Roof mounted solar air heater panels.
Solar air heat collector panels are mounted in North facing arrays, inclined at 50 degrees for optimum year ’round solar capture.
Fresh air is heated by the sun
Fresh air flows through 2,000 small holes in the back of the panels then through air permeable material where the solar radiation heats the air.
Heated air flows into your home
Heated air flows from the heater panels through heavily insulated ducts then into your home through stylish ‘ceramic look’ registers.

How effective is it?
The system creates a spectacular EROEI (energy return on energy invested) using only 16 watts to harvest a flow of 2800 watts of heat energy from your roof mounted heat collector panels.
This fresh heated air will displace moisture and VOC (volatile organic compound) laden air in your home with fresh air heated to around 40 degrees above the outside ambient temperature in full sun. The system will continue to run even in overcast weather as long as the panel temperature is above the room temperature.
Operating the system will lower the relative humidity of the air in your home from around 75% to around 50%. Your furnishings, bedding, carpets and clothing will be dry and fresh and the the air will be healthier for you to breathe. Research has shown that air between 45% and 55% relative humidity is ideal for respiratory health.
The system produces 400 cubic metres of warm, filtered air for every hour of operation. This flow will affect the air mass right throughout your home. The slight positive pressure in the building means the air will find its way out flowing through exhaust fans and any gaps around window and doors.
When you need operate your back up heater, the drier air mass will be heated using much less energy. This is because when we add heat to a room, we don’t heat the air, we heat the moisture in the air. This should significantly reduce your reliance on wood or electricity for heating even eliminating their use during most of spring and autumn. The fresh dry air mass means your carpets, clothing and bedding, will be always be dry and warm.
Why solar heating?
Invented by Danish engineers in the seventies, solar air heater panels look much like ordinary solar panels. But when it comes to heating your home, these panels produce direct solar heated air at an energy output rate four times(per per square metre) greater than P.V. panels. The panels produce significant heat even in overcast conditions.
Researchers tell us that its not so much outdoor air that affects our health, its the air inside our homes that has a corrosive effect on our health over time. This applies to most homes but, ironically, newer homes that are well sealed tend to have high levels of CO2 and toxic volatile organic compounds(VOCs) because of very low passive air change rates.
Unlike other heating systems Python Solar produces heat in the form of fresh air. As well as heat, typical installations provide 2-3 air changes for the entire house during cold weather. If indoor air quality is important to you, Python Solar Air Heating is a logical choice.
Unlike grid connected solar P.V. systems, where feed-in tariffs are reducing or disappearing altogether, Solar Air Heating systems offer customers a significant degree of energy independence. Solar heated air is virtually free… forever.
Our heritage gas fields in Bass strait are now declining at 18% annually. Gas will be needed for industrial processes and for open cycle gas turbines to provide smoothing for the electricity grid as renewable electricity scales up. Gas prices are now inextricably linked to world markets and will only rise with growing demand in the future.
What about cooling? The Python system takes advantage of the phenomenon of nocturnal radiation to cool your home on summer evenings. Glass and aluminium readily give off their heat to the night sky. The panels will fall to a temperature up to three degrees below the ambient temperature. On a 16 degree summer night, a flow of 13 degree air will cool your home to a low base for the next day, minimizing or eliminating the need for airconditioning.
We believe the solar heating industry is in its nascent form, similar to the solar photovoltaic industry ten years ago. We have a vision of solar heating systems installed in almost every home in the next ten years.
We are solar heating professionals. We use only the finest quality materials and we always insulate between dissimilar metals on our roof mountings to prevent electrolysis.
We’ve been installing Solar heating systems in Geelong, Melbourne metro and regional Victoria since 2009.
The intelligent touchscreen controller has some truly extraordinary features. It will display outside, inside, heater panel/roof and set temperature on the one graphical interface so you can see at a glance how your system is performing. It also produces a graph to show how it has performed over a 24hr period and stores data from the last 10 days. It controls dampers for warm/cool air source and extra zones in your home.
Brush-less DC fan with motorized damper
Using just 16watts, our unique axial flow, brush-less DC fans will flow around 400 cubic metres of fresh, solar heated air into your home. Each fan flows sufficient air to serve up to four heat collector panels.
The motorized damper closes snugly as the fans go off duty. This way, accumulated heat is captured inside your home and not lost through the ducting.
