Yes, this is such a heater.
But I would not want to carry with me a diesel superheater and a 10-liter tank to it .. And to call in to fill an electric car with a diesel engine .. It will look ridiculous. =)

I'm still not sure I want to do this but, it would certainly minimize the range hit in winter. Also you would be toasty warm with no range hit. If I have the time next summer I may tackle this. I will have to double check the fuel consumption rates but I think even a 1-3L tank should be plenty big. Plus I would use kerosene for a cleaner burn.

I was browsing through the document provided by Dobrinia and noticed that water pump is listed as an Ancillary Option.
https://www.eberspacher.com/fileadmin/d ... _jn600.pdf

Would adding the optional water pump improve efficiency? Based on the spec document, it looks like you would also need the optional controller.

Ancillary Options
Water pump: A 12V DC water pump
(P/N 25 2526 25 00 00) is available rated
at 720l/hour which is matched to work with
the controller (option B). Other pumps in 12
and 24V DC are available on request.

The pump is not built into the heat, an external one is required.
If you install an additional pump, it will not increase efficiency, alas.

I know two ways to solve problems:
1) installation of diesel / gasoline / gas additional heater.
2) heat pump installation (I plan to do this in summer)

Can you share some tips about the heat pump installation you're planning? I'm interested to do it as well. Maybe we can help each other out.

prop1 ,
I think it will be difficult for me to explain the principle of work, since I use a translator to communicate on the forum. You can google "heat pump" and read about its principles of operation. It works as an air conditioner in heating mode.
I plan to put an additional radiator for the main, for the heat pump.
And an additional heat exchanger that will heat the coolant.
The performance of the heat pump will be adjusted using the PWM signal, which now goes to the standard heater. The heat pump will be powered from the wires of the standard heat exchanger.
I have experience creating a heat pump that is heating my home now. Everything will work out!

Prop1 I believe Dobrinia already mostly covered this but just for clarification. The FFE already has a pump in the heater coolant loop. The heater requires a pump for operation but it is not built into the heater. I believe Eberspacher listed that pump as an option in case the application one was planning to use the heater did not already have a pump circulating the coolant.
