Are PIV Units Expensive to Run?

PIV units are an effective and proven solution to help regulate ventilation in your home. Ventilation is a key factor in reducing the opportunity for condensation, and eventually mould to arise.

With these vital services offered by these units, it’s only natural to ask, are PIV units expensive to run?’

To prevent mould, fresh air should constantly be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or PIV systems. Almost all of this is facilitated by ducting.

I-Sells is here to provide the answers you need whilst also supplying you with all the information you need to combat mould and have a well-ventilated home.

How a PIV unit works

A PIV unit is a ventilation system that optomises airflow by extracting stale, humid air, and replaces it with air that it has extracted from outside. This outside air is passed through a filter to ensure there are no pollutants entering your home.

Furthermore, PIV units also have temperature settings which ensure that the fresh air entering the home isn’t going to make it colder than it should be.

Here are some benefits of PIV units.

  • Cures condensation dampness – PIV reduces the humidity in the air, curing condensation dampness and preventing mould growth
  • Improved indoor air quality and healthy living environment- Indoor pollutants from cooking and cleaning, as well as outdoor pollutants including pollen and Radon gas, are eradicated from the home
  • A Unique cost-effective solution
  • Meets Regulations – Meets Part F & L of Building Regulations as a low-energy ventilation strategy
  • Easy & simple installation – Typically installed in under one hour
  • System controls located in the ceiling diffuser for easy commission and access for maintenance checks
  • Low maintenance – Filter clean or replacement every five years
  • Energy efficient – System goes into standby during warmer months when there is no evidence of condensation
  • Clinically proven to help allergy and asthma sufferers

Are PIV units necessary?

PIV units are a welcome addition to any home that understands the value of having clean and fresh air in the home. Although there are methods you can use to gain similar results, PIV units are the best method to get those results by far.

What happens if I don’t have a PIV unit?

Not having a PIV unit is not the end of the world, as long as you have extractor fans in the relevant areas of your home, and regularly open your windows, you will for the most part get a similar effect as a PIV system.

Though it must be said, the filter of a PIV system, as well as the heating systems guarantees fresh air for your home, whereas only opening a window and allowing unfiltered air in could be harmful to those with allergies.

Of course, we don’t want to open windows at all when the weather is bad, whereas the PIV units don’t have to worry about at all.

Are PIV units expensive to run?

No, on the contrary, PIV units are extremely cost-effective considering the critical job it does in your home. Depending on the model you select, you can expect yearly running costs of around £5.

In the current cost of living crisis, the cost of clean air in your home for a whole year is cheaper than a meal from a takeaway!

How do I pay the running costs for my PIV system?

As the PIV system uses electricity from your home, the additional running costs of the PIV system will be included with your regular electric bill. You don’t need to pay for your running costs separately for your PIV unit.

Is there a cheaper method than a PIV unit?

Considering the job a PIV system does, you would be hard-pressed to find an alternative method with the same effectiveness and cheaper to run. You could get similar results by opening your windows regularly.

However, doing that on colder days will make your house cold, which you would need to heat up again, which eventually equates to larger energy bills in the end.

Mould can be removed by using mould cleaning solutions, addressing any leaks within the home, and can be kept away through regular ventilation, something which a PIV system takes care of for you.

What can I use to remove mould?

As mentioned previously, we stock a range of mould removal products such as a mould surface cleaners, anti-mould paint and more.
