AUTOTERM Flow 5D/5B is a highly versatile liquid heater also known as a water heater that operates independently from the engine. Previously known as BINAR 5S. This compact heater has a 5-kW heat output and is designed to pre-heat a vehicle’s engine and compartment, thus eliminating cold start of the engine, and extending its lifetime, whilst working in unison with the car salon fan to supply comfortable warm air to the passenger compartment in the cold season. Newer car models may require a third party EPCU block to heat the passenger compartment.
As the heater is linked to a vehicle’s coolant system, there is no need for additional air ducting to provide warm air to the passenger’s compartment.
This product is offered for 2 types of fuel systems: Petrol (B)– 12V / Diesel (D)– 12V or 24V
In extremely cold environments, the AUTOTERM Flow 5D/5B pre-heater also works as an auxiliary heater, helping the engine to reach and maintain automatically its optimal working temperature was necessary when driving.
AUTOTERM Flow 5D/5B, with its diverse installation options, can also be used as a heater for small radiator systems or boilers with a maximum capacity of 30 litres. This product is best suited to those who want to add heat vehicles with an engine capacity of up to 4 Litres, motorhomes or boats with liquid heating systems.

ASK A QUESTION ABOUT THIS PRODUCT
Hi,
Thanks for your question.
Yes, the AUTOTERM Flow 5D/5B (5kW) would generally be suitable for a 45ft narrowboat with 3 radiators and a calorifier. That’s a fairly typical setup for this size heater, and it should provide adequate output for both space heating and hot water.
The key things to ensure are:
If everything is installed correctly, the 5kW unit should work well for your application.
Yes, as long as the fuel line is IOS 7840 compliant and you purchase this with a marine exhaust silencer and hull fitting, this will be compliant for inland waterways.
We sell all the parts separately on our website. If you need any help, just drop me an email — I’m happy to assist you.
