Passive solar heating system

Patent ·
OSTI ID:5648494
A solar heated, passive storage heater located in a floor between stories of a multistory building is described. A heat storage medium composed of a one-foot thickness of rock is supported by modular wall panels and a floor made from reinforced modular panels. A thermostat controlled blower forces solar heated air through conventional ductwork and ceramic conduits to the heat storage medium. Air return ducts carry air back to the solar heater. Heat is passively transferred to the building along both the bottom of a floor panel and the top of a slab on the upper surface of the heat storage medium. Reinforcement bars provide enough additional strength to the floor panel to support the heater.
