Valves and grilles

• What are valves?

  Air valves are grilles, often round, located in the ceiling of the kitchen, toilet or bathroom. Valves ensure that polluted air is removed. In an MVHR installation, supply valves are used in addition to exhaust valves. Supply valves are located in the living room and bedrooms and ensure that enough healthy air is supplied.

• I would like new valves, but which ones are suitable for my system?

  This depends on the room in which you want to install the valves. In the kitchen, bathroom and toilet, you should install exhaust valves. In the living room and bedrooms, on the other hand, you need supply valves. There are different types of diameter: the most common size is 125 or 100 millimetres. To determine the size, you can measure the hole in the ceiling or wall and then be sure of the correct diameter of the valve.

• Do I need valves from the same brand as my ventilation system?

  In general, you can use any brand of valve as long as it has the correct diameter. Intovent offers valves in a variety of materials (such as plastic or stainless steel) and designs. When choosing, consider the diameter and the space where the valves will be placed.

• Are any luxury design valves available?

  There are various design valves available in our webshop.

• Draughts in your home?

  Do you have draughts in your home? You may be tempted to close the vents and grilles, but this is not a good solution. Closing the grilles prevents the ventilation system from working properly and can create an unhealthy indoor climate. It is better to tackle the cause of the draught.

  Possible causes and solutions:

  • The ventilation system is not properly balanced. This can lead to too much air being exhausted, creating a negative pressure in the house and causing draughts through cracks and seams.
    
    • Solution: Contact a professional technician to balance the system. They can ensure that enough air is being extracted and supplied to prevent draughts.
  • The grilles and valves are blocked or dirty. This can result in insufficient air being exhausted, creating overpressure and draughts.
    
    • Solution: Clean the grilles and ensure that sufficient air can pass through them. If the grilles are very dirty, consider replacing them. Note: If the original settings are changed, the ventilation system may become unbalanced.
  • The temperature in the house is unevenly distributed. This can cause air currents that are perceived as draughts.
    
    • Solution: Check that the radiators are working properly and that there is enough air coming out of the grilles. Ensure that there is no furniture in front of the grilles that could obstruct the airflow and move the grilles to a higher position, preferably above the radiators.

  If you have followed these steps and are still experiencing draughts in your home, it may be advisable to consult a professional to diagnose and rectify the problem. Have your ventilation system checked and maintained. A properly functioning ventilation system can help reduce draught problems.

• Can the valves be opened or closed further?

  In most cases it is not necessary to adjust the valves yourself. When a ventilation system is installed by a professional, the valves connected to the system are measured and adjusted accordingly to provide sufficient air flow per room. It is not advisable to change the setting of the valves.
