What Is Positive Input Ventilation? What Are Its Advantages?

The benefit of a positive input ventilation system may be something to think about when choosing the best ventilation systems for your house. This can help move air around your house, distributing the build-up of pollutants and bringing in fresh air while also preventing issues like mold, condensation, and dampness. 

What is positive input ventilation?

In order to let air enter and exit the house, many conventional “passive” ventilation systems rely on fixtures like vents and air-bricks with gaps. However, there are certain drawbacks to this passive strategy. It is possible for these spaces to be overlooked, blocked, papered over, or bricked over. Even with all the vents clear, there are still gaps in a modern house that can let heat escape or create drafts. This means that air flow is not always ideal. 

Although modern homes are better at retaining heat due to their increased energy efficiency, it’s still critical that they have adequate ventilation. Moisture can accumulate without adequate air flow, resulting in condensation, dampness, and mold growth. According to research, a family consisting of four people produces 112 pints of moisture per week through breathing, cooking, cleaning, and boiling the kettle. 

Natural ventilation can be hindered by energy-saving measures like installing double glazing, cavity walls, and loft insulation. As a result, airflow requires assistance. This assistance is provided by a positive input ventilation (PIV) system, which is mounted in your home’s loft area and takes the shape of a motorized unit. By drawing air in from the outside and filtering it to remove pollutants and impurities, this will circulate positive pressure throughout the house. 

A PIV system can stop the less obvious but still harmful accumulation of moisture and pollutants in your home, much like a pump keeps the environment inside a fish tank from getting slimy and murky.

What are its advantages?

This type of low-pressure ventilation has a number of benefits. No matter what’s going on inside or outside your house, it guarantees a steady flow of clean, fresh air. This may be essential to preventing the accumulation of moisture and related issues, such as the formation of mold and wet areas. A moist atmosphere can worsen certain health issues, like asthma, damage your home in ways that are costly to repair, and generally make it feel uncomfortable.

In addition to dispersing mustiness and odors, the pressurized circulation of clean, filtered air throughout the house can aid in the removal of pollutants that may enter from other areas. By reducing the humidity in the home, a PIV system can help stop the growth of dust mite populations. For kids and adults with allergies or asthma in the home, this may be an additional benefit.

Lofts are frequently relatively warm spaces due to the rising warm air, and the movement of this air by incoming fresh air can have a small but noticeable effect on the house’s temperature. A high-quality PIV unit will have a low-energy motor with cheap operating expenses.
