Above-mentioned body of heater, furnace upper cover, upper water box, middle water tank and lower header are made by cast iron.

Because the utility model has adopted version and lower header, middle water tank, upper water box, furnace upper cover and body of heater that lower header, middle water tank and upper water box are set in furnace chamber all to be made by cast iron, therefore, compares with background technology, has following advantage:

1, upper water box, middle water tank and lower header are cascaded from the top down, make three water tanks be subjected to different heat radiations, all allow water fully absorb conversion heat energy, and the thermal efficiency reaches more than 90%;

2, lower header, middle water tank and upper water box are arranged on the top of flue, do not influence the abundant burning of fuel, reach the purpose that is sparing in the use of coal.Compare with equal hot-water heating stove, can be sparing in the use of coal about 1/3;

3, the critical piece of this stove is all made by cast iron, so its production cost reduces by 50% than steel plate soldering furnace, and corrosion resistance improves more than 5 times.

The utility model had both gone for the warming of general family, also applicable to the use of having a bath.

The utility model will be further described below in conjunction with drawings and Examples.
