Autoterm Flow 5D Hydronic Diesel Heater 24V for RV Campers The Flow 5D Hydronic Heating System from Autoterm is a compact, diesel-powered solution designed to keep engines ready and interiors comfortably warm in the harshest conditions. This independent heater installs quickly in a wide range of vehicles, boats, and campers, and can connect to your coolant circuit or a central heating system to deliver warm air and reliable pre-heating—even when the engine is off. Why Flow 5D stands out Rapid, powerful warmth — up to 5 kW of heating power at 12V, enabling fast engine pre-heat and swift cabin warming. Extreme cold protection — automatically helps the engine reach and maintain proper operating temperature in temperatures as low as -45°C, reducing cold-start wear. Efficient, quiet operation — brushless induction motors provide long life and low noise in demanding environments. Low fuel consumption — draws diesel at a maximum rate of 0.6 L/h, preserving fuel for travel while delivering dependable heat. Flexible installations — designed to connect to the vehicle’s coolant system or a central heating loop for boats and campers, with a compact footprint ideal for tight spaces. No ducting required — streamlined installation with fewer parts, plus the option to add an extra fuel tank if needed.

RV, camper, and boat owners seeking efficient central heating and engine pre-heating without idling the engine. Fleet vehicles operating in cold seasons that require quick pre-heat to reduce start-up wear and keep drivers and passengers comfortable. DIY enthusiasts and installers looking for a robust, scalable heating solution with broad compatibility in cooling and fuel systems. How Flow 5D works and why it matters As a hydronic heater, Flow 5D circulates heated coolant through the engine block and/or an external central heating loop. By pre-warming the engine, it reduces rough cold starts and engine wear. At the same time, it channels warm air into living spaces, so you can step into a ready-to-go interior after exposure to freezing weather. When the engine is running, the system helps maintain a comfortable cabin temperature; and it can deliver warmth even when the engine is off, ensuring you stay cozy in parked scenarios.
