One company captures the power of the sun to heat homes.
Energy from the sun travels 93 million miles through space to reach the earth. Radiant energy is transferred when the infrared waves strike a surface. A thermal solar panel can receive this energy and transfer it to fluid contained in the tubes of the panel. Imagine capturing that perfect, endless, free energy and releasing it inside your home.
Since early Roman times, it has been known that the perfect heating system would take advantage of this concept. The Romans built fires in tunnels under their buildings to warm the floors. Today, we use flexible polyethylene tubing, fastened to the subfloor or embedded in concrete, to circulate warm water -- much easier than building fires under your home.
