OK
So move the Eberespacher down to the other end of your diagram, in an alongside position to that of the "engine" and fit a couple of "Y" (diverter) valves so that the engine and the Ebers...er are connected each to an arm of each "y" (Outlet & inlet) and the leg of each "Y" is connected to either side of your water circuit.
The engine doesn't need either but the Eberspusher(thingy) would be best served if the valve switched to it's output when the heater started and it would also be better to have an expansion vessel of some type. I believe that these units already incorporate a small accumulator device already though. The valve neds to be a 12volt motorised one which opens when the heater is fired up.
See my pic.( sorry it's a bit rough - I'm supposed to be earning a living this afternoon!) - remeber too that your "Header tank" might not be needed
Actually, if you did away with Y valve #2 and just put a tee connector in there instead, it would still work and you would'nt need a second expansion tank as the engine one would serve for both, still being in circuit.**
**NO. Second thoughts, fit both and fully isolate the auxillary water heater when it's not in use. That way all the components connected to the engine will be assured of being able to take the pressure. You don't want some seal or blow-off valve in the Eberspacher loosing your cooling water at some vital motoring moment - the respective operating pressures of the engine and the Ebs'p'er are likely to be widely different.
