Do Space Heaters Dry Out The Air?

Learn Do Space Heaters Dry Out The Air? By the following post. Space heaters are an excellent option to supplement heat throughout the winter months. When you switch them on, they heat the space and dehydrate the area around them. You may want to use it as a dehumidifier during this period because you know you have some additional humidity.

Will using a space heater help to reduce humidity? While a space heater will evaporate moisture from anything in its vicinity, it will not be able to reduce humidity levels significantly. You should use a dehumidifier for this.

It isn’t true. A room with an electric heater has the same amount of moisture as without one, yet it seems dryer. Warm air can evaporate and hold more moisture than cold air. There isn’t much moisture in the air in a cold room, but it isn’t evaporating from your face, eyes, sinuses, and other body parts.

Although there is still little moisture in a warm room, the warmer air dries you faster. When there is some humidity in the room, putting on a space heater should suffice. However, if you have a lot of moisture, you might consider utilizing a dehumidifier.

How Does A Space Heater Help To Reduce Humidity?

A space heater can and will reduce room humidity. It will move the moist air around for a while before drying it off and causing the moisture to evaporate. But first, remember that warm air contains more moisture than cold air.

Warming the air using space heaters may dry things out, but water precipitates. Because the water molecules are heating up, humidity levels may rise. There is no ventilation linked to the space heater to remove the humidity.


This means that allergies, germs, and mildew can thrive in the walls, wood, and other organic materials. Dehumidifiers are ideal in these circumstances. They use a pump to extract moisture from materials and the air.

It’s better not to use a space heater if the room is excessively humid. If there is a little amount of dampness, though, a space heater can be used to alleviate the problem. But keep in mind that if the environment becomes too dry, your skin will dry up, resulting in a stuffy nose and curly hair.

When Should You Use A Space Heater To Reduce Humidity?

Most newer homes do not have difficulties with excessive humidity in the winter. It is unusual for them to have moisture build-up within the walls. A space heater can help remove moisture from the local area if there is a minor increase in air moisture.

If you live in an ancienter home, it’s possible that you don’t have enough insulation to keep moisture out. Any ice and frost from the night before will melt and damp the inside walls during the day. This spreads throughout the space, raising humidity levels.

When the temperature drops outside at night, the water on the walls refreezes, creating a seal for the room’s humidity. When you turn it on, the space heater then warms up all the moisture and water in the air. When humidity levels are high, it does little to eliminate them.

How To Measure Humidity In A Room?

Get a hygrometer if you’re unsure about the humidity levels in the space. These are used to determine the relative humidity of a given location. You can choose from wall-mounted or portable models. A hygrometer is included in various thermostats on the market.

When Should You Use A Humidifier, Dehumidifier, Or Space Heater?

You should aim for a humidity value of 30% to 50%. If your reading is 60 percent, a space heater can be used to reduce humidity to a tolerable level. However, if your reading is above 70% or 80%, you need to utilize a dehumidifier.

When the humidity level in the air goes below 30%, a space heater will extract even more moisture from the air. Because humidity keeps us warm, this can paradoxically make us feel colder.

In this case, a humidifier should be positioned in the opposite corner of the room from the space heater. Get a desiccant dehumidifier if you want to heat a room while also removing a lot of dampness. These types of dehumidifiers remove heat while boosting the warmth of a room.


Now you understand Do Space Heaters Dry Out The Air? So, while a space heater can significantly reduce humidity, you shouldn’t rely on it when the room is saturated. The heater will only heat up and stir water particles around in this case.

There are some elements to consider when deciding whether or not a space heater will reduce humidity. A space heater will not be beneficial in every case of high air moisture. While a space heater will reduce humidity, it is not recommended for areas that have condensation on the walls.

Frequently Asked Questions

Can space heaters cause dehydration?

While heating the room, oil-filled room heaters do not burn oxygen or lower humidity. They are the greatest options for toddlers and the elderly because they do not dehydrate them. They’re the greatest choice because they don’t cause suffocation, dry eyes, or skin rashes.

Which space heaters do not cause the air to get dry?

There’s no dry heat. Infrared heaters do not produce dry heat, unlike traditional heaters that extract moisture from the air during the heating process. This will help you avoid unpleasant side effects like irritated eyes and throat.

Why does the heating irritate my nose?

A dry atmosphere and hot indoor air will dry up your nasal membranes. And as the mucus in your sinuses dries, it thickens, making it more prone to clog them.

Is it possible to leave a space heater on all night?

It’s not a good idea to sleep with your space heater on all night. Overnight, if the device overheats, turns over, or short-circuits, a fire could start while you’re sleeping. Warm-up your room with the heater before night, then turn it off right before slipping between the blankets.
