Heating your home with free energy from the sun is easier than you think. There are many different solutions to creating a DIY solar heat collector to heat your home naturally, efficiently and best of all, cheaply (free!).
By understanding the dynamics of thermosiphoning, you can create panels that provide free heat to your home using the power of the sun to heat air. The basic unit will sit into your window or wall opening and direct heat into your home using the natural ability of heat to rise.
Actually its cold air that sinks, causing hot air to float on top of it. And it’s using this principle that you can solar heat air in a panel of heat absorbent material and cause it to rise into your home, removing cold air as the thermosiphoning works its magic.
The solar absorbing material is the most crucial piece of this equipment. A basic aluminum or sheet metal panel painted black with a 6″ air pocket inside of it can heat air quickly and efficiently. A glass window is attached to the top of the vent. This in turn is stacked or set next to an additional insulated chamber that removes cold air from the home. An old heating duct and a window can make the perfect free solar heat collector.
This unit is then attached to the most sunlight side of the home, either through and existing window or an opening cut into the home. As hot air is heated through the chamber, it rises and is replaced by cooler air as it is pumped in through the window opening using natural convection. This easy to create unit works it’s magic without any electricity or added HVAC equipment.
A much larger version of the solar hot air collector can be built using these blueprints. This model is a shed like addition to an existing window opening on the southern facing area of your home. It’s a simple 5×8 structure that can easily be built in a weekend and save you tons of money each year on your heating bill.
