With the global rise of RV camping culture and the prominent range anxiety of new energy commercial vehicles (especially electric light trucks) in cold regions, air-water integrated heaters are rapidly transitioning from “optional” to “standard” equipment. Traditional fuel vehicles face engine cold-start wear issues in winter, while electric trucks suffer from significant range reduction due to battery performance degradation at low temperatures. The integrated heater, through a single diesel combustion system, simultaneously outputs warm air and hot water, perfectly addressing these pain points. Industry data shows that in 2025, the growth rate of this sub-category in the European and North American markets exceeded 40% year-on-year. Industry experts predict that with countries raising vehicle energy efficiency and emission standards, integrated heating systems featuring efficient combustion and intelligent temperature control will become core components for the next generation of special vehicles and outdoor equipment.
