(And How to Sell It to Your Customers)
Proper ventilation is vital to all our family’s health and comfort, and with recent growing awareness around air quality, damp-related health risks and evolving regulations, ventilation has become a top priority.
You may be getting more ventilation-related enquiries from customers who are looking to improve their ventilation in their home and for electricians looking to offer real value, a PIV (Positive Input Ventilation) system can be the ideal solution. Not only does it tackle the root causes of moisture build-up, but it also provides a reliable upsell opportunity that genuinely improves the overall indoor environment.
Read on to find out more about PIV systems and how they work, featuring National Ventilation’s Monsoon EnergySaver PIV and how you could sell the benefits of a PIV to your own customers.
What is a PIV System—and How Does It Work?
A PIV system is a whole house air ventilation solution that works by gently introducing fresh, filtered air into the property from the outside. This can either be installed in a loft or on a wall. This creates a continuous supply of air into the home, eliminating condensation in areas that matter most.
The result?
Reduced condensation on windows and walls
A drier, healthier environment
Alleviate mould growth and musty smells in the home
Why Is PIV So Effective to Reduce Condensation for Homeowners?
Condensation often leads to mould, peeling paint, damaged plaster, and health issues like allergies or asthma. A PIV system stops these problems at the source by continuously ventilating the home without the homeowner lifting a finger.
And because it runs quietly and efficiently in the background, it’s a fit-and-forget solution that keeps working long after you’ve completed the job.

Did you know?
More than 4.5 million families in the UK live in social housing and roughly every 30 seconds a complaint for damp is logged. Within the UK, we have amongst the oldest housing stock in Europe. In England alone, 3 million tenants live in homes that don’t meet the governments decent homes standard.
How to Sell the Benefits of PIV to Your Customers
A simple analogy of how PIV works that you can use to explain the benefits of a PIV system without overwhelming your customer with technical jargon:
Imagine a glass of dirty water beneath a dripping tap, over time the constat drip of clean water will dilute the dirty water pushing it out of the glass. Over time the water in the glass will be clear and clean. Essentially, this is how PIV works. Continuously supplies fresh, filtered air to the home pushing out stale, humid air out through natural air leakage and the use of traditional extractor fans.
You can also highlight added benefits like:
Improved indoor air quality
Reduced likelihood of health risks such as allergens and asthma
Long-term cost savings on maintenance and redecoration
Low running costs (often just a few pence per day)
And if you’re upgrading the ventilation system with a PIV system, don’t forget the extractor fans—especially in moisture-prone areas like bathrooms. To maximise the effectiveness of a PIV system, it's recommended to replace outdated fans with a high-performance option like the Monsoon Zone 1 Silence Range. This ensures consistent airflow throughout the property and helps the system work at it's full potential.
