Free Heat From Sun
No Grid. No Gas.
No Electric Bill.*
A simple solar thermal system using focused sunlight to heat your home — currently being developed and documented step by step.
Your Heating Bill Goes Up Every Year. There’s a Better Way.
Every winter, homeowners spend hundreds—sometimes thousands—just to stay warm.
Meanwhile, the most powerful heat source available shines overhead every day—for free.
The question isn’t whether it works.
It’s why more people aren’t using it.
Introducing Waller Solar™
Concentrated Solar Thermal Heating for the Home
Waller Solar™ uses a Fresnel lens to concentrate sunlight onto a copper absorber coil.
The heat transfers into a fluid loop, stores in an insulated tank, and integrates with your home heating system.
No solar panels.
No inverters.
No electrician required.
Just sunlight, copper, water—and physics.
