How Is the Calculation Made?
The system calculates the property volume, required air exchange, and airflow demand based on the number of people. It then selects the higher airflow requirement, recommended duct diameter, estimated duct length, and number of air distribution outlets.

Ventilation System and Cost
A ventilation system is important for maintaining proper air exchange in residential, office, and commercial spaces. The final cost depends on the property area, ceiling height, number of people, selected system, air ducts, diffusers, heat recovery unit, and installation complexity.
The ventilation cost can vary significantly depending on the type of system and equipment used. Datvale’s Ventilation Calculator allows you to estimate the cost of equipment, materials, installation, and additional components in advance.
Ventilation Installation Cost
The ventilation installation cost includes more than labor alone. To calculate the full budget, you should also consider the ventilation unit, air ducts, fittings, insulation, diffusers, grilles, automation, and other required components.
The more complex the duct route and the larger the property, the more materials and installation work may be required.
Based on these parameters, the calculator automatically estimates the ventilation system cost.
Ventilation Cost
The ventilation cost depends on the selected system, required airflow capacity, equipment brand, duct length, and additional features.
A simple exhaust-only system is generally less expensive than a supply and exhaust system with heat recovery.
If the project includes a heat recovery unit, automation, air heater, or silencer, the total cost will increase accordingly.
Types of Ventilation Systems
When choosing a ventilation system, it is important to consider the purpose of the property and the required airflow.
In the calculator, you can select:
- Exhaust-only ventilation
- Supply and exhaust ventilation
- Supply and exhaust ventilation with heat recovery
- Central ventilation system
The selected type directly affects the ventilation system cost.
Heat Recovery Unit Cost
A heat recovery unit is used to retain part of the heat during air exchange.
The heat recovery unit cost depends on its airflow capacity, technical specifications, filtration system, and brand.
A lower-capacity model may be sufficient for a small residential space, while a larger property may require more powerful equipment.
The calculator estimates the approximate cost of a suitable heat recovery unit based on the required airflow.
How Much Airflow Does a Property Need?
One of the main indicators when selecting a ventilation system is the required airflow, usually measured in m³/h.
The required airflow depends on:
- Property area
- Ceiling height
- Room volume
- Number of people
- Property type
The Ventilation Calculator automatically calculates the required airflow based on these parameters.
For example, a large office or commercial space may require a higher-capacity system than a residential apartment of the same size.
Air Ducts and Ventilation Ductwork
Air ducts are an important part of the ventilation system.
Their cost depends on length, diameter, shape, and material.
The system may include:
- Round air ducts
- Rectangular ducts
- Elbows
- Tees
- Reducers
- Clamps
- Insulation
The longer and more complex the duct route, the higher the ventilation installation cost may be.
Diffusers, Grilles, and Air Valves
Air is supplied to and extracted from rooms through special air distribution components.
These may include:
- Diffusers
- Ventilation grilles
- Air valves
The required quantity depends on airflow, number of rooms, and the system design.
The calculator automatically estimates the approximate number of required components.
Additional Components
A complete ventilation system may also include additional components.
For example:
- Silencer
- Backdraft damper
- Fire damper
- External grille
- Air heater
- Filters
- Automation
These components affect the comfort, safety, and control of the system and are reflected in the final budget.
Ventilation Installation
Professional ventilation installation includes more than simply installing the ducts. The entire system must be assembled and configured correctly.
Installation work may include:
- Air duct installation
- Ventilation unit installation
- Insulation installation
- Electrical connection
- Installation of diffusers and grilles
- System commissioning
- Airflow balancing
Proper installation is important for efficient and stable system operation.
What Affects the Final Ventilation Cost?
The final cost is mainly affected by:
- Property area
- Ceiling height
- Number of people
- Required airflow
- Ventilation system type
- Heat recovery unit cost
- Air duct length
- Duct diameter
- Number of diffusers and grilles
- Automation
- Insulation
- Installation complexity
Changes in these factors can significantly affect the ventilation cost.
How to Use the Ventilation Calculator
First, enter the property area, ceiling height, and number of people.
Then select the property type and the preferred ventilation system.
If necessary, you can also select an air heater or other additional features.
The calculator automatically estimates:
- Required airflow
- Recommended system
- Estimated duct length
- Number of diffusers and grilles
- Equipment cost
- Material cost
- Installation cost
- Additional expenses
The result will help you estimate the ventilation system cost in advance and plan the ventilation installation cost more accurately.
