【7KW Parking Fuel air Heater Water air Heating Integrated Machine】specially developed for trucks, RVs, ship holds, and outdoor camping, this dual-purpose diesel heater can be used for both air heating and water heating, as well as for preheating engine coolant 【Integrated air and water heating】Diesel air heating and diesel engine coolant preheating in one, solving the problem of difficult diesel engine starting in winter, protecting the engine nozzle and extending the engine's service life. RV air heating and domestic water heating in one, with a water tank capacity of over 40 liters 【LCD display screen and mainboard ST chip control】Low-temperature resistant LCD screen displays the operating status and dynamics of the heater. When the diesel air heater malfunctions, an automatic pop-up message appears on the display screen, informing the user how to handle the malfunction. The mainboard uses an ST chip, enabling the heater to operate more stably and with better quality 【Aviation connector harnesses and high-power motors】The use of aviation connector harnesses ensures a more stable connection between the diesel water heater power supply and the motor. The motor bearings are imported from Japan, offering a longer service life and lower noise levels 【Dual drive function】When the cold air is harsh, the diesel parking heater turns on automatically to make sure there's enough heat. At altitudes above 2,000 meters, you can switch to high altitude mode to freely travel between 0 and 5,800 meters 【Energy saving and automatic carbon removal function】activated by pressing the high-altitude button, diesel heaters can save 40% of diesel fuel consumption and automatically remove up to 100% of carbon deposits. Currently 【High-temperature alarm】When the aluminum body exceeds 265°C, the diesel fuel heater automatically activates the high-temperature alarm Professional 7KW Diesel Heater: Water + Air Heating Solutions Upgrade your mobile heating system with this 24V 7000W diesel heater, designed for demanding applications like RV water heating, engine block preheating, and marine cabin warmth.
