In short, dehumidifiers don't actually cool down rooms; they remove excess moisture from the air that is increasing the humidity levels, which can make the room feel slightly cooler.
Do dehumidifiers create cool? A dehumidifier will not lower the temperature of your room, but it can make you feel cooler. *Because they don't affect actual room temperature, you shouldn't use a dehumidifier in place of a portable air conditioner—you simply won't get the same effect.
Do dehumidifiers cool rooms? They do more than that! This game-changing solution protects your home and family from the dangers of too-high humidity caused by the summer heat, including irritated allergies, increased mold growth, and much more.
By installing a whole-home dehumidifier, you remove the burden that high humidity can put on your HVAC system, which allows it to control the temperature in your home efficiently and effectively.
Cons of Dehumidifiers
Dehumidifiers collect water meaning they need to be regularly emptied. They also need to be regularly cleaned otherwise black mould can start to grow on the machine , which can induce a wide range of health problems including allergic reactions, lung problems and irritation.
Dehumidifiers are not very effective in extremely low temperatures. This is because dehumidifier coils attract water vapor, and if the temperatures drop too low — below 42 degrees Fahrenheit for example — the vapor would freeze, damaging your machine.
The bigger the dehumidifier (and the higher the wattage), the more watts it'll generally use. Large ones can use up to 500 watts, while the smaller models usually only use about 22 watts. All of these factors can also impact your dehumidifier's energy use.
Yet just looking at the average estimates, we can see a clear winner: a dehumidifier costs on average $0.03 and $0.16 per hour to run, while an AC unit will run you $0.06 and $0.88 on average per hour. So while you could find AC units that cost less than a dehumidifier, most AC units will cost much more.
Firstly, it's worth noting that the most effective place to position a dehumidifier is in the centre of a room. This allows the air to circulate properly around the unit. The only time when this positioning can be disregarded is if the unit has a top-mounted air discharge.
The ideal humidity range for a home should be between 40% and 60%, as anything outside of this range could lead to several problems such as respiratory discomfort, dry skin, and eyes, or even mold growth.
The air in a room cannot be cooled by humidifiers. The room could feel colder due to a cool-mist humidifier. But when it comes to temperature fluctuations, a space seems warmer the if it is humid. And humidifiers add humidity to the rooms.
We suggest a comfort setting between 45%-55% humidity. Even though your air conditioner removes moisture from the air, the areas around your air conditioning system can be a source of water build-up.
Leaving your dehumidifier on all the time can result in dehumidifying too much, leading to a dry indoor environment. It can cause dry air, leading to respiratory issues, dehydrated skin, and static electricity.
It is on warm, humid days like this that mould will grown fastest and a dehumidifier is very useful for stopping that mould growth and for making us feel more comfortable, especially in bed at night.
Here's why: Heat Production Process: As a dehumidifier works, it draws in humid air, cools it to the point where moisture condenses, and then warms the air slightly before circulating it back into the room. This process introduces some warmth, but the effect is minimal.
Keep Your Dehumidifier Away from the Walls
It's easy to assume the best place to put your dehumidifier is against the wall. But it's not! Dehumidifiers suck in and expel air using vents. Blocking any of these vents can reduce your dehumidifier's effectiveness.
Should a Dehumidifier Run Constantly? No, your dehumidifier should not have to run constantly to regulate the air humidity. An optimal humidity level to shoot for is between 30 and 50 percent. Your dehumidifier should reach this in 8 to 12 hours.
How Long Does It Take for a Dehumidifier to Dry Out a Room? The size of the room, the humidity level, and the extent of the water damage are some of the variables that affect how long a dehumidifier takes to dry out a room. A dehumidifier typically needs between 24 and 72 hours to completely dry out a room.
If you're now using a portable dehumidifier in your home, it's increasing your energy bills. If yours is a 50-pint dehumidifier and you run it for 8 hours per day, it could cost you up to $40 per month.
A cost-effective alternative to dehumidifiers
Positive Input Ventilation (PIV) is a comprehensive whole-house ventilation system that eliminates moisture and mould in your home.
Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
'Models that also feature an auto-cut off and auto defrost are great too if you're using it for extended periods,' Marc says. So there you have it – it's absolutely safe to leave a dehumidifier on overnight.
Yes, if an average dehumidifier in an average location were to run continuously it would cost over $700 per year in electricity cost! In general, your dehumidifier will not run 24 hours per day all year long. Even if you assume the dehumidifier ran just 50% of the time, your annual cost would be $363.
In short, dehumidifiers don't actually cool down rooms; they remove excess moisture from the air that is increasing the humidity levels, which can make the room feel slightly cooler.
