Hello all.
On my PSC 34, the engine is not heating the water in the hot water tank.
It will heat when connected to shore power. Due to some hull damage repairs, I am only getting the boat ready now and have not tested the water system until now. Last fall the engine/heat exchanger loop fluid was replaced, and the water tank drained and filled with non-toxic anti-freeze as used to winterize RV plumbing.
An 1.5 hour engine run yesterday yielded no hot water but the engine seems to run fine and not overheat.
I am trying to understand how this system works. I assume the engine heat exchange liquid is circulated through the hot water tank, not the heated waste water leaving the heat exchanger. Is fluid directed to the hot water tank before the thermostat opens? Is it possible there is an valve preventing flow to the water tank? Maybe there is a mechanical or electrical pump which I am not thinking of?
Thanks for any help or ideas on how to track down the problem.
Regards, David
