Ventilation Keeping positive
Condensation and mould is an enduring problem that many households face, and can be made worse by energy efficiency improvements that provide better-insulated, warmer homes but don’t allow buildings to ‘breathe’.
To tackle this, unitary fans can be used to improve ventilation and indoor air quality. But another option electrical wholesalers can offer their customers is Positive Input Ventilation (PIV). Tom Wodcke, Product Marketing Manager at Vent-Axia, explains more about PIV and why it’s a great choice for wholesalers to stock.
and air tightness, but unless these homes have adequate ventilation, moisture in the air can’t escape, causing a build-up of water vapour produced by every day activities such as cooking, bathing and showering until condensation occurs. This encourages the growth of black mould and can lead to serious health problems; including respiratory infections, skin irritation and nausea and a negative impact on indoor air quality (IAQ). Condensation can also occur within the fabric of a building and cause costly damage.
C So with condensation and mould
resulting in property damage and affecting occupants’ health, what can be done?
Wholesalers might be familiar with Positive Input Ventilation (PIV) from its use in social housing but it also has wider applications. Suitable for retrofitting in properties with condensation and mould issues, PIV can also be used in private properties to tackle this problem and improve IAQ. In addition, recent research on the problems caused by poor IAQ means that consumers are becoming more aware of these issues and may look to their electrician for ways to

ondensation and the damage it causes to people’s health and homes is a major problem. In an attempt to lower energy bills, many homes have undergone improvements in insulation
tackle condensation and mould. This makes PIV an ideal solution for wholesalers to offer their customers. So, what is PIV and how does it work? Proven to control condensation, PIV systems provide fresh, filtered and tempered air into the home that is drier than the inside. This results in a healthier indoor environment because the percentage of moisture in the home is reduced, and because mould needs moisture to grow, the risk of mould reduces, benefiting both the occupants and the structure of the building. Drawing
warm, fresh air in from the loft, PIV units such as Vent-Axia’s PoziDry Pro filter the
incoming air through high grade
G4 or F7 filters before gently introducing it into the habitable areas of the property using a ceiling mounted diffuser. The diffuser directs the airflow upwards where the incoming dryer air mixes with the warm moist air that gathers at ceiling height. The PoziDry Pro’s discreet diffuser features Smart Air
technology, which increases airflow performance by 10% but at a lower noise level compared to traditional diffuser designs, all while allowing control over airflow direction.
In addition to tackling condensation and mould, there are also a range of additional benefits that wholesalers can use as great selling points when selecting a PIV unit.
Keeping track Popular in social housing, datalogging fans record details of the home environment to allow landlords to clearly track the effects changing lifestyle habits have on a home environment. With intelligent Smart Sense
technology, the PoziDry Pro provides data via a simple interface to show a range of different factors such as energy consumption and length of time spent on each speed. The latter helps to identify properties with high
