24 VDC appliances?
Del, did anyone ever inspect the dampers to see if they were opening?
The air cooling coming out of my 1KW Honda EU1000i genset, a tiny engine, more than adequately heats my Air Force stepvan at 30F in 30 minutes. A couple of loops of copper tubing heat exchange more from the exhaust before it goes outside through the deck.

I've never figured out why boats in cold climates waste all this energy going out the exhaust. It's SO easy to make a cast iron heat exchanger in a dry stack, right next to...or even right IN the exhaust manifold that will just roast your ears with free heat. the old Volkswagon Beetles used a heat exchanger off the exhaust manifolds to heat the car! It was actually pretty nice on cold mornings, as the heater worked almost instantly after starting the car. Are you insane? Suffering from Amnesia? We had one of those Beetles in Minnesota from 1973 until 1985. My wife used to wonder why the other people in the grocery store weren't wearing snowmobile suits. We learned to drive one handed so we could scrape the inside of the windshield with the other. Do you realize how long it takes to heat a piece of cast iron and the sheet metal floorpan duct when it starts out at zero, and the heat is coming from 750cc of motor (there were two, so each only got half the exhaust) Sheeesh. del cecchi |
