the combustion process is completely divorced from the hot air product, also fresh air in brings fresh moisture laden air, if one recirculates the moisture is evaporated and in my case stays in the lazarette.

That seems counter-intuitive, given the amount of moisture given out by a human body/breath, I'd have thought cabin air would quickly become damp inside. Certainly my Eber, which draws air from outside, is excellent at getting rid of damp from the interior. It works a bit like a big hairdryer.

Moisture is not removed from air by heating the air, its merely turned to gas form. It will re-condense when it gets back to dew-point (temp where is condenses)
There's a continuous source of moisture being added to the air from such sources as breath, evaporation from wet things (oilies boots etc). If there's no outlet for this building level of moisture then eventually the dewpoint will be so high that even at the warm cabin temps, condensation will occur.
The moisture from combustion goes out the exhaust pipe of the heater burner, so is not part of the cabin system.
The moisture content of the cool outside air is likely to be lower than that of the cabin air, (except when its thick fog etc) Being cooler outside it will condense some of the water, and have a lower water content, so flushing this cool air into the cabin through the heater will have the net effect of removing water from the cabin, leaving a lower mosture content.

That makes sense, thanks!
