Central ventilation systems
Low energy costs, lots of fresh air
Ventilation is indispensable but can waste a whole lot of heating energy. This is where a central ventilation system can help. Read on to find out more about the benefits of central ventilation and what you need to know before buying a system.
Consider the following points before choosing a system of this kind.
Central mechanical ventilation systems are not cheap to buy, but you will quickly recoup the purchasing price thanks to the savings you will make on heating costs.
The only significant disadvantage of central ventilation is the complexity of installation. In new buildings, even this is unimportant as air duct routing can be easily managed by sound design and planning.
It is a different story if you want to retrofit a central ventilation system in an older building. In this case, you should consider whether decentralised ventilation may be the better choice for you.
You have chosen your ventilation system. But have you thought about these points?

When choosing a ventilation system, you should also check the technical components, such as silencers and acoustic decoupling.

When installing central ventilation, it is vital to fulfil fire protection regulations.
A mains power switch must also be included so that the ventilation system can be safely disconnected from the power supply for maintenance purposes or in the event of a fault.
If you retrofit a central ventilation system, you can take advantage of lucrative state subsidies.
Funding is also available for installing central ventilation systems in new buildings in many cases. It is worth finding out.
