Abstract (en)
[origin: EP0309199A2] A hot water boiling apparatus includes a hot water tank (11) filled with water. A water supply pipe (14) and a hot water supply pipe (17) are connected to the bottom and top of the tank, respectively. A bubble pump unit (20) is arranged in parallel with the tank. The pump unit includes a body (27) having a boiling chamber (67), electric heaters (24a, 24b) for heating the water in the chamber, a first connecting pipe (30) for guiding water from the tank to the body, a guide pipe (36) for feeding the water, guided through the first connecting pipe, into the boiling chamber, and a second connecting pipe (33) for guiding the water heated in the boiling chamber into the upper portion in the tank. The guiding pipe is arranged so that heat is exchanged between the water in the boiling chamber and the water flowing through the guide pipe.
