The Short Answer: Yes
If your home suffers from condensation, damp, or black mould, a Drimaster or Flatmaster system is one of the best investments you can make. It's a permanent solution that works automatically, costs pennies to run, and protects both your property and your family's health. But let's break down exactly why it's worth it.
Running Costs: 25p Per Week
One of the most common concerns homeowners have is whether a PIV system will add significantly to their electricity bill. The answer is reassuringly no. A typical Drimaster or Flatmaster unit uses approximately 25 pence worth of electricity per week, comparable to a single low-energy light bulb. The system runs 24 hours a day, 7 days a week, continuously filtering and circulating fresh air throughout your home.
Over an entire year, that's roughly £13 in running costs. When you compare this to the cost of running a dehumidifier in every room, which can cost £1 to £2 per week per unit and still only addresses one room at a time, the savings are clear.
Maintenance: A Filter Every 5 Years
Unlike dehumidifiers that need regular emptying, or extractor fans that need cleaning, PIV systems are essentially maintenance-free. The only upkeep required is replacing the filter, which typically needs doing every five years depending on your environment. There's no annual servicing, no moving parts to wear out, and no daily attention needed.
This makes PIV a genuine "fit and forget" solution. Once installed, it simply works quietly and efficiently in the background.
The Cost of NOT Fixing the Problem
To understand whether PIV is worth it, consider the cost of leaving the problem untreated:
- Redecoration costs: Mould-affected walls need cleaning, treating, re-plastering, and repainting. A single room can cost £200 to £500 to redecorate, and the mould will return unless the moisture problem is solved.
- Damaged furnishings: Mould ruins curtains, carpets, clothes in wardrobes, and furniture. Replacement costs quickly add up.
- Health costs: Black mould produces spores that trigger asthma, allergies, and respiratory infections. The NHS links damp and mould to serious health impacts, particularly for children, older adults, and those with existing conditions.
- Ongoing running costs of alternatives: Dehumidifiers cost £50 to £100 per year to run and only work in one room. Mould sprays need repeated application. Window vacuums need daily use. These costs never end.
- Property value: Visible damp and mould can reduce your home's value and make it harder to sell or rent.
The Benefits You Can't Put a Price On
Beyond the financial calculations, a PIV system delivers benefits that transform daily life:
- Waking up to clear, dry windows with no more morning wiping routine
- Fresher, cleaner-smelling air throughout your entire home
- No more black mould on walls, ceilings, or behind furniture
- Reduced asthma and allergy triggers for your family
- Protection for your decor, furnishings, and property structure
- Peace of mind knowing the problem is solved permanently
How Long Does a PIV System Last?
PIV systems are built to last. With proper installation and a filter change every five years, a quality Drimaster or Flatmaster unit will typically provide 15 to 20 years of reliable service. When you spread the investment over that timeframe, the cost per year is remarkably low, especially compared to the ongoing expense and hassle of temporary fixes.
The Verdict
If you're dealing with condensation, damp, or mould, a PIV system isn't just worth it. It's the most cost-effective, permanent solution available. It costs less to run than a light bulb, needs almost no maintenance, and eliminates the problem at its source rather than treating symptoms. Compared to the ongoing costs of redecoration, health impacts, and temporary fixes that never actually solve anything, PIV pays for itself.
