Solar and Ventilation

Ventilation is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings.  Methods for ventilating a building may be divided into controlled (fan forced)  and uncontrolled (open windows).

Energy from the sun heats the air in the roof space or a solar panel which can then be distributed through the home.  This method of heating has the added benefit of introducing fresh air from outside at the same time.  The amount of heat gained depends on the weather and the ability of the roof space or size of the solar panels to harvest the suns energy.  

Every home needs an amount of fresh air ventilation, solar heating provides pre-heated ventilation which is much better than letting cold air into the home via windows and doors.

We provide a range of electric fans that are driven by photo-voltaic panels making them free to operated while the sun is shinning.  These types of fans are suited for applications that may only require ventilation/extraction during the day such as sub-floor ventilation or to exhaust roof heat during summer.

Surplus heat in one room can be transferred to other colder parts of the home.

WarmNdry - Condensation Control System

Positive Pressure Ventilation System designed specifically to improve air quality by introducing fresh air and expelling stale air in an automatic and controlled manner. The roof space provides solar heat gain and allows ducting to distribute air through the home. Crying windows (condensation) is the most obvious symptom that a home has inadequate ventilation. Other symptoms include mould, mildew and musty smells.

Heat Transfer

Heat transfer systems use excess heat to warm other areas of the home by transferring it from one room to multiple rooms. Typical home heating concentrates on warming the lounge, which means you are often ‘Hot’ in one room while the rest of the house is unbearably cold. Heat transfer overcomes this issue by effectively transferring the excess heat from this room to other rooms in the home. For heat transfer to be effective, a source of heat is required as well as suitable air handling equipment and an air return path to allow air circulation to occur. Wood heaters produce excess heat and are ideal for this purpose where as heat pumps normally do not provide the extra heat required to heat the rest of the home. Pellet Fires Tasmania can design a suitable system to meet your individual requirements based on over 10 years experience in this area.

Extraction

The Solar Whiz is a powerful home heat extraction and roof ventilation system without electricity bills or carbon emissions! The Solar Whiz is a powerful solar powered heat extraction fan that operates completely off the grid and is ideal for solar roof ventilation in summer. During winter the fan can be simply switched off so that the roof space retains heat.
