Last week I drained down and flushed the cold water tank, then refilled, on my 2006 331. Over last weekend we took a trip, using the engine for a few hours. When we used the taps throughout the boat, but we could not get any hot water.
The piping from the engine through the IsoTemp calorifier was hot, so I’m confused. There must be air lock in the calorifier, but as far as I can see there is no way to bleed the hot water tank.
Any suggestions ?
