Moreover, the hot water in the boiler shell 1 is directly used for heating water that does not require fresh water. That is, hot water sent to the hot air fan 26 by the circulation pump 27 and used for heating by the hot air fan 26 is returned to the inside of the shell 1 through the distribution pipe 30.

が可能となる。Incidentally, the danger due to the volumetric expansion of the hot water in the boiler shell 1 is reliably prevented by the expansion pipe 24, and the expanded hot water is led to the distiller 22 by the expansion pipe 24 and is returned to the shell 1 as make-up water. By circulating the hot water for heating and the expanded hot water back into the boiler shell 1 in this way, heat exchange between the water and the flue 4 is further promoted and efficiency is improved. Moreover, if the boiler is installed on the roof of a building or the like, it is advantageous in terms of the head, and the water supply pump can be omitted or downsized.
本発明は以上詳述した構成にて初期目的を有効達成した
。先ず、ボイラ胴１がコンクリートにてた、胴１内の水
は一旦温まると冷めにくく、熱交換の効率が向上する。The present invention has effectively achieved its initial objective with the configuration detailed above. First, the boiler shell 1 is made of concrete, and once the water inside the shell 1 is heated, it is difficult to cool down, improving the efficiency of heat exchange.
次に、横方向の上下に平行する略Ｕ字状に煙道４を配設
したから、胴１内の水は上部と下部で有効に加温され、

も一台で稼動できるという利点もある。Next, since the flue 4 is arranged in a substantially U-shape parallel to the top and bottom in the horizontal direction, the water inside the shell 1 is effectively heated at the upper and lower parts.
In addition, burners 7 are installed at three locations at the base end 6 and the folded portion 8 of the flue 4.
．． 9, it is possible to use two burners 7.9 in the cold winter. Another advantage is that even if one unit breaks down, it can still be operated with just one unit.
