PURPOSE:To make the titled device small in size and simplify a solar system, by a method wherein high-temperature air heated in a heat collector is directly blown into water contained in a hot water storing tank through a nozzle pipe provided at the lower part of the tank, in a solar system wherein air is used as a heat-transmitting medium. CONSTITUTION:One end of a pipe duct 3 is connected to the heat collector A, while the other end is connected to a blowing nozzle pipe 5 through a check valve 4. Air sucked in through an outside-air intake port 1 is fed to the heat collector A through a pipe duct 2 by a blower B, is heated by solar heat, flows through the duct 3 to the side of the hot water storing tank T, and is introduced into the nozzle pipe 5 through the check valve 4. High-temperature air is blown into water contained in the tank T through nozzles 6, and transfers heat to water while moving upward as minute bubbles, thereby heating water. When air pressure in the tank T reaches or exceeds a predetermined value, an air vent valve 7 is opened to discharge surplus air to the exterior. Hot water thus heated is appropriately dischaged through an ejecting pipe 12. |
