Easy to Build Solar Furnace

 

Solar furnace workshop 2 002 (Small).jpg

Description;  This is a solar collector that is heated from the radiation of the sun and is transferred by conduction of the elements in the collector. The heat is captured by aluminum tubes that are painted black. The heat rises to an exhaust area where it is directed to be used. Fans are sometimes used to increase the harvesting of the heat. Heat loss is reduced by insulating the panel and covering the radiation area with glass.

 

Expectations;   Here on Vancouver Island we can expect to have the air heated to well over 100 degrees Celsius on clear summer days. The greatest use for home heating is during cooler days. Cloudy days will greatly reduce the heat level. High heat can be achieved on winter days when the sky is clear.

The panel can help reduce the energy that we use in our homes. The heat capture can be saved if blown into a heat sink of some kind and used at a later date.  

Parts of the panel

Box, to frame and seal tubes and support glass.

Tubes, to capture radiant heat from the sun and give heat to air moving through the tube.

Tube mount, to seal tube interior away from heated area to allow clean air into living space.

Insulation, to stop captured heat from escaping.

Header and Foot cavity, to allow air to be captured and supplied.

Glass, allow radiation to reach tubes but keep air from cooling tubes.

Fan, to increase movement of hot air to destination and to keep panel from overheating.
