This is essentially the setup we have on our Hinckley, and it's great. Run the exhaust out the back of the boat, it's the only option that doesn't muck up the deck.I'm leaning toward a hydronic system such as Webasto DBW 2010, because there isn't a good place for a heater in the salon and because of the arguments outlined in the link. Living aboard full time and Winter Is Coming.
So how do people route the exhaust for these horizontal diesel burners? I think I've seen one installation with the unit mounted in a sail locker and the exhaust going straight out the topsides. But they may have a lot more freeboard than my boat does? Out the transom? That would either mean a long run for a hot dry exhaust, or I'd have to mount the thing all the way in the back - not the most convenient spot, but maybe doable. 90° up and through the deck? No good place for that around the cockpit.
There's a good place for the burner on a shelf in the sail locker, with only reasonably hellish hose runs, but the exhaust is a bit of a quandary.

That's a good point but this installation is very space-constrained. Almost all the space under the settees is taken up by the water tanks. The fridge is an engine-driven holding plate. There is an old noisy 110VAC auxiliary compressor under the sink that actually heats up the cabin quite a lot - not a critical issue but I will likely want to replace that with a 12VDC unit at some point. (Now that I'm all solared-up.) Well, in fact I could just rip it out now and put the heater blower right in there. The lower cabinet between the fridge and the sink is filled by the water heater, so quite a lot of heating going on in that corner alreadyToddster, in your plan it looks like the midship blower is near the fridge and may be close to the compressor, it might be best to move it further forward so you are not heating the refrigeration system too much.
yah i sailed a swan 65 with a Webasto …good stuff, very reliable , , stern chimneyThe Swan 65 I ran for a bit had the Webasto exhaust venting thru a screw in charlie noble on the aft deck. Great for warming your hands on a cold night at the helm. But also great at melting the flag to a ravaged mess. The outside air, heated, was awesome at drying out the interior, which is closed up in cold weather
