Excellent point. I hadn't thought of that.
One soulution would be to just leave it open all the time, but that would add more cooling load onto the radiator. Of course, especially when it's cold I don't need anywhere near as much radiator as I have.
I guess another option would be spliting the exhasut pipe (one leg normal, one leg with the heat echanger) and putting a bypass valve in, but then we're getting more complicated than I'd like.
