With this integrated design, the following scenarios apply:
Fireplace in use:
Central furnace is turned down
Oven in use:
Central furnace is turned down
Central hot water AC is turned off
Main engine in use:
Central hot water AC is turned off
Central furnace fails:
Fireplace and oven provide central and space heat
Central furnace and distribution system fail:
Fireplace and oven provide space heat
Shore AC power fails:
Oven provides hot water
DC-AC inverter provides electricity to hot water elements

Finally, some heating has to be provided to the engine room to keep water tanks and pipes from freezing. Obviously some further development is required in the design of the back-up heating. Increasing the output of the diesel stove is not a good option, as this would tend to make it less useful as a cook stove. Perhaps the Bubble should be re-located to the aft cabin, but this negates its lifestyle purpose. More practical solutions are to shut off the water to the aft head and run the engine to keep the engine room warm. Another solution is to have an aft engineroom and a contiguous forward accommodation space.
