Key points about Ventilation systems
Ventilation technology supports controlled air exchange in homes and buildings. It can remove moisture, improve air quality and, with heat recovery, reduce ventilation-related heat losses. The best solution depends on how the building is used, the airtightness of its envelope and the available routes for airflow.
Technology and planning at a glance
Set airflow according to demand
Living rooms, bedrooms, kitchens and bathrooms have different needs. Good planning takes account of humidity, occupancy, room volume and required air exchange rather than using the same airflow everywhere.
Centralized or decentralized
Central systems need suitable duct routes and room for the unit. Decentralized units can be useful in certain existing buildings. Noise, filter replacement and outdoor air and exhaust air routes must be considered with both approaches.
Heat recovery and upkeep
Heat recovery can reduce energy losses but does not replace correct system design. Filters, fans and air terminals must remain accessible and be maintained according to manufacturer specifications.
How the project is prepared and carried out
- Clarify use and moisture sources
Consider the building, rooms, window ventilation and existing moisture problems.
- Plan the ventilation concept
Coordinate airflow routes, volume flow rates, unit locations and sound protection.
- Prepare installation
Determine the required openings, ductwork and electrical connections.
- Balance and explain
Check air volumes, explain operation and document maintenance points.
Information to include in your enquiry
We need the building type, approximate age, floor plan or affected rooms, and a description of any humidity, odor or ventilation problems.
TOPAL operates in Gelsenkirchen and the surrounding area. Availability at a specific location and the possible appointment date will be agreed when you enquire.
Frequently asked questions about Ventilation systems
Does a ventilation system completely replace opening windows?
A system designed for the actual demand provides the intended air exchange. Windows can of course still be opened; the ventilation concept defines the required background ventilation.
What is the difference between centralized and decentralized ventilation?
A central system distributes air through a duct network from one unit. Decentralized systems serve individual rooms or zones and require different building conditions.
How often must filters be replaced?
That depends on the appliance, airborne pollution and manufacturer instructions. Dirty filters can reduce airflow and hygiene and should be inspected regularly.
