We also run redcorvette's Dickerson propane bulkead heater - not as bulky as some other heaters, and if you have propane on board already that's not an issue either. As he said, no moisture issues as combustion air is piped in from outside and flue gases are vented outside as well, of course. Both include a circulation fan that works well (greatly boosting efficiency) but is rather noisy at high speeds, my only complaint.
It also has a glass door, providing a pleasant ambience of a visible flame - "fireplace" style. They produce a 9000 and a 12000 btu model, we have the 9000 on a 35' boat and had the 12000 on our last boat, a 40 footer. The smaller heater seems adequate on all but the coolest days.
The espars and their ilk make sense in a lot of ways, but during our last purchase process we saw many boats with espars etc. installed but not included in the listing because they no longer functioned. This put us off these types somewhat. On the noise issue, I think that's more a problem for your slip neigbour than for those onboard.
