Roof ventilation is crucial in maintaining a healthy and comfortable home environment, especially in winter. The iSwirl roof top ventilator plays a beneficial role in winter by helping to expel excess moisture from your roof cavity. This reduction in humidity can create a more comfortable internal home environment by alleviating that chilly sensation often caused by damp air.
In winter, we turn on the heat to keep our house warm. When this warm air rises into the roof cavity and meets the cold air, it creates moisture. The constant air flow helps prevent dampness caused by the warm air getting trapped in your roof. This not only contributes to improved air quality, but also a healthy living environment for you and your family. People worry that whirlybirds would drain their heating system or cause their house to get colder, but that isn't true! Instead of drawing air from your internal rooms, the iSwirl does so from your roof cavity. So the moist, stale air is forced out, and the heat remains inside!
The self-sufficient solar-wind powered iSwirl Ventilator is designed to improve roof airflow and offers a year-round solution. It utilises the energy of sun and wind to draw hot air out from the roof and replacing it with clean air. This process helps prevent heat buildup in summer and minimise heat loss in the winter.
Standard Whirlybirds (also known as turbine vents) rely solely on wind, which might not be able to adequately ventilate your roof space if there is little or no wind. This lack of airflow can lead to a buildup of moist air, which is undesirable in the winter.
Factors Influencing Heat Loss in Winter
Several factors play a crucial role in determining whether your home will be negatively impacted during winter. These include:
- Home Insulation: Poor insulation is a significant contributor to heat loss. If your house has inadequate insulation in walls, roof, or windows, heat will escape, making your house feel cold and will likely increase heat loss.
- Air Leaks and Drafts: Air leaks and drafts are another major source of heat loss, allowing cold air to enter and warm air to escape.
- Heating System Efficiency: The efficiency of the home's heating system is a critical factor. If the heating system isn't powerful enough to compensate for the increased heat loss, the home may feel colder.
The Verdict: No, Roof Ventilators Won’t Make Your House Colder in Winter
