SolarWhiz 15W Solar Powered Roof Ventilator With Night Kit & Adjustable Thermo/Hygrostat

The 15W SolarWhiz Solar Powered Roof Ventilator is the perfect choice for comfortably ventilating standard-pitched homes of up to 120 square metres. Included is a flexible aluminium flashing that is suitable for metal or tiled roofs. It provides a reliable and energy-efficient ventilation system for your rooftop areas. Crafted with superior-grade materials:

• a sturdy stainless steel fan body
• a lightweight alloy fan cap
• an advanced solar fan
• a competent adjustable solar panel

How it Works

The Solar Whiz runs whenever there is active sunlight reaching the solar panel, it does not include a battery to continue operation beyond daylight. For the majority of installations dealing with heat within roof space, this is suitable as direct sunlight is often the cause of excessive roof space heat. Solar Whiz is an effective solution for hot roof spaces providing an efficient exchange of hot air. For Solar Whiz to provide maximum performance, replacement air must be accessible and professional installation is required. High volumes of hot air can be extracted from the roof space and/or home interior, thus allowing for a much cooler atmosphere in the ceiling and living spaces.

The included Adjustable Digital Thermo/Hygrostat provides total control when your Solar Whiz operates and you can deactivate the system to keep the heat in winter. During periods of exceptional heat, this can enable the unit to operate earlier, preventing heat build-up. Alternatively, you can deactivate the system to retain heat in winter. The Night Kit can still work during more gloomy days or even throughout the night and enables your Solar Whiz to run on mains electricity once the solar charge has depleted.

Powerful Extraction

Harness the power of the sun to keep cool during summer with the Solar Whiz. During the hot summer months, 25-35% of the heat in your home is generated from your roof space. The Solar Whiz uses solar energy to start operating when the sun rises and helps to keep your roof temperature close to the outside ambient air all day.

Moisture and Condensation Control

It is important for any home to have adequate airflow in order to avoid moisture build-ups which can lead to condensation and the subsequent development of mould or mildew. Therefore, it is essential to take measures that ensure proper ventilation within the home to reduce the risk of such issues.
