Sydney home heating solutions

No one likes feeling like their home is a refrigerator during the winter months. And let’s be honest, most Sydney homes aren’t built for being cosy in winter – they’re built for open-plan, bring the outdoors in living. But the good news is that xchange air have a selection of Sydney home healing solutions to keep your home warm, dry and comfortable during winter.

Whole Home Ventilation & Positive Input Ventilation

BREATHE FRESHER AIR. REDUCE DAMP. ELIMINATE CONDENSATION. HELP PREVENT MOULD.

Discover how whole home ventilation & positive input ventilation can help manage excess moisture, improve indoor air quality and create a fresher, more comfortable home.

Whole Home Ventilation & Positive Input Ventilation

Is your home struggling with condensation, musty smells, damp issues and/or recurring mould? If you’re constantly wiping down windows, cleaning mould from walls or relying on mould pots or what we call band aid solutions to manage excess moisture, it may be time to look at improving the ventilation throughout your whole home.

Modern homes can trap moisture, pollutants and stale air indoors, particularly when natural ventilation is limited. Without adequate air exchange, excess moisture can accumulate, creating conditions that encourage condensation and mould growth.

Whole home ventilation and Positive Input Ventilation (PIV) systems help address these problems by introducing filtered fresh air and improving airflow throughout your home.

At Xchange Air, we offer ventilation solutions designed to help manage indoor moisture, reduce condensation and create a fresher, more comfortable living environment. Depending on your home and its requirements, a suitable system can also offer additional benefits such as temperature control and filtered air.

Whether you live in a house, townhouse, unit or apartment, we’ll help you find the right ventilation solution for your property.

What is Positive Input Ventilation (PIV)?
Positive Input Ventilation is a whole home ventilation system that introduces filtered fresh air into your home at a controlled rate. A PIV unit is typically installed in the roof space or the sub floor void, where it draws in air, filters it and distributes it through a ceiling-mounted diffuser or floor vents. This gentle, continuous supply of fresh air helps dilute moisture-laden indoor air and encourages stale air to move out through natural leakage paths and other suitable openings. By improving air exchange, PIV can help manage condensation and force dampness out of your home. We use an F7 filter in these systems. PIV can be installed as a standalone solution or, where appropriate, alongside sub floor ventilation and sub floor insulation. This can be particularly useful when different areas of the home are contributing to moisture problems.

A typical Positive Input Ventilation system works by:

 

Drawing in fresh air: Air is taken into the system from a suitable intake location.
Filtering the air: The system filters incoming air using an F7 filter to help reduce airborne particles like pollutants, mould spores and pollens.


Distributing fresh air: Filtered air is gently introduced into the home, typically at ceiling level.


Encouraging air movement: The incoming air helps dilute stale, moisture-laden indoor air and encourages air to move out of the building.


Some systems also include temperature sensors to engage heaters to temper the incoming air.

 

The result is a more controlled approach to whole-home ventilation that can help manage indoor humidity and improve everyday comfort.

Roof Ventilation Heat Exchange

Solution: Heat Transfer Unit

Do you already have a log burner, flued gas heater, air pellet fire or multi fuel burner? We can help you to make the most of the heat produced and distribute warmth more evenly through the home. By drawing warm air from the room where your primary heat source is into the ventilation system in the roof, we can distribute warm air through the home to other areas such as bedrooms, You get a toasty warm home, not just one hot room, but with only a single heat source to run, saving money on your heating bills.

Positive Input Ventilation

Fix damp with positive input ventilation (PIV)

Either used in conjunction with, or as an alternative to, sub floor ventilation, positive input ventilation (PIV) is a whole home ventilation system. Positive input ventilation means that fresh air is drawn into the roof, filtered, and then diffused into your home at a continuous rate, encouraging the movement of air from inside to out.

A unit is mounted in the roof space and disperses fresh air at ceiling level. The units are fitted with an internal temperature sensor, so that air volume can be increased when the roof temperature is above a set level for passive heat recovery in the cooler months. If temperatures in the roof get too hot, standby mode kicks in to reduce air flow and prevent overheating your home. An option is also available for a unit that discharges into the central hallway – perfect for units, apartments and houses with no roof space.
