I am not quite sure exactly where to disconnect the coolant
hose loop on my Yanmar 3YM30 engine
in order to heat my new hot water
I have read through the engine's manual, but fail to find exact relevant info where to find and make an external coolant
liquid loop. Could someone give necessary info?
In order to make the engine's external loop as short as possible, I intend to have a separate but thermally connected loop with a passive heat exchanger
of the kind used in domestic gas boiler systems and in some RVs.
