VELIT Gasoline/Diesel Air Heater 14000Btu 4000W

The Velit 4000P delivers powerful, safe heat for off-grid and mobile living, with built-in carbon monoxide and flammable gas sensors that automatically shut the unit down if dangerous levels are detected. Tested above 11,000 ft in Colorado, it dynamically adjusts its air-fuel mix based on barometric data to minimize carbon buildup and maintain performance at high elevation — and with Bluetooth control up to 100 feet away, you can manage it right from your phone.
