How Powered Ventilation Systems Work

What are powered vents and what are the signs that indicate you need one?

Have you ever felt an unexplained discomfort or uneasiness inside your house? Sometimes, even if you have regularly maintained your ceilings, you might still feel that the air inside your house does not seem to move around as it should. This is not healthy, especially if you have infants and elderly, or members of the family with respiratory challenges.

For this reason, many roof experts recommend installing ventilation systems in your house. One type of ventilation systems to consider is the powered ventilation system. Read on to find out more about powered ventilation systems and the role they play in many residences and even commercial establishments.

Powered Ventilation Systems vs Natural Vents

Powered ventilation systems are a type of roof ventilator. Just like standard roof ventilators, these help you get rid of humid and stale air to bring in fresh and new air from the outside during summer. It enables you to balance the cold weather during the winter season to help you manage the winter’s chilly air.

Unlike natural ventilators, powered vents require electric power to run and make the most out of their function. For natural vents, the best example would be your very own windows. Using windows for ventilation, however, is not always practical, especially if there are weather constraints (e.g., cold weather, strong winds). As such, a powered ventilation system is a practical addition and it can be readily available to use for any season.

How Powered Ventilation Systems Work

A powered ventilation system works by using fans, usually attached to the roofs, to pull the hot and dirty air out with greater force. Powered vents are best used in enclosed spaces or in selected areas that may cause extreme moisture and humid air, like toilets or kitchens. Powered vents filter the air that goes in to your home to. They balance the humid and stale air over the clean and cool air or vice versa.

Enclosed spaces without proper ventilation can lead to roof damage or moisture build-up that may lead to mould growths. This can cause much stress to a homeowner, especially since mould may cause harm, and repairing their damage doesn’t come cheap!

Getting Started with Powered Ventilators

As mentioned, aside from relying on natural ventilation, you should also consider installing powered ventilators in your household to avoid unexpected damage to your roof or any part of your home. As choosing the perfect ventilation system for your space can be challenging, you can start by familiarising yourself with the three types of powered ventilators:

  1. Supply: this type of ventilation system brings air in, but it does not remove it. Getting this type of ventilator is not too ideal, especially in bush fire areas, as supply vents may bring in hot and smoky air inside.
  2. Exhaust: these are commonly used in kitchens and bathrooms to that help you remove the humid air from your home. It can be tricky as some exhaust vents do not entirely drive out the air outside but send it into your ceiling or attic that may cause condensation leading to moisture.
  3. Balanced: is a mix of supply and exhaust ventilation. Balanced vents are mostly installed throughout the whole house to balance bringing in the fresh air and removing the condensed air. The typical installation of balanced ventilation goes like this:
  • Vents supply new and fresh air in the bedrooms, living rooms, or entertaining rooms were most people usually gathers and;
  • Vents exhaust the humid and moist air from areas where it is commonly generated in enclosed spaces such as toilets, kitchens, attic, and basements.

Note that these powered ventilators do not filter and remove the moisture from inside a house. However, they help filter the air to remove dust and pollen from the outside.

Should You Install Powered Ventilation Systems In Your House or Building?

You might not be aware that you need a powered vent installed. Here are some signs that indicate it’s time to consider a powered ventilation system installed by your reliable roofing contractor:

  • You’re experiencing uncomfortable hot weather during summertime.
  • There are rust stains on your plumbing system.
  • Strong or foul odours do not disappear as fast as before.
  • There is visible discolouring of floors, wall paints, and tiles.
  • Mould growth appears on the walls and ceiling.

Should you find some of these signs visible in your home, we recommend seeking an expert to further check what type of ventilation would go well inside your house.
