Ventilation survey reveals impact of poor indoor air quality


Ventilation specialist EnviroVent has revealed the startling results of its national survey to mark Clean Air Day (19th June), which demonstrated that 66% of people had experienced mould in their homes.


builds as well as retrofi t installations. Your customers will also want the highest ERP rating of A+++ and the best possible co-effi cient of performance (COP), a key metric for thermodynamic effi ciency. Other features that make life easier for residents and installers are a user-


friendly LCD interface, automatic weather compensation, and remote monitoring capabilities.


6. Product support


While there are many benefi ts to becoming a heat pump installer, it does come with some additional challenges. For example, there can be longer lead times than for putting in a gas boiler – this is because most homes will require an upgrade to their electricity grid connection in order to power the pump. The installation process can also be more complex and take longer than a boiler change.


It is therefore vital that you choose your heat pump provider carefully. Find one with a fantastic reputation for product training, advice and ongoing support. A good indicator is their track record in the boiler business, as well as a proven history in heat pumps.

t a time when awareness of the importance of indoor air quality is heightened and Government legislation to protect people from the impact of poor indoor air quality, Awaab’s Law, is due to be implemented in October 2025, EnviroVent has called these fi ndings ‘extremely worrying’.


A The study of 200 householders revealed that 29% of people were asthma/


allergy suff erers, with 16 per cent of people stating that they felt poor indoor air quality negatively impacted their health. This includes allergies, asthma, chest infections and coughs, whilst eleven per cent of those surveyed said they had trouble breathing at home. The survey also found that 59% of those surveyed had taken steps to


improve their home’s indoor air quality and 92% of people believed indoor air quality to be very important or fairly important. Ruth MacEachern, product manager at EnviroVent, explained: “The results of the survey are extremely concerning, as a high proportion of households are still suff ering the eff ects of poor indoor air quality. Condensation and mould are symptoms of a home that has high humidity levels and lacks proper ventilation. However, mould is more than just an eyesore, it’s a potentially dangerous fungus that releases airborne spores that are an irritant and can exacerbate asthma and other respiratory conditions.” Ruth added: “Good ventilation in the home is essential for maintaining


a healthy and comfortable living environment, lowering humidity levels, off ering longer term benefi ts over and above other options like dehumidifi ers. Mechanical ventilation systems are becoming more popular in the home as they help to reduce condensation and mould growth and work autonomously in the background.” EnviroVent provides a range of ventilation products, which introduce fresh


fi ltered air into the home and remove stale, moist area or a combination of both.
