<p>An apparatus for heating fluids in which hot water (1) circulates through piping (2) where it initially flows past end (3) of heat pipe (4). Heat pipe (4) communicates with upper warmest section (5) of water tank (6). If the temperature in hot water (1) which circulates past end (3) is higher than section (5) heat energy is transferred via heat pipe (4) to section (5). Hot water (1) subsequently flows past ends (3) of heat pipes (7) and (8) respectively. Heat pipes (7) and (8) communicate with cooler section (9) and cold section (10) of water tank (6). If the temperature of the hot water (1) flowing past ends (3) of heat pipes (7) and (8) is higher than sections (9) and (10) of water tank (6), heat energy is transferred via heat pipes (7) and (8) to sections (9) and (10).</p> |
