Detailed Overview of the Autoterm 44D 24V Diesel Air Heater
The Autoterm Diesel Air Heater 44D series, especially this 24V 4kW model, is designed to provide rapid and reliable heating in large spaces up to 120 cubic metres. Whether you’re on the road, out at sea, or fixed in an off-grid location, this heater ensures a cosy environment under low temperatures down to -45°C.
The unit draws fresh air from outside or a ventilated area, then heats it efficiently before distributing warm air throughout the space. Its brushless motor means reduced noise and extended durability, critical for those long trips or prolonged stays in cold climates.
Installation and Versatility
The heater kit comes complete with everything needed for straightforward installation, including fuel pump, air intake hose and silencer, exhaust pipe, mounting brackets, and all cables. This makes it equally suited to retrofit into large land vehicles, marine vessels, caravans, or even small off-grid buildings like mountain retreats or shipping container conversions.
Energy Efficiency & Controls
Operating on diesel fuel, it consumes a low 0.51 litres per hour at maximum output while maintaining silent performance thanks to the advanced induction motor technology. The included rotary controller is easy to use and allows precise temperature adjustment to your preferred comfort level.
For enhanced convenience, an optional modem is available to control the heater remotely via your iOS or Android smartphone, ideal for starting the heater before you arrive.
