Demand Controlled Ventilation or DCV is a method of ventilation that ensures good indoor air quality.

DCV uses a centralised extract system, warm moist air is taken from all of the wet rooms in a home (kitchen, utility, bathrooms, WC’s etc) these are controlled by moisture and movement sensors. When humidity levels rise within the home, the unit will respond and remove them from the air. Fresh air is supplied via wall vents that are controlled by the moisture sensors (which require no wiring to operate). This ensures a balanced airflow and comfortable air quality within the home.

We here at Enoir Ventilation find DCV’s are a very good way of providing high quality ventilation to older homes, upgraded homes and renovations.

DCV systems are a series of sensors, controllers and ventilation fans working in tandem to control the movement of air in the room in which they are placed. The sensor is continuously monitoring the air quality of the room and providing real time information to the controller. The controller relays this information to the fans and adjusts the rate of ventilation accordingly.

There are several benefits to the DCV system which include:

• Low electrical running costs
• No need for filter changes
• Quiet and continuous operation based on the needs of the home
• No user interface required
• Humidity strips with a 30 year guarantee
