Do I Need Trickle Vents With a PIV System?

PIV units are an effective method of controlling mould and air quality, whilst introducing filtered and fresh air in the home, and simultaneously extracting the outdoor air. So what is the best way to get the most out of this system?

In this blog, we will be answering the question ‘Do I need trickle vents with a PIV system?’

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.

Explaining PIV systems

Explaining PIV systems

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.

What is a trickle vent?

A trickle vent is a style of ventilation that is usually placed above doors and windows, these vents have a slat that you can open and close. When opened, it allows a small amount of air from outside to enter the home, this helps give an extra level of ventilation as subtle as it may be.

It also must be understood that doors and windows (specifically windows) have their efficiency partly decided by how much heat they can keep in, placing a trickle vent over a door or window can result in the window being less effective, technically.

Do I need trickle vents?

No, trickle vents aren’t a necessity but they do offer a way to cool down a room without having to fully open a window, this is helpful in rainy settings.

Do I need trickle vents with a PIV system?

Do I need trickle vents with a PIV system?

No, you do not need trickle vents with a PIV system, as we mentioned previously, trickle vents are made for doors and windows. PIV systems not only deliver fresh, filtered air, but they also extract indoor air, so a more comprehensive type of vent is required for this function.

Are trickle vents better than a PIV system?

No, a PIV system is the most effective method of ventilating your home with fresh, filtered air. Although trickle vents are effective, they don’t have the expansive reach across your home that a PIV system does.

Will PIV systems remove mould?

If you already have mould in your home prior to installing a PIV system, then no, a PIV system will not remove mould. However, a PIV unit will create an environment where mould will struggle to thrive if at all.

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 cleaner, anti-mould paint and more.

We also sell equipment that helps you monitor humidity in your home (if this is an issue)

If you’re looking for natural remedies for mould, try spraying distilled white vinegar over the mouldy area, leave for an hour then wipe. This method is known to deal with light mould buildup.

Should I install my PIV system myself?

Unless you’re a qualified electrician or have experience in installing PIV systems in the past, then no. You should not install a PIV unit yourself if you have no experience, you don’t want to be responsible for any mistakes that may occur during your installation.

We understand that not all of our readers may have the contacts, or know who to go to when searching for someone to install their PIV unit, click here to find local, trusted electricians.

What if I can’t buy a PIV system?

We are sensitive to the fact that all of our readers may not be able to get a PIV system just yet, so is there an alternative way to get the benefits of a PIV system? You’ll be happy to know there is. It’s as simple as opening your windows.

Opening your windows in your home so there is a passage of air travelling from one side of the house to the other (Upstairs too if your home has multiple levels) will allow any humid, stale air to leave your home, and be replaced with fresh air from outside.

Practicing this method on a daily basis is a basic ventilation routine, that being said, PIV systems do all this without the risk of making the home too cold.

Trickle vents may also be costly to install on each of your windows, depending on your home. Opening windows is definitely the easiest alternative.
