To provide a construction machine including a novel preheating unit that can efficiently preheat entire circulation channel where fluid flows, and a preheating method of the construction machine. A bypass channel (66) is arranged in a circulation channel (60A) through which the fluid is circulated, this bypass channel (66) is provided with the preheating unit (67) that is formed of a heater (67b) and a bypass pump (67a). According to such configuration, even in a state circulation of the fluid may stop in the circulation channel (60A), the fluid can be heated while the fluid is circulated through the bypass channel (66), and therefore the entire circulation channel (60A) can be efficiently preheated. Moreover, since retrofitting to the existing circulation channel (60A) is possible, sound versatility can be exerted.
