It will be a great addition for that trip also.
You might consider a free standing directvent stove such as the Toyo OM2. We have had one aboard for almost 7 years with NO problems. Sure, there designed for homes, but we liveaboard in Alaska almost all year and it is economical to operate, very easy to install, pulls fuel directly from the main fuel tank, and really cranks out the heat. Several folks mentioned these stoves are not designed for use with #2 diesel fuel, but the OM22 is and it's been flawless. There have been no problems running it underway in the worst weather either. Were in the whole thing for well under $2000.00 The down side is that it won't heat any area below it's own level. Ours is in the salon where we spend 90% of our time, but it doesn't do much for the lower areas of the boat. When we want heat there I run either a fan/coil unit utilizing waste heat off the engines, an Espar DL7 (which I rarely run) or electric.
Would I prefer a nice hydronic system? Sure, but the cost to purchase, install and run is so high that I can't justify it. Our system is far better in most respects (noise, power consumption, fuel consumption, size, complexity and more) that it's not worth it. We couldn't be happier with our set up................Arctic Traveller
