Home ventilation systems from HRV Australia

Is your roof space hot this summer and heating up your home? HRV Australia has developed an ingeniously simple device to work in conjunction with its award winning natural heating and cooling system. The 'Purge-Air-Lator' has undergone testing during this summer and the latest evolution means that you can automatically purge hot air from your roof space when it reaches a pre-set temperature.

This means that the roof cavity gets ventilated by blowing out the hot air and drawing cooler air, significantly reducing peak temperatures in the roof space during the day and cooling it faster at dusk. The result is a significant reduction in the super heating of ceiling insulation and then radiating down into the home during the day and evening.

The major advantage of controlled ventilation of the roof cavity is that during winter, the warm blanket of air is not evacuated, unlike uncontrolled ventilation which significantly increases household heating requirements.

HRV has a fundamental aim to reduce the unnecessary use of artificial heating and cooling by intelligently using warm or cool air which is freely available. To see how HRV uses naturally occurring warm or cool air to keep your household at a comfortable temperature visit www.hrv.com.au
