for the carbon monoxide gas to reach the CO detector.


For this reason, the CO detector should be installed close to the point of danger (min. 1 meter / max. 3 meters). In bedrooms and recreation rooms without acute danger points, the CO detectors should be installed on the wall at breathing height. When mounting, it should be noted that the CO detector must be installed freely and at a distance from blocking objects to provide optimum protection. CO detectors can also be used free-standing. Here, too, the same rules as for wall mounting must be observed. 


CO detectors should be installed in any room where there is a fuel-burning appliance. In addition, it makes sense to install CO detectors in bedrooms, as we cannot notice the carbon monoxide gas at night and therefore quickly become unconscious and, in the worst case, do not wake up.
