When we went to view Herbie it was a bitterly cold afternoon, but inside with the solid fuel stove on it was really warm and cosy. The radiator you can see is separately run from a diesel fuelled heater which lives in the engine compartment. There are other rads in the loo and in the bedroom at the front.
Apparently you don't need the rads if the fire is lit, but they should be handy for a quick burst of heat either when its not worth lighting the fire or while you're setting the fire. On the right you can see the light coming through the open side hatch. Forget the nick nacks, the video etc - they don't come with the boat. Kath has alreay decided to replace the curtains and cushions with something less cottagey.
