    The EGR cooler would be a little small would it not? A purpose built exchanger would  be the way to go, finances permitting.

    Can't beat free, had no idea it was so large, mostly I've worked on smaller diesels 1.6 to 4 liter and most of those had no EGR. Good for you hope it works out well, keep us updated on your progress, interesting stuff.

    I used a stainless steel swimming pool water to water heat heat exchanger.
    Works good ,egt in around 800F. and egt out 350F. So far it's held up good,and with the threaded connections it was fairly easy to hook up.
    It's starting to soot up alittle so the temp out has been rising slightly.
    What ever you use plan on cleaning it out at some point.

    I have thought about a easier design,where the exhaust goes through a pipe(or 2 or 3) surrounded by a larger "buffer tank",with the engine coolant also plumbed to this tank. Then draw the heat for your heating system off of this tank. Would simplify piping as it's a challenge to get all the flow rates right through multiple heat exchangers.
