P.I.V units are energy-efficient, but running costs vary throughout the year. Based on real-world usage, a fair estimate for the annual average running cost is 25-30p per day.
A breakdown of estimated costs:
- Warmer months: Fan only (~10p per day)
- Milder months (March, October, November): 20-30p per day (occasional heater use).
- Coldest months (December - February): 40p - £1.00+ per day (frequent heater use).
Overall, they remain a cost-effective solution for improving air circulation and reducing moisture-related issues, but users should expect higher electricity usage during colder months.
