Electric heaters and humidity
The impact of electric heaters on humidity is due to the way they function. Electric heaters operate by heating coils or ceramic elements that release heat directly into the surrounding air. This process of convection transfers heat by warming the air, but it also removes moisture, leading to dry air.
The dryness of the air can be mitigated by using a humidifier or placing water basins near the heater. Houseplants are another natural way to add moisture to the air while also purifying it. These solutions can improve indoor air quality and reduce the adverse effects of dry air on health and surroundings, such as problems with wooden furniture and musical instruments.
Infrared heaters are an alternative option that minimises the risk of low humidity. Unlike traditional heaters, infrared heaters direct heat towards objects rather than heating the air directly. This results in less direct heat while still warming the room, providing better energy efficiency and maintaining comfortable humidity levels.
Regardless of the heating method, understanding the importance of humidity in the home is crucial. Relative humidity describes the amount of water vapour in the air compared to the maximum it could hold at saturation. Balancing humidity is essential to ensure a comfortable environment and prevent issues associated with overly dry or damp air, such as mould and health concerns.

Infrared heaters as an alternative
Electric heaters are known to contribute to a dry atmosphere, reducing indoor humidity levels. They heat the air and blow it through ductwork and vents, circulating dry heated air within the room. This can lead to an unpleasantly dry environment, causing issues such as skin and eye irritation.
Infrared heaters, on the other hand, provide an alternative that minimises the risk of low humidity. Unlike traditional heaters, infrared heaters operate by directing heat towards objects rather than heating the surrounding air directly. They achieve this by emitting infrared radiation, similar to sunlight, that warms the objects and people in the room. As a result, infrared heaters do not affect oxygen or humidity levels in the room and help maintain consistent relative humidity. This type of heating is also more energy-efficient, as it doesn't require the movement of large quantities of air, resulting in lower electricity bills.
Infrared heaters are available in various sizes and styles, making them a versatile and inexpensive option for warming spaces. They are also safer than other space heaters as their heating coils do not become extremely hot, and they reduce the need for humidifiers. Additionally, some models produce clean heat without a blower, preventing the dispersion of dirt and particulates.
When choosing an infrared heater, it is important to consider the size and features that best suit your needs. Larger units require a dedicated power outlet, while most models have cool-to-touch exteriors, making them safe for homes with children and pets. Smart infrared heaters offer convenient features such as remote controls, timers, and temperature adjustments through a mobile app.
In summary, infrared heaters are an excellent alternative to traditional electric heaters as they provide efficient heating while maintaining comfortable humidity levels. They are cost-effective, environmentally friendly, and offer a safe and healthy option for homeowners looking to combat dry air during the winter months.

Health implications of dry air
Electric heaters can contribute to a dry atmosphere, reducing indoor humidity levels. This reduction in humidity can have several health implications, which are detailed below:
Respiratory Issues
Dry air can irritate the upper part of your respiratory system, including your throat and nose, which are lined with moist membranes that capture dirt, dust, viruses, and bacteria before they reach your lungs. When these membranes lose moisture, their ability to capture particles becomes compromised, increasing your risk of infection. Dry air can also worsen asthma symptoms and lead to bronchitis, sinusitis, and sore throats.
Skin Problems
Dry air can cause skin issues such as dryness, itching, flaking, and tightness. It can also exacerbate existing skin conditions like eczema and acne, leading to painful cracking of the skin.
Eye Irritation
Dry air and dehydration can reduce tear production, causing red, itchy, and irritated eyes.
Nosebleeds
Low humidity can cause the inside of the nose to become dry and irritated, increasing the likelihood of nosebleeds.
Increased Vulnerability to Illness
Dry air can make you more susceptible to illnesses like the common cold. This is because dry air compromises the mucus that usually traps germs and prevents them from entering your body.
Stress and Sleep Disturbances
Research suggests that spending prolonged periods in very dry indoor air may increase stress levels and disturb sleep patterns.
To mitigate the health implications of dry air, it is recommended to maintain indoor humidity levels between 30% and 50%. This can be achieved through the use of humidifiers, indoor plants, or water basins near heat sources.

Solutions to dry air
Electric heaters can dry out the air, causing a variety of issues such as dry skin, chapped lips, and static electricity. Here are some solutions to combat dry air caused by electric heaters:
Use a Humidifier
One of the most effective ways to combat dry air is to use a humidifier. Portable electric humidifiers are easy to use and can quickly add moisture to any space. They are relatively inexpensive and can be placed in rooms where you spend the most time, such as the bedroom or home office. It is important to clean them regularly to prevent mildew buildup. Alternatively, you can opt for a whole-house humidifier installed alongside your furnace, providing steady humidity throughout the home.
Opt for an Infrared Heater
Infrared heaters, including floor, wall, and ceiling heating systems, directly transfer heat to objects and surfaces in the room, such as floors and furniture, without affecting air moisture levels. They provide efficient warmth with minimal impact on humidity, making them a favourable option to reduce dry air.
Combine with a Hot Water Radiator and Indoor Plants
Combining a hot water radiator heater with indoor plants during winter can increase humidity levels while consuming less energy. The plants add moisture to the air, and the radiator provides consistent heat without depleting humidity.
Get a Dryer Vent Deflector
A dryer vent deflector is a simple device that blows warm, moist air from your dryer into your home, helping to increase the moisture in the air. In the summer, you can close the vent to move dryer air back outside.
Address Indoor Air Quality
In addition to using devices to add moisture to the air, it is important to address your indoor air quality. Ensure proper ventilation and consider professional indoor air quality services to improve the overall air circulation and humidity levels in your home.

The impact of temperature on humidity
The relationship between temperature and humidity is a delicate balance that can significantly impact our health and comfort. When the air is dry, it does not retain heat well, and this can be a problem during winter. Electric heaters are known for their energy efficiency, but they contribute to a dry atmosphere, reducing indoor humidity levels. This can lead to uncomfortable symptoms such as dehydrated eyes, a sore nose, and chalky skin.
The "relative humidity" of the air is dependent on temperature. For example, if you heat air at -10°C and 100% relative humidity (RH) to 20°C, the RH will drop to ~10%. This low humidity can cause discomfort and even damage to your health and belongings. Prolonged exposure to dry air can lead to skin and eye dryness, and wood furniture or musical instruments can be affected.
To counteract the drying effects of electric heaters, there are several options. One simple method is to place a bowl of water near the heater to gradually evaporate as the room heats up, adding moisture to the air. Houseplants are another natural way to increase humidity while also purifying the air and improving mental wellbeing.
For a more comprehensive solution, a humidifier can be used to regulate water vapour in the air effectively. Room humidifiers are inexpensive and can improve air quality, making the environment more comfortable. Alternatively, switching to an infrared heating system can provide efficient warmth with little to no impact on humidity levels. Infrared heaters direct heat towards objects rather than heating the surrounding air, maintaining comfortable warmth without depleting moisture.
In summary, temperature and humidity are interconnected, and the choice of heating system can have a significant impact on indoor humidity. While electric heaters are energy-efficient, they can contribute to dry air. To maintain a comfortable and healthy environment, it is essential to be mindful of humidity levels and take appropriate measures to prevent excessive dryness.
