Question 6: Does the heating stove belong to a boiler? Is it special equipment? In the course of thermal energy dynamics in university, an old professor gave a very simple definition of boiler, that is, combining boiler with furnace, and the heat generated by furnace can be used to heat boiler. So much for the so-called brilliant scientific explanation. It can be seen that the heating furnace is only a heating device, so it is not a boiler, but a special device.
