The flow direction of the water is opposite to the flow direction of the flue, and when the water reaches the water outlet after being preheated layer by layer, the water is heated to the required temperature and can flow into the used place.
All technical features in the embodiment can be freely combined according to actual needs.
The foregoing embodiments are preferred embodiments of the present invention, and other embodiments are included, without departing from the spirit of the present invention.
