PURPOSE:To save the installation space and improve the appearance of titled device, by containing an external piping in an external piping space formed in a casing below a hot water storage tank. CONSTITUTION:A downwardly elongated piping space 28 is defined between respective R-shaped angular portion 2a of hot water storage tank 2 and respective corner angular portions 27 of heat insulating material 3. On the other hand, substantially L-shaped leg members 29, 29 having side pipe entrance ports 29a... opened at the side face thereof are provided at the right and left sides of lower part of lower heat insulating material 3b in such a state that these leg members 29, 29 are supported by an auxiliary stay 30. An external piping space 31 is formed between leg members 29, 29 and the under surface of heat insulating material 3b. An external water feed pipe 10 connecting with internal pipings such as an internal water feed pipe 9, an internal hot water feed pipe 13, an internal overflow pipe 16, gaseous cooling medium pipe 5, a liquid cooling medium pipe 6 and the like, an external hot water feed pipe 14, an external overflow pipe 17, an external gaseous cooling medium pipe 7, an external liquid cooling medium pipe 8 and the like are guided to and contained in a casing 1. |
