PCT No. PCT/GB97/02066 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Jul. 30, 1997 PCT Pub. No. WO98/04874 PCT Pub. Date Feb. 5, 1998The invention provides a low-profile, solar energy powered, thermosyphon-circulated water heater and storage device (10) comprising: a flat, tilted solar radiation absorber panel (12); an insulated hot fluid storage tank (18); a conduit (20) providing fluid communication between a lower area of said absorber panel (12) and said storage tank (18), and a further conduit (22) providing fluid communication between an upper area of said absorber panel (12) and an upper area of said storage tank (18) to complete a thermosyphonic path between said panel sand said tank. An extended-length heat-exchanger piping circuit (24) having an entry port (26) for cold, line-pressure water, an outlet port (28) for hot water and arranged within said tank (18) to facilitate the transfer of heat between fluid held in said storage tank (18) and line-pressure water passing through said piping (24); and, an electric water immersion heater (30) positioned in a housing (32) located in an upper area of said storage tank (18) adjacent said extended length piping circuit (24). |
