AUTOTERM Flow 5D / 5B Campervan Water Heater Kit 5kW (Previously BINAR 5S)

The AUTOTERM Flow 5D / 5B is a powerful 5kW diesel or petrol water heater designed to preheat your vehicle's engine and provide warm coolant for your vehicle's heating system before you even turn the key.

Previously known as the BINAR 5S, the AUTOTERM Flow range offers outstanding reliability, low running costs and exceptional cold-weather performance. By circulating heated coolant through the engine and vehicle heating system, it reduces engine wear, improves cold starts and helps maintain a comfortable cabin on frosty mornings. It is a practical campervan water heater for drivers who want dependable preheating and improved winter comfort.

Ideal for campervans, motorhomes, commercial vehicles, boats and off-road vehicles, the Flow 5D / 5B can also operate as an auxiliary heater while driving in extremely cold conditions.

Why Choose the AUTOTERM Flow 5D / 5B?

The AUTOTERM Flow heater operates completely independently from your vehicle's engine, allowing you to:

• Preheat your engine before starting

• Eliminate cold starts

• Reduce engine wear

• Warm the vehicle cabin using the existing heating system

• Improve comfort during winter driving

• Maintain engine temperature in extreme conditions

Unlike an air heater, the Flow heater integrates directly into your vehicle's coolant circuit, meaning no additional warm air ducting is required. It is designed to work with the existing coolant system to support reliable water temperature control and cabin heat.

Please Note: Some newer vehicle models may require an additional EPCU (Electronic Climate Control Unit) module to activate the vehicle's cabin fan when pre-heating.
