Is it necessary to close the ventilation of the cellar in winter

Homeowners frequently struggle with the decision of whether to leave their cellar’s ventilation open or closed when winter arrives. This choice may have a big impact on the efficiency and comfort of the house as a whole, as well as the cellar itself. To learn more about the significance of cellar ventilation in the winter, let’s explore this subject.

Maintaining the space’s structural integrity and overall health depends heavily on cellar ventilation. Appropriate ventilation is important during the warmer months to avoid excess moisture buildup, which can result in the growth of mold, musty odors, and even structural damage. But as winter approaches, things shift, and homeowners might wonder if ventilation is still required.

The preservation of warmth in the cellar and energy conservation are two reasons to close the cellar ventilation in the winter. Homeowners try to keep cold air out of their spaces by caulking windows and vents. This can lower heating bills and keep pipes and stored goods from freezing.

On the other hand, keeping some ventilation during the winter months is crucial to avoiding a number of possible problems. Moisture can still build up in the cellar during colder months, particularly if there are any water infiltration sources or if the area is not well insulated. This moisture can cause condensation in the absence of adequate ventilation, which can then encourage the growth of mold and lower air quality.

Moreover, completely cutting off the ventilation in a cellar can result in a stagnant atmosphere that encourages the accumulation of dangerous gases like radon. In homes, radon is a naturally occurring radioactive gas that can seep through the ground. Its concentration can be reduced with adequate ventilation.

In summary, the climate, the state of the cellar, and the homeowner’s priorities all play a role in the decision of whether or not to shut off the cellar ventilation during the winter. Vent sealing can save energy in the short term, but it can also cause long-term problems like mold growth and poor air quality. As a result, homeowners should carefully consider the advantages and disadvantages and think about speaking with a professional to decide which course of action is best for their particular circumstances.

A feature of air exchange in the cellar in winter

The quantity of pipes that make up the ventilation system in cellars varies according to the size of the cellar. There is enough of one pipe with two valves/slides in small areas. You can control both the intake and exhalation of air with their assistance.

Winter cellar ventilation calls for some upkeep; prior to seasonal transitions, it is advised to cover the waterproofing material and insulate the box with mineral wool. This will guarantee that the ventilation system operates normally and continuously.

The temperature in the room may drop significantly on frosty days because cold air circulates more quickly during these times. It is advised to adjust the supply and exhaust pipe valves as a result. The valves overlap when there is a deep frost. The owner makes an independent decision, taking into consideration the characteristics of a specific object, regarding whether to partially or completely close the cellar ventilation in the winter, based on temperature variations.

Even with adequate ventilation and insulation, yoke can occasionally form on exhaust pipes or attempt to condense in the winter. This will, of course, stop normal airflow. It is possible to make cleaning this section of the pipe simpler. Installing a knee at the pipe’s end is an option.

DIY supply and exhaust ventilation installation

Making your own supply and exhaust ventilation is not that hard. Imagine a 6 x 8 m cellar that is 2 m high. In this instance, 180 mm-diameter pipes will be required. This size is perfect for a pre-drilled hole (180 x 180 mm) in the cellar’s ceiling overlap. It is crucial that the ventilation box can be readily coated with the ceiling opening on a vertical axis. Next, we strictly vertically insert it into the ventilation riser that is positioned up against the wall.

Crucial! A windmill-equipped ventilation canal needs to be positioned one meter above the cellar’s roof.

The smooth inner surface of the pipe allows it to be installed in any shape; the most important thing is that it be of good quality and not corrode easily. Utilize asbestos or galvanizing materials frequently.

Checking the ventilation is fairly simple; all you need to do is light a match. There won’t be any air exchange and the concentration of carbon dioxide will rise if it goes out. Larger diameter pipes must be installed in such a scenario. Just apply this straightforward formula to accomplish this: There should be 1 m2 of the cellar’s space and 26 cm2 of air space.

Whether or not to close the cellar ventilation in the winter depends on your particular circumstances. Although closing vents can help keep heat in the house and keep pipes from freezing, doing so runs the risk of retaining moisture, which can breed mildew and mold. Closed vents may be acceptable in a well-insulated, heated cellar, but open vents will help control humidity in a damp cellar. Ultimately, to make the best choice for the comfort and safety of your house throughout the winter, it’s critical to evaluate the insulation, heating system, and moisture levels in your cellar.

Natural ventilation of the cellar in the garage

There are two kinds of ventilation that can be utilized if the cellar is in the basement:

• forced;
• Natural.

The benefit of the latter is that it doesn’t come with a high price tag. When the cellar has a volume greater than 20 m3, she is the preferred option. There is an exhaust pipe and a supply pipe for natural ventilation. Fresh air enters from the street with the aid of the first channel, and the basement air is distributed with the aid of the second. Installing pipes at opposite angles is essential to prevent cold spots and air stagnation in the space.

The cellar hood is raised to its maximum height. There are two methods to mount it:

• through, through the overlap of the garage floor with the output to the roof;
• make a hole in the wall of the cellar.

It follows that in the first embodiment, the exhaust pipe’s length is 50 cm above the roof’s skate portion. Lastly, a visor or deflector should be installed in the ventilation room. He will make an extra vacuum and shield the ventilation from dust and precipitation.

Although the pipes themselves can be made of any material, sewer plastic pipes with a diameter of 10–20 cm are the most common choice. You are able to use asbestos. The diameter of the ventilation ducts is determined by the following formula: 1.5 cm of pipe diameter should be present for every 1 m2 of space.

Crucial! The supply channel is situated 50 centimeters above the cellar floor. To stop rodents and harmful insects from entering, it is best to cover the opening with a small net.

Channels have dampers installed so that the pipes can be easily clogged during frosts. The dampers are round and rectangular, so it’s important to install them correctly. They are independent of the kind of ventilation system, be it residential or utility.

Combined or forced ventilation

This ventilation device allows for year-round air circulation. The weather has no bearing on this kind of ventilation. The output air duct is where the fan is mounted. Try installing in two pipes at once if at all possible. Do not be alarmed; the fan only uses about 100 watts of power when operating. It does not use a lot of electricity.

The answer to the question of whether or not to shut off your cellar’s ventilation in the winter isn’t as simple as yes or no. It mostly relies on a number of variables specific to your area and climate.

First and foremost, it’s critical to comprehend cellar ventilation’s function. Enough airflow is necessary to maintain overall air quality, control humidity levels, and stop the growth of mold and mildew. On the other hand, excessive ventilation in the winter can result in heat loss and higher energy bills.

The climate where you live is one thing to think about. Leaving cellar vents open in areas where the temperature falls below freezing points can let cold air into the room and increase the risk of frozen and burst pipes. Vents can be closed completely or partially to reduce this risk in certain situations.

However, in milder climates, there might not be as much risk involved in leaving cellar vents open in the winter. Heat loss can be avoided with proper sealing and insulation, which also permits sufficient ventilation to avoid moisture accumulation.

In the end, deciding whether to turn off cellar ventilation in the winter should be based on striking a balance between energy conservation and air quality preservation. To evaluate your unique situation and choose the best course of action for your home, it is advisable to speak with an expert.
