Boost Speed refers to the increased extraction rate of continuous ventilation units, which are designed to maintain indoor air quality by providing a constant low-level airflow, known as Trickle. When there is a need for enhanced ventilation—such as during activities that generate excess moisture or pollutants, like showering—the unit can switch to Boost Speed to facilitate higher airflow.
Continuous ventilation units are essential in modern UK homes, especially those that are energy-efficient and airtight. These units operate primarily at a low extraction rate to ensure a steady flow of fresh air while minimising energy consumption. However, during specific activities that produce higher levels of humidity or contaminants, such as cooking or bathing, the Boost Speed feature allows the system to temporarily increase its extraction capacity.
Consider a newly built energy-efficient home in London equipped with a continuous ventilation unit. During a shower, the humidity levels can rise significantly. The homeowner activates the Boost Speed function, which increases the extraction rate, effectively removing excess moisture from the bathroom. This not only enhances comfort but also helps prevent mould growth and maintains the integrity of the building fabric.
In the retrofit sector, upgrading older homes with modern continuous ventilation systems featuring Boost Speed can significantly improve indoor air quality. Retrofitting a Victorian terrace house with such a system allows for better management of moisture and pollutants, which is crucial in older properties that may not have been designed with adequate ventilation in mind.
