Questions from Vale of Leven
What is the price of a PIV unit in Vale of Leven?
Guide prices for Vale of Leven use Scotland rates: positive input ventilation (PIV) loft unit, supplied and fitted is typically £775 to £1,350 inc VAT per home. We confirm a fixed price in writing before any work starts.
How much does PIV cost to run?
A standard PIV unit uses very little electricity, comparable to a low-energy light bulb on normal speed. A heated unit costs more in cold spells because the heater switches on when loft air is cold.
Will PIV make my house cold?
Most units temper or reduce the flow when the incoming air is cold, and a heated unit warms it. Placed correctly on the landing, the air spreads gently rather than blowing on anyone.
