PROBLEM TO BE SOLVED: To make efficient use of a pool by enabling different kinds of underwater exercise for which different temperatures are suited to be simultaneously performed in the one pool. SOLUTION: A multi-purpose pool has tanks 3, 4. Each tank 3, 4 allows swimming or underwater exercise therein. The tanks 3, 4 can be filled with water of different temperatures. The temperature and quantity of water filling each tank are calculated by a control means. The control means feeds the desired quantities of hot water into the tanks 3, 4 by appropriately opening and closing the solenoid switching valves of various pipe lines. |
