So, here is the sales pitch for the PIV System (Positive Input Ventilation):
PIV systems work as a whole house ventilation system and create a unique and healthy living environment by supplying fresh, filtered air into a property at a continuous rate throughout.
PIV is required when you:
✔ Don’t want to do a full renovation.
✔ Require a whole house ventilation solution.
✔ Don’t want to remove any walls or go back to brickwork.
But here’s the truth of what it is saying - PIV
PIV works as a whole house ventilation system, bypassing the expensive insulation that you would otherwise put in place.
This creates colder, gustier air in the home, which indeed feels fresher. Healthy environments do need fresh air but your home is actually designed for that anyway. The real issue is to take away the condensation but leave the heat in at a continuous regulated rate throughout depending on the humidity level.
PIV is required when you:
✔ Don’t care about heat or heating bills.
✔ Require a door to be left open when it’s operation but don’t want the security risk.
✔ Think that you need to remove all plaster back to the brickwork in the home to solve a condensation problem.
