PROBLEM TO BE SOLVED: To provide a heater which can heat quickly or can heat for a long period of time without replenishing solid fuel without emitting smoke by completely burning the solid fuel in a combustion chamber.SOLUTION: When a smoke sensor 15 detects the generation of smoke, a CPU 22 outputs a control instruction of increasing an exhaust amount to an exhaust fan 14, and carries out negative feedback control in which zero smoke emission is a target value and a smoke emission amount is an error to completely burn burning solid fuel in a combustion chamber 1. |
