Diesel Heater


Hydronic Diesel Heater (Dec-2005)

The heater is installed (Feb 28, 2006).


Quick overview of the system:


  1. Espar D5 Hydronic heater (approx 17K BTU) in port lazarette

  2. Heater hose loop across the boat (run along port-side to the v-berth and return along starboard)

  3. 7k btu blower under aft berth, 14k btu blower in main salon (both dual-speed)

  4. 3' copper radiator under v-berth (since it's hardly used)

  5. Water heater in series w/ bypass


Works well. There are still some tweaks left to be done.


Boat gets hot nicely. The only downside is the heater exhaust sounds like a small turbine/turbocharger!


Pix to come. In the meantime - here are some pictures of an excellent installation of a fellow Catalina 380 captain:
