Hmmmm, hasn't been a problem with my pipes. I put cabin heat in last winter (and love it!). I put a shroud along the pipe that runs back from the left front cylinder - the straightest and longest stretch of pipe I've got, and I'm comfortable in a T-shirt even with the bitterly cold days we have in San Diego in the winter. No really . . . despite the balmy reputation SoCal has in the minds of many who live in places like Minnesota, it does get surprisingly cold here. I've seen it in the low 50's. I used the silver duct hose from a local VW shop to pipe the heat to a heat box on the firewal with a flapper valve controlled by a cable with a friction lock handle on the panel - strictly the old conventional airplane heater shroud idea. There's a leak or two or three or four where the shroud joins the pipe and I would have patched them if heating was marginal - but it's not. It's more than ample for the coldest days and very, very nice for winter flying. So Dan, I haven't seen an "issue" with getting heat off the jet coated pipes. I've had carb heat all along and use it for winter flying. With the Ellison I don't think I've ever had carb ice but use carb heat anyway a lot of the time to help with evening out the mixture temperature? Is that why I do it? Mark said why it's a good idea to use carb heat in the winter . . . I don't remember just now why I do it.
