Top Questions & Answers
Here are the top questions we’re frequently asked about our PIV installation service…
A PIV fan works by drawing clean air from outside your property, typically through your loft space, and gently filtering it into your home. This creates a slight positive pressure that pushes out the stale, moisture-laden air through natural ventilation points like windows and doors. The system operates continuously at a low level, making it both energy-efficient and effective at reducing condensation, damp, and mould issues.
Most PIV fan installations can be completed within a day. The exact time depends on your property’s layout and any specific requirements. Our electricians work efficiently while ensuring every aspect of the installation is done properly. We’ll give you a clear timeframe during our initial assessment.
Modern PIV fans are designed to operate very quietly. Once installed in your loft space, most people barely notice them running. The systems we install use advanced technology that ensures minimal noise while maintaining effective air circulation throughout your home.
PIV fans are remarkably economical to run, typically costing between £1 to £2 per month in electricity. The exact cost depends on your specific system and usage, but PIV fans generally use about as much energy as a low-wattage light bulb. This modest running cost is often offset by reduced heating bills, as better-ventilated homes tend to heat more efficiently.
Yes, PIV fans are particularly effective at reducing condensation and preventing mould growth. By continuously introducing filtered, fresh air and maintaining positive pressure in your home, they significantly reduce humidity levels. Most of our customers notice a marked improvement in condensation issues within the first few weeks of installation, with many reporting the complete resolution of previous mould problems.
