Ventilation in a private house (toilet, bathroom) is a very vulnerable place where there is a large accumulation of microbes, mold, fungal deposits, a high percentage of air humidity favors their reproduction. In turn, this can be dangerous to the life and he alth of a person - the owner of the property.
In the article we will look at how to make ventilation in the bathroom of a private house. We will also offer some recommendations from experts.
Features of the ventilation duct device
Air exchange in any room is a very important component, especially for the ventilation of a bathroom in a private house, as it provides a pleasant microclimate, prevents moisture accumulation, mold formation.
Ventilation designed for living quarters is different and is selected on a number of grounds. There are 2 types:
- natural ventilation;
- artificial.
Natural ventilation in the bathroom of a private house is organized by creating mines during the construction of the house. They need to be cleaned regularly. Artificial is provided by fans and air filters.
Air supply methods
According to the method of air supply, there are the following types of artificial ventilation devices:
- Inlet - supplies clean air to the house directly from the street or from the room into which the opposite side of the duct was brought out.
- Exhaust - pulls out the exhaust air from the room using various ventilation devices.
- Recirculating - mixes part of the air with the outside, heats up to room temperature and feeds back.
How to calculate the required power
To calculate the required power and the required number of ventilation devices you need:
- measure the length, height and width of the bathroom room, calculate the area of the room and the volume of circulating air;
- 5 times the result, but if the humidity in the room is increased, then 7 times.
Basic norms and requirements
Let's consider the basic norms and requirements for the manufacture, installation and operationventilation devices.
According to the documents regulating building codes, the following is required:
- Arrange full ventilation, including changing the ambient air in the bathroom at least 5 times a day, and if there are children, then 7.
- The design of air filtration devices must be protected from moisture, getting wet, splashing, and have at least a small level of moisture resistance.
In the process of installing ventilation coolers and filters, you need:
- Choose a location approximately opposite the front door, very high, preferably at the height of the ceiling minus 10 centimeters for mounting the case and chasing.
- In the bottom of the doorway, carefully make a small hole about two centimeters wide in order for through ventilation to work.
- Limit, create obstacles for liquids and vapors to enter the case.
- Quality and securely attach the cooler to the surface so that it does not fall, diving into water can end especially badly, because the electronic components of the device will simply burn out.
- It is advisable to make a case, which is then attached on top of the fan.
Mounting Methods
The main stages of installation of artificial ventilation of a bathroom in a private house include:
- Preparation of materials, tools, surfaces.
- Mounting the fan case.
- Mounting the fan.
- Design and create the correct electrical cable layout.
- Testing performance with the elimination of identified problems and the final launch of the device.
The first stage is preparation. It is significant and fundamental for creating a ventilation system in a bathroom in a private house. Let's take a closer look at the steps.
Instructions for action
Work sequence:
- Clean the existing ventilation duct and shaft, or drill it.
- Prepare an opening for mounting a fan of the required size into it - the case should freely enter the hole made. To do this, you may need the following tools: a manual professional grinder, a construction chisel, a puncher, a small hammer. Make sure that only the hull grille should be visible from the opening.
Next, install the case and fan cooler:
- Attach the housing and the ventilation unit itself to the prepared hole. Carefully, trying not to damage the main part of the device, the blades and electronics, bring the wires out for the further connection process.
- Fix the cabinet with a bonding agent such as liquid nails, superglue or dowels, but matching the color of the bathroom decor and finishes.
- Use sealant to organize soundproofing.
What you need to install the fan
To install and connect suchan artificial system, like ventilation in a bathroom in a private house, which helps the natural flow of air in the ventilation shaft of a house building, must be purchased:
- self-ventilating device, in terms of power suitable for the volume and size of the bathroom where it will be installed;
- pipe or channel that will act as an air duct in the mine, the radius coinciding with the size of the ventilation device;
- adhesive, bonding agent to choose from: liquid nails, superglue, dowels, silicone sealant, polyurethane foam;
- self-tapping screws, screws, bolts for screwing the protective grille to the body of the ventilating device, depending on the type of installation holes;
- 3-mm square three-phase installation cable;
- switch capable of opening the circuit connecting the power supply of the ventilation device at the same time as the lighting (bulb);
- sealant with antibacterial component for finishing the attachment points to avoid moisture ingress and the formation of fungal and moldy surfaces, the reproduction of microbes and bacteria.
Electrical wiring
After the preparatory and installation processes, the procedure of designing and laying an electrical cable for supplying power to the artificial ventilation scheme assembled according to the project begins, which is dangerous for the premises under repair. What could be dangerous? Usually, such rooms are deaf, unventilated, with very high humidity, therefore, with careless rash actionsin danger of receiving an electric shock.
Step by step instructions
Step-by-step instructions for installing electrical wiring:
- Complete power outage for safety of life and he alth.
- A three-wire wire must be selected to supply power to the fan.
- Make a cable supply from the two-pole switch to the fan. In a two-terminal system, one contact should be a button, which is a light switch, and the other a ventilating device.
- The wire can only be bent at an angle of 90 degrees without breaking.
- Place the cable in holes made by a perforator, corrugation or cable channels to isolate from moisture. But for the beauty of the room and organization, you will have to ditch the wall.
- When choosing the first option after laying the cable, it is necessary to carry out finishing work: primer, cover with putty, after drying, paint or decorate in any other way in accordance with the interior of the bathroom.
- Install a protective grille on the air filter system. To do this, use self-tapping screws, special latches, glue. The most beautiful option would be gluing.
- After all the materials have dried, you can try to turn on the power supply and make a test run of the system.
- Test the system for performance.
- Fix found bugs and problems.
Such a system can be done independently or with the help of specialists. There are many companies that repair and install such systems. But professionals recommend doingventilation in the bathroom in a private house during the construction phase, think about it in advance. If you buy a ready-made house without ventilation in the bathroom, then you need to design the electricity supply well, it is better to turn to electricians for help.
Recommendations from experts
We offer some tips from the masters in order to properly install and select:
- Forced ventilation in a bathroom in a private home is very important if natural ventilation is not strong enough or cannot cover the air volume of a large bathroom.
- Good natural ventilation in the bathroom helps to increase the safety and durability of wall and ceiling finishes.
- An additional source is required to supply constant fresh air. In this case, supply and exhaust ventilation in the bathroom of a private house will be a good solution for the owners.
