CONSTITUTION: A boiler(100) includes a heating chamber(10) and a heat exchanging chamber(20) which are closed by an insulation member(104) and divided from each other by a partition(101). Bricks(30) are stacked in the heating chamber(10). Grooves are formed in the bricks(30) so as to accumulate heat. A plurality of heaters(40) are provided by transversely passing through the grooves of the bricks(30). The heaters(40) are operated by electricity of midnight. A blowing fan is provided in the heat exchanging chamber(20) so as to circulate air through the heating chamber(10) and the heat exchanging chamber(20). A heat exchanger(60) is installed at a rear of the heat exchanging chamber(20).
