The advantage of hydronic or any combustion, vented appliance is it changes the inside air, removing moisture from the boat. All steam from cooking and showers plus moisture from your breath stays inside the boat unless vented. Most people with electric heat close up their boat tight and then wonder why their clothes and bedding are wet or damp.
I have a hydronic system with one or two forced air heaters in each cabin. I have a boiler and a Webasto. I have an 83' boat with 5 zones. In the winter unused cabins are set to about 50°F. In 20°F weather either boiler or Wabasto burns about 5-6 gallons a day. But I usually run a pellet stove 24/7 with water coils that heat the boiler for about 2-40# bags a day. About the same cost as heating with $2/gallon diesel. When diesel was over $4 I installed the pellet stove.
My relative humidity usually runs 40 - 50% in coastal Oregon even when it's raining or foggy.
