Basement Dehumidifier in the Winter

Most people have an understanding about the use of a dehumidifier in the basement in the summer. It gets very humid and eventually you go down to the basement and turn on the dehumidifier. The only time you give much thought is when you have to empty that heavy bucket. Do you need a dehumidifier in the winter?

The dehumidifier works on humidity which is really relative humidity. The amount of humidity that the air can hold is relative to the temperature of the air. Warmer air can hold more humidity than cooler air.

Understanding the Problem

To correct basement moisture problems, it is necessary to understand where the water and moisture is coming from. Water and moisture enter from the outside of the building to the basement interior four ways:

  1. Water through the floor.
  2. Water through the walls
  3. Water vapor through the walls and floor
  4. Humidity through the air

Now that Summer is over the air is cooler and thus relative humidity will be lower since cooler air cannot hold as much humidity as warmer air.

However it still rains in the Fall and Winter and the water table can raise up around your house. Concrete is porous. Most homes have a basement that is made of concrete. Water creeping through underground soil crevices creates hydrostatic pressure up from beneath the floors and against the sides of your home.

When this water pressure forms around the foundation the un-sealed concrete starts to absorb the water. This is called capillary action. Water passes through the foundation in the form of water vapor.

The water passes through the porous concrete foundation and the vapor E-vapor-ates into your basement. A simple dehumidifier will not work because it only operates during the warmer months.

A basement ventilation system such as the E-Z Breathe ventilation system will remove water vapor and give air exchanges continuously throughout the year.

When it comes to removing humidity and water vapor you need a ventilation system that works year round. The E-Z Breathe Ventilation System is a better than a dehumidifier because it works 12 months a year and not just in the warmest months. This whole house ventilation system is a device that expels the dampest, most humid & contaminated air from your basement to the outside. It replaces the air in the basement with fresher air from the upper floors four to six times per day automatically with no bucket to empty or filter to replace.

Dryness is paramount to a healthy basement.

If your basement is damp or floods on occasion your first concern must be in controlling the water that invades it. Cracks can be repaired or a French Drain and sump pump can be installed. The French Drain and sump pump will control numbers 1 & 2.

Once the water intrusion is brought under control the next step is to deal with the water vapor and humidity. To remove the water vapor and humidity in the basement a ventilation system is required.
