Why is my PIV unit making my house cold? Pros reveal why and how to fix the issue
Briefly

"Positive Input Ventilation (PIV) units are essential for maintaining air quality in homes by diluting stale air, but they can result in colder indoor temperatures."
"Without a PIV unit, homes can face common issues like condensation, dampness, poor air quality, stale air, and even potential health concerns related to mould and humidity."
"Common issues preventing benefits from PIV include poor specification or installation, draughty buildings, single glazing, or insufficient insulation, making homes feel cold."
"While PIV units can effectively address ventilation issues, their performance heavily depends on proper installation and other building characteristics to avoid cold drafts."
