Patent ·
OSTI ID:5749167

A closed hollow waterproof chamber is disposed below the removable, sectional bottom floor of a building. The chamber is partially filled with water and contains air. The chamber is lined with plastic. A plastic sheet covers the water by resting upon the top surface thereof and is secured to the liner at the periphery in an air-tight manner preventing moisture from entering the building. A solar heat collecting unit is disposed on the roof of the building. The unit has an upper water inlet and a lower water outlet. Both the upper water inlet and the lower water outlet are extended horizontally on the top and the bottom of the solar heat-collecting unit. Water passing through the unit from inlet to outlet is heated by the sun. Water is pumped from the chamber to the inlet and released to flow downwardly to the outlet under the force of gravity and is drained from the outlet to the chamber whereby water in the chamber is heated. A flexible transparent plastic cover is detachably secured to the unit to protect same from external weather conditions. Air under pressure is introduced between the cover and the unit to inflate the cover.
